Objective:
Since 1998, researchers of the University of Washington Center for Child Environmental Health Risks Research (the Center) have been using a multi-disciplinary research approach working in the lab, in the field, and in the community to understand the mechanisms that define childrens susceptibility to pesticides, identify the implications of this susceptibility for development and learning, and partner with our communities to translate our findings into risk communication, risk management, and prevention strategies. The Center is jointly funded by the National Institute of Environmental Health Sciences (NIEHS) and the Environmental Protection Agency (EPA).
The Center is administratively housed within the Institute for Risk Analysis and Risk Communication, also directed by Center Director Dr. Elaine M. Faustman, which is in the University of Washingtons School of Public Health. The Center includes partnerships with the Fred Hutchinson Cancer Research Center and the Yakima Valley community, located in the agricultural center of Washington State, to jointly sponsor a Community Based Participatory Research (CBPR) Project aimed at reducing childhood pesticide exposure.
All Center efforts are highly integrated with two field-based research projects, two laboratory-based research projects, three facility cores, an Administrative Core, and Faculty Development Investigator.
The specific objectives of the two field-based projects—the CBPR project and the pesticide exposure pathways research project—are to:
- Improve our understanding of critical pathways of potential pesticide exposure for children; and
- Apply culturally appropriate interventions to reduce childrens exposure to pesticides.
The specific objectives of the laboratory-based research projects—a molecular mechanisms research project and a genetic susceptibility research project—are to:
- Identify cellular, biochemical and molecular mechanisms that cause adverse developmental neurotoxicity of pesticides; and
- Identify susceptibility factors for developmental neurotoxicity of pesticides.
The three facility cores are: Biomarkers and Exposure Assessment (BEA); Biostatistics, Modeling and Risk Characterization (BMRC); and Community Outreach and Translation (COTC). The cores are designed to support the research objectives and to put the research into a child-specific risk assessment context. Thus, the specific objectives of the facility cores are to:
- Provide core support for the development and application of risk assessment methods, enabling basic research on pesticide toxicity and exposure to inform risk decisions to protect childrens health from pesticides; and
- Foster partnerships between academic researchers and the community in which information requested by the community and basic research deficiencies/gaps are translated into studies that address the needs of both.
The Administrative Core provides fiscal oversight, resource management, coordination, and integration of Center activities. The COTC shares membership with the Administrative Core and includes Dr. Catherine Karr, who since 2009 has served as the Centers Faculty Development Investigator, as well as a Pediatric Health Specialist. Center support and mentoring enable Dr. Karr to capitalize on the complementary and collaborative resources at the Center in order to navigate the transition to an independent investigator in this subject area.
Work in the Center is organized around the Public Health paradigm V-diagram, which connects occurrence of disease in humans to the original source of the problem (see Figure 1). Along the pathway from source/stressor to disease, the diagram identifies intermediate processes (which may be subject to public health intervention) and conditions (which may be observable for public health monitoring and hypothesis testing). This paradigm is central to the overall organization and integration of the various components of the Center. Using Global Positioning System (GPS) tools to relate human activities and land use helps identify how organophosphate (OP) pesticide (stressor) application is transferred/transported to create OP environmental exposure conditions. The CBPR Project focuses on the multiple pathways of OP transfer to identify potential exposure and resulting dose in children. The biological sampling efforts help identify susceptibility factors and genetic mechanisms relating dose to early biological effect. Biostatistical analyses and outreach link these research components together.

Progress Summary:
Community Based Participatory Research Project
A key feature of the Center is the CBPR Project, which identifies the multiple potential pathways that may contribute to pesticide exposure in adults and children living in agricultural communities. Unlike many other studies of potential pesticide exposure, the CBPR investigators have used a group randomized trial design. Advantages of such an approach are the potential to reach large numbers of people, disseminate messages about behavior across a diverse population, change community norms about behavior, and integrate new behavioral practices into existing community structures and organizations. Part of the study design requires early involvement from the communities to guide us in planning intervention activities. The results of this research support the hypothesis that the take-home exposure pathway contributes to residential pesticide contamination in agricultural homes where young children are present.
The highlights of this past year include two Community Forums held in February 2013 in order to share information on the importance of donating specimens to biomedical research. The first was held in English for the Community Advisory Board, and the second was held in Spanish and was open to the community. These forums were a joint effort by Dr. Thompson with the CHC Center and Dr. Thompson's Community Based Participatory Research Project and NCI-funded Community Network Program Center (CNPC). The forums provided an opportunity to be transparent about the knowledge we hoped to gain from this study, and allowed us to gauge the audiences' understanding of our work. In the final phase of the study, dissemination tools will be designed with the feedback from these two forums in mind.
Pesticide Exposure Pathways Research Project
The Pesticide Exposure Pathways Research Project's overall aim is to develop a systematic understanding of residential pesticide exposure pathways arising from proximity to agricultural spraying in rural agricultural communities where children live. The proximity exposure pathway is due to transport of pesticides from applied fields to homes and other settings. The mechanisms of transport include spray drift, volatilization, re‐suspension and deposition of particles containing pesticides. The Pesticide Exposure Pathways Research Project studies both local pesticide application factors and human activity factors that contribute to childhood exposure to pesticides.
The highlights of this past year include air sampling to measure concentrations of airborne organophosphate pesticides (chlorpyrifos, azinphos-methyl) and oxon analogs at 20 participant homes. Chemical analysis using LC-MS-MS in the Environmental Health Laboratory was completed for ~150 samples. The data analysis for the initial results has been prepared for publication. Fieldworker observation and public land-use data were used to specify type of crop for proximal homes, emphasizing homes that were near tree fruit fields. This information will be used on the next stage of analysis for building exposure models.
These efforts address key aims of the current study by directly measuring exposures to OP pesticides inside and outside the participant homes and examining the potential contribution of the take-home and proximity pathways. PUF-PAS (polyurethane foam passive air sampling) disks have been developed and tested as a novel sampling device for studying pesticide exposures. PUF-PAS is highly effective for capturing airborne organophosphate pesticides while minimizing invasiveness to research participant families. Over 90% of the study participants that were approached participated in the air monitoring portion of the study, and only one passive sampling instrument had a failure. A paper has been submitted describing this new sampling method.
Our initial field results show that residences proximal (< 250 m) to fields experience higher monthly outdoor levels of chlorpyrifos and azinphos-methyl than non-proximal homes (> 250 m). Farmworker homes also experienced higher levels of outdoor pesticide concentrations, but this may be attributable to a relationship between increased proximity to tree fruit orchards and increased outdoor pesticide concentrations. Many farmworker homes were located in agriculturally dense areas. This is the first major study to validate a passive sampling device for OP pesticides and their oxon analogs. Passive sampling provides average exposures estimates over the course of several days and will dramatically enhance our ability to survey more participants and to collect samples over the course of an entire season. Both proximity and take-home routes contribute essentially independently to airborne OP pesticide exposures. This information will be a direct benefit for constructing exposure estimates for longer term epidemiological cohort studies in the future.
Molecular Mechanisms Research Project
One of the objectives of the Molecular Mechanisms research project is to understand how exposure to chemical and nonchemical stressors can impact childrens' neurological developmental processes. In order to prevent and predict developmental neurotoxicity, it is important to understand the who, what, where and when of chemical and non-chemical stressor biology and exposure. A key focus of this research project is to understand who is exposed, to which environmental chemicals, where the exposure is coming from and to identify biological impacts occurring across the life-course. For example, the Center investigates how an exposure early in development may differ significantly from impacts seen later when exposures occur at a different stage of development of life-course (toddler versus early school age children). Once we have characterized the exposures, we can use this information to make predictions about chemicals that could adversely impact neurodevelopment and then take action to prevent those exposures, especially in susceptible populations, such as children or pregnant women.
Our Center is particularly interested in pesticide exposure across the life-course. Pesticides can have adverse impacts on brain and nervous system development by altering the regulatory dynamics of normal central nervous system cell proliferation, differentiation and cell death, which can result in altered morphogenesis. These alterations are correlated with subsequent deficits in learning and development. A thorough understanding of mechanisms of toxicity at the molecular, cellular and organism level is therefore important as these mechanisms may define unique life stages that may be windows of susceptibility for many neurodevelopmental toxicants as well as for pesticides. The Molecular Mechanism Research Project evaluates these mechanistic processes across several pesticide classes in order to understand the commonality and uniqueness of pesticide toxicity across dose, life-course, cell type, and behavioral domain.
This research project brings together the expertise from different laboratories to focus on the relationship between pesticide‐induced alterations in cell proliferation and death during embryonic/postnatal development and postnatal alterations in behavior. These projects use rodent models and follow both in vivo and in vitro impacts. The laboratory of Dr. Elaine Faustman addresses the impacts of pesticides and model neurotoxicants on prenatal processes generating neurons, known as neurogenesis, and the laboratory of Dr. Lucio Costa evaluates the postnatal effects of pesticides on processes of generating non-neuronal glial cells, known as gliogenesis.
In the last several years, the Faustman lab initiated studies to explore new in vitro models for the evaluation of neurogenesis including assessment of proliferation and differentiation processes for in vivo comparison. The highlights of this year include an in vitro human neural progenitor cell model that was established to study adverse effects of the OP pesticide chlorpyrifos (CP) during neuronal proliferation and differentiation. Using confocal imaging to characterize cell-by-cell expression of markers of differentiation and proliferations will help illuminate developmental processes occurring in these cell cultures through both normal development and when perturbed by pesticide exposure. Understanding these dynamics will help improve and stabilize culture conditions to more accurately reflect in vivo developmental processes. Towards this goal, the researchers have characterized protein expression and this expression has been compared to the Allen Developing Mouse Brain Atlas reports on gene expression. The researchers have included not only in vitro human neuronal progenitor cells with in vivo murine brain development but also have added a comparison with their in vitro murine Central Nervous Systems micromass cell cultures.
Another highlight of recent work are the results of our studies suggesting that epigenetic factors play a role in the neurodevelopmental effects associated with CP exposure. For example, toxicogenomic profiling of CP exposed fetal and maternal mouse brains showed significant alteration to chromatin modifications. Exposure to CP during critical windows of susceptibility has been reported to alter behavior and development of the central nervous system by interfering with the regulatory pathways that control the production and selective cell loss of neurons. These results showing differential alterations of epigenetic markers during proliferation and differentiation can offer cell stage specific mechanistic information to help researchers tease out neurodevelopmental effects of the organophosphate pesticide CP.
The focus of Dr. Costas' project is the investigation of glial-neuronal interactions in neuronal differentiation. Work in Dr. Costas' laboratory has focused on the OP pesticide diazinon (DZ) and its active metabolite diazoxon (DZO). As both have been shown to induce oxidative stress in neurons, and based on previous studies with manganese, it was hypothesized that these OPs may induce oxidative stress also in astrocytes, and that this would impair the ability of these cells to induce normal neuronal differentiation, which is necessary for healthy neurological development. In our recent work, both DZ and DZO induced oxidative stress as assessed by measuring levels of reactive oxygen species (ROS) in rat cortical astrocytes. In separate experiments, the ability of OPs to directly affect neuritogenesis was also investigated. In this experimental protocol, neurons were cultured alone, in the presence of astrocyte-conditioned serum, but not in co-culture with astrocytes. Preliminary experiments indicate that when co-incubated with neurons, astrocytes are capable of increasing the levels of the protective antioxidant, glutathione (GSH). The increased GSH levels in neurons would thus explain their increased resistance to OPs. This was further confirmed by raising GSH levels in neurons with the use of GSH ethyl ester.
The complementary objectives of the Faustman and Costa laboratories have contributed to the advancement of our understanding of the potential for, and magnitude of, impacts of pesticides on neurogenesis and gliogenesis. In both of these essential neurodevelopmental pathways, the balance between initial proliferation and subsequent specific differentiation is integral for proper neurodevelopment. The integration of the Faustman and Costa laboratories allows us to better understand the molecular mechanisms that can cause adverse neurological development in children, following pesticide exposure. Our investigation of critical molecular pathways facilitating proliferation and toxicant response allow us to better predict neurological toxicity and increase our understanding about the importance of timing of exposure. The results from this project can be used to identify particularly vulnerable or sensitive populations and can be translated into information relevant for establishing conditions promoting environmental and public health safety.
Genetic Susceptibility Research Project
Activities of the Genetic Susceptibility Research Project have contributed to a greater understanding of the role of gene-environment interactions that define childrens' susceptibility to OP pesticides. This project interacts with many of the lab and field-based CHC projects as well as with many external collaborators. In particular, this project interacts with the Centers for Disease Control and Prevention (CDC), Environmental Protection Agency (USEPA) Region 10, Agency for Toxic Substances and Disease Registry (ATSDR), the University of California Berkeley Center for the Health Assessment of Mothers and Children of Salinas (CHAMACOS), Washington State Department of Health, Washington State Pesticide Incident and Reporting Panel (PIRT), other U.S. government agencies, the United Kingdom (UK) Committee on Toxicity and several members of the UK Parliament.
The overall goal of the Genetic Susceptibility Research Project is to develop specific biomarkers of exposure to OP compounds and to use these biomarkers to explore gene-environment interactions related to genetic variability in the paraoxonase (PON1) gene, particularly with respect to OP exposures that occur during early development. The results of this project have helped create new more sensitive techniques for assessing pesticide exposure and greatly contributed to our understanding of how genetic differences in pesticide metabolism pathways impact adverse health responses across the life-course.
This project is developing many new techniques for the detection of adducts in blood samples that are associated with specific pesticide exposures. Highlights of the past year include experiments demonstrating that a single step immunomagnetic bead protocol will purify butyrylcholinesterase (BuChE) from plasma and acyl peptide hydrolase (APH) from red cell extracts. The OP adducts to these proteins have been identified. The serine adduct from the active metabolite of tri-cresyl phosphates was found to undergo a unique aging reaction. In vitro inhibition of BuChE with the active metabolite of TCP, cyclic saligenin cresyl phosphate (CBDP) generated both a cresyl phosphoserine and an aged phosphoserine. However, in samples from exposed individuals, only the fully aged phosphoserine modification was observed. More recent experiments have shown that acetyl cholinesterase (AChE) does not age in the same way and retains a cresyl group. We are currently developing methods to process samples for characterizing this adduct. Further, we have generated deuterated metabolite CBDP for generating in vitro heavy isotope labeled AChE for use as an internal standard. Characterization of the adducts on the active site serine of BuChE inhibited in vitro with chlorpyrifos oxon (CPO) showed the expected di-ethyl and aged mono-ethyl adducts while inhibition with azinphos methyl oxon generated the di-methyl and aged mono-ethyl serine adducts. An excellent correlation between our methods was developed. This was for the single step MS analysis of the active site serine of BuChE compared with the BuChE activity inhibition measurements made with thinning and non-spray season blood samples. These new techniques allow us quantify the effects of pesticide exposure with only one blood sample, rather than the requisite two samples needed by most current protocols.
One of the primary aims of this project in the previous funding period was to evaluate the effects of exposure to CPO during early postnatal development and to determine the role of the human PON1-Q192R polymorphism in modulating these effects, using multiple endpoints of OP toxicity. In the previous year, pilot studies were completed that determined steep chronic dose-response curves for inhibition of uBChE and AChE in pregnant and non-pregnant mice. Timed-matings and exposures of pregnant mice were completed. Mice with copulatory plugs were exposed transdermally to CPO daily. Dams were sacrificed, and fetal and maternal tissues were dissected for measurement of enzyme inhibition in different tissues. The PON1 status of the dam was found to clearly influence CPO toxicity to the fetus. RBC APH was found to be the most sensitive biomarker of CPO exposure, a particularly interesting finding given the potential importance of brain APH for cognition. A manuscript describing these data is in preparation. Because these same polymorphisms exist in human populations, understanding the changes in susceptibility of pregnant mice with varying PON1-status will help characterize human variability and identify similarly susceptible populations.
Additionally, a positive, linear correlation was found between plasma PON1 activity and AChE level of both brain and diaphragm in treated mice, indicating that plasma PON1 can serve as a susceptibility biomarker for DZO toxicity. Our research found that RBC APH is a useful biomarker for DZO exposure because of a good correlation between APH inhibition and AChE inhibition in brain and diaphragm. A manuscript describing these findings is now in preparation.
Biomarkers and Exposure Assessment Facility Core
The Biomarkers and Exposure Assessment facility core has focused on samples collected in the field. This core has coordinated their analysis for chemicals and other biomarkers of exposure and effect as well as characterized genotype and phenotype. A strong emphasis has been placed on providing analytical support for field samples collected by the CBPR Project and the Pesticide Exposure Pathways Research Project. The Core stores the results of the analyses and assists investigators in their interpretation. The Core also has provided support to the Genetic Susceptibility Research Project through the identification and development of relevant biomarkers.
Most recently, samples from the CBPR study were collected earlier in the year than in prior years to capture the time of CP pesticide use. The samples collected in the early spring that had not been collected in previous studies has allowed us to capture exposure to different types of OP pesticides, mainly CP, that are applied during this time. Samples also were collected during the early spring, late spring-early summer (to coincide with the timing of previous sample collections), and again in the off season during winter. Because children were older in our most recent field visit, it was possible to collect whole blood from the children so that we can examine a wider variety of biomarkers. Based on our results from our previous studies, we have expanded the list of biomarkers that are being studied.
The Core helps investigators develop new biomarkers, ranging from indicators of exposure to early markers of potential disease. The expanded analyses of OP parent compounds since 2009 includes selected oxons of OPs since these have been detected in environmental samples and are much more toxic than the parent compounds.
The Core collaborates closely with the UW Environmental Health Laboratory and Trace Organic Analytical Center and other laboratories to carry out these analyses. The Core continues to monitor and maintain the Center's biorepository and associated IRB applications and requests. Additional funding has been obtained from the National Childrens Study (NCS) to analyze samples in the biorepository collected in past Center studies. The results of these additional studies will be used to inform the Main NCS study as to best practices for the collection, storage, and analysis of field collected samples within a large longitudinal study. The Center has examined an expanded list of pyrethroids, neonicotinoids and fungicides. During the past year, this Core has coordinated analyses on field collected house and vehicle dust samples. Specifically, we characterized the occupational farmworker (FW) vs non-farmworker (NFW) and seasonal profiles for 16 organophosphate pesticides (OPs), 71 other pesticides, 22 metals, 18 phthalates and 50 molds. The analyses on molds in dust coordinated by the Core are reported in a published manuscript and represent 50 house dust samples from 24 households. The study compares pyrosequencing and the ERMI methodologies for characterizing molds by relative moldiness, a metric associated with an increase of childhood asthma. The paper illustrates how the two methods complement each other in measuring household mold and characterizing exposure. The data from these studies are being analyzed further to characterize how mold changes with agricultural season and household flooring type.
The Core has been working with the UW Environmental Health Laboratory to develop protocols for cortisol analysis in hair. A total of 54 hair samples were collected and have been analyzed by liquid chromatography tandem mass spectrometry (LC-MS/MS) for cortisol. Further protocol development is in progress for the cortisol analysis as well as an additional metal analysis. The Core also has completed saliva cortisol analysis as part of the stress study.
The Core also has developed protocols for biospecimen real-time analysis for informing the Main NCS study. The goal of this project was to identify and optimize state-of-the-art methods to analyze metabolic responses to environmental exposure using the newest omics field, metabolomics, which may provide a powerful way to search for and identify biomarkers for disease and exposures.
Biostatistics, Modeling and Risk Characterization Facility Core
The Core provides innovative statistical, modeling and risk assessment capabilities in order to interpret results of the Center's research. This core has used high-dimension, innovative statistical models for exposure analysis that allow for successful interpretation and analysis of complex cohort studies. Collaboration with investigators on statistical designs and analysis is the start of an integrated process whereby this Core has improved the initial design and construct of studies to increase their power to detect statistically significant results. Some of the challenges the Core has taken into account when performing analyses include field samples with frequent values below quantification limits, missing data, multiple data collection protocols, combinations of random and fixed effects, repeated measures, and multiple spatial and temporal scales.
Analysis of exposure data from the CBPR Projects' previous cohort and the current Pesticide Exposure Pathways Research Project has focused on using Bayesian Markov chain Monte Carlo methods using multivariate distributions in hierarchical models to understand the relationship between child and adult exposures from the take-home pathway for orchard workers, trends in exposures across agricultural seasons, differences between exposures of farmworker and non-farmworker household exposures, and sources of variability.
The Core has been deeply involved in the design of the field sampling to collect information on the cohort identified in previous Center studies. The Center has extended the time period for characterizing exposures by going into the field earlier than previous studies to include the early spring when different OP pesticides are used, in particular chlorpyrifos (CP). In the previous studies, the first season we collected was the thinning season in spring when dimethyl OP pesticides such as azinphos-methyl (AZ) are primarily used. By including the early spring, we will gain a more complete understanding of the episodic OP exposures of orchard workers and their children in the Yakima Valley.
At present, we have data on concentrations of OPs and other contaminants in dust. In the current study, we collected dust from two different days in each season, the first and last days on which we collect urine, in contrast to previous studies where we collected dust on a single day each season. We also are using a less costly method for collecting the dust using a hand-held vacuum. Our initial analyses show that while we collect less dust with the hand-held vacuum, the amounts of dust and concentrations of OPs in the dust provide consistent samples with correlations of 0.7 to 0.8 between the two days within a season and correlations of 0.4 to 0.5 between seasons. The correlations between seasons are similar to the correlations for OPs we saw in our previous Center studies when we collected dust on a single day in each season using a more expensive high powered vacuum. We also have data on additional pesticides and contaminants in the dust that we are in the process of analyzing.
In the current Center studies, researchers also are characterizing stress exposure through the analysis of the stress hormone, cortisol in the blood, saliva and hair of a subset of women. These analyses will help to determine the exposure to environmental and psychosocial stresses in farmworkers and non-farmworkers. We also have used this study to optimize stress assessment protocols through the integration of cortisol biomarker samples with stress questionnaire data. The Core has developed a biokinetic model of cortisol in order to relate the available cortisol biomarkers to estimated peak and average levels of cortisol. The biokinetic model of cortisol was developed based upon literature values and has been tested using blood and saliva samples from the current study. The biokinetic model has performed well, the original publication is already available and the results of our biomarker sample integration have been submitted for publication. Hair cortisol will be added once the sample analysis is complete.
The Core provides an integrated analysis of the results from the multiple studies in the Center. This integration is important for the proper interpretation of the results. In the Center, the studies collect multiple samples at multiple times and seasons from the same set of households, and then multiple analyses are performed on each sample. For the proper interpretation, it is important to have integrated analyses to describe the multivariate joint distribution of these results because all of the characteristics of the data impact the interpretation of individual variables and the relationship between the variables. The integration has allowed us to consider how genotypes for metabolizing enzymes alter the dose-response relationship between cholinesterase inhibition and exposure to OP pesticides.
Community Outreach and Translation Facility Core
The COTC is positioned within the Center to overcome the barriers involved in sharing, interpreting, translating, documenting and archiving data and information in an interdisciplinary and true collaborative research setting. The goal of COTC is to develop, implement and evaluate strategies to translate and apply the scientific findings of the Center into information for the public, policy makers and clinical professionals to use to protect the health of children. The COTC shares membership with the Administrative Core and includes the Centers Faculty Development Investigator/Pediatric Health Specialist, Dr. Karr.
During the reporting period, COTC members have been involved in a variety of exciting outreach and translational activities, on the local, the national, and the international level. Examples include coordinating journal club sessions, hosting an annual regional conference, implementing a webinar series, and developing outreach materials. In the coming year, the team plans also to develop a continuing education course. Because a major aim of the COTC is to engage the Pediatric Health Specialist in clinical translation and needs assessment, Dr. Karr's efforts related to this aim are reported here, and her other pediatric educational activities and pursuits related to her position as Faculty Development Investigator are reported in the Faculty Development Investigator summary.
A key aim of the COTC is the dissemination of research findings and policy implications to not only the broader research community but also government agencies, regulatory bodies, decision makers, the interested public and other stakeholder groups. During the reported period, COTC members were involved in a variety of exciting outreach and translational activities on both the local and national level. In January 2013, Drs. Karr and Faustman attended the Symposium on Cumulative Impacts and Childrens Health. This event was hosted by UC Berkeley and provided updates on scientific findings related to childrens health. Drs. Karr and Faustman assisted with planning this event, which was co-sponsored by the UW CHC and UW PEHSU. Dr. Faustman's presentation entitled "Integrating Temporal and Systems Based Models for Detecting Cumulative Impacts: Lessons from the Pacific Northwest Childrens Health Research Center" discussed models for detecting cumulative health impacts in children.
Another exciting highlight was a collaboration with UW Pediatric Environmental Health Specialty Unit (directed by Dr. Karr). The Center organized and implemented a second annual half-day conference highlighting important contributions to childrens' environmental health from academic or public health agency leaders in the Pacific Northwest. The conference took place on February 26, 2013. The topics covered during this year's conference included effects of wood smoke on children, obesity and childrens health. We were also pleased to be able to present updates on our Centers Return of Results to the community in Eastern Washington. This 2nd annual conference was well attended, drawing over 75 participants from academia, government agencies, clinics, students and the interested public. Feedback for the conference was very positive. The enthusiasm of the audience continues to encourage us to host these annual research conferences, and we anticipate next year's conference to continue this trend.
There are several ways in which Dr. Karr, as the Pediatric Health Specialist, translates Center activities and scientific findings to related health professionals. Primarily, this occurs through educational material in the forms of local presentations, Grand Rounds, participation in public health advisory panels, review article development for clinician and public health professional audiences, monthly journal club, etc. Dr. Karr also participates in review articles, policy development, technical reporting for public health professionals and pediatric clinical providers. Dr. Karr was asked to serve as co-chair for the case management workgroup for the new CDC grant to the Washington State Department of Health for the Washington State Healthy Homes Initiative. In doing so, Dr. Karr oversaw the group that is focused on developing and consolidating case management protocols for children suffering from home-related illnesses such as lead poisoning and asthma.
Future Activities:
>The highlights above illustrate the high volume and quality of the Center's efforts aiming at reducing the adverse effects of environmental pesticide exposures in children. The Center continues to work to understand the mechanisms that define children's susceptibility to pesticides, identify the implications of this susceptibility for health impacts on development and learning, and partner with our communities to translate our findings into risk communication, risk management and prevention strategies. Center researchers continue to work in the lab, in the field, and in the community to bring a unique and successful approach to the study of children's environmental health.
