Measuring the Bioenergetic Effects of 1,2-Naphthoquinone Exposure on Human Lung Macrophages Using Seahorse Extracellular Flux Analyses (PRESENTATION)
Exposure to ambient particulate matter (PM) is one of the leading causes of morbidity and mortality in humans. Quinones are organic PM components that induce inflammatory responses through redox cycling and electrophilic attack. 1,2-naphthoquinone (1,2-NQ) has previously been sho...
Modified HWBI Model(s) Linking Service Flows to Well-Being Endpoints: Accounting for Environmental Quality (PUBLISHED REPORT)
This report describes an approach for modifying ORD’s Human Well-Being Index (HWBI) to increase its utility by introducing a composite index developed independently of the HWBI effort. Using ORD’s Environmental Quality Index (EQI), this research examines the potential...
Hospital visits for gastrointestinal Illness after a major water main break in 2010 (PRESENTATION)
Background/Aim
Water main breaks can occur due to the stresses of an aging infrastructure and changing climate. Water main breaks are a public health concern because they can cause pressure transients (specifically, abrupt decreases in water pressure/flow in the pipeline), which ...
Environmental Public Health Research at the U.S. Environmental Protection Agency – Addressing Community Exposures and Outcomes from One Researcher’s Perspective (PRESENTATION)
The U.S. Environmental Protection Agency’s (U.S. EPA) mission is to protect human health and the environment. Those not familiar with U.S. EPA’s mission often do not realize that U.S. EPA is a public health agency. In this presentation, Dr. Danelle Lobdell will provid...
Update for Chapter 5 of the Exposure Factors Handbook: Soil and Dust Ingestion (PUBLISHED REPORT)
This update includes new information on soil and dust ingestion that has become available since the <em>Exposure Factors Handbook: 2011 Edition</em> was released. The recommended values have also been revised, as needed, to reflect the new information. This chapter explains the ...
Exposure Factors Handbook - Update (2009, External Review Draft) (PUBLISHED REPORT)
The mission of National Center for Environmental Assessment (NCEA) of EPA's Office of Research and Development is to provide guidance and risk assessments aimed at protecting human health and the environment. To accomplish this mission, NCEA works to develop and improve the mode...
Estimates of Water Ingestion for Women in Pregnant, Lactating and Non-Pregnant and Non-Lactating Child Bearing Age Groups Based on USDA's 1994-96, 1998 Continuing Survey of Food Intake by Individuals (Journal Article) (JOURNAL)
Women in the child bearing age of 15 to 44 years and, in particular, pregnant and lactating women in this age cohort are considered a sensitive subpopulation when assessing risk from ingestion of contaminated water because ingested contaminants may pose a risk not only to the mot...
The Multi-Sector Sustainability Browser (MSSB): Planning and Developing Sustainability Initiatives Affecting Land Use (PRESENTATION)
The United States Environmental Protection Agency (EPA) Sustainable and Healthy Communities (SHC) Research Program develops methodologies, resources, and tools to assist local and regional community planners, community members, and local decision makers in implementing sustainabl...
Land Use. (BOOK CHAPTER)
Land use in the Narragansett Bay Watershed (NBW) is subject to conversion, and these changes influence the Watershed’s hydrologic functions. Changes of natural habitat such as wetlands and forests to urban lands have impacted how water is delivered to rivers and lakes, to g...
Population (BOOK CHAPTER)
Population growth influences many stressors on Narragansett Bay and its Watershed, including all landscape and chemical stressors discussed in other chapters of this report. In numerous ways, population growth affects the condition of the Bay ecosystem, Watershed ecosystem, and h...
Risk Assessment Training Experience (RATE) – University of Iowa Superfund Research Center. (PRESENTATION)
These modules will offer hands-on training in the primary areas of risk assessment (i.e., legal background, hazard identification, dose-response assessment, exposure assessment, and risk characterization) at the University of Iowa Superfund Research Program on October 2, 2017. An...
20170907- Computational embryology as an integrative platform for predictive DART (45th Conf of Europ Teratology Society) (PRESENTATION)
Chemical regulation is challenged by the large number of chemicals requiring assessment for potential human health and environmental impacts. For example, the USEPA lists more than 85,000 chemicals on its inventory of substances that fall under the Toxic Substances Control Act (T...
A Cellular Game of Telephone: Trans Tissue Reprogramming of Responses to Toxic Stimuli (PRESENTATION)
Exposure to air pollution is a leading cause of cardiopulmonary morbidity and mortality; however, while these effects outside the lung have been associated with aberrant oxidative stress and inflammation, the underlying molecular mechanisms are poorly understood. We hypothesized ...
Key ecological responses to nitrogen are altered by climate change (JOURNAL)
Here we review the effects of nitrogen and climate (e.g. temperature and precipitation) on four aspects of ecosystem structure and function including hydrologic-coupled nitrogen cycling, carbon cycling, acidification and biodiversity.
Provisional Peer-Reviewed Toxicity Values for p-Toluic acid (CASRN 99-94-5) (ASSESSMENT DOCUMENT)
PPRTVs are toxicity values derived for use in EPAs Superfund program when a value is not available in the IRIS database. Superfund site managers use PPRTV in decision making for waste site clean ups. This is a PPRTV for p-Toluic acid.
A Laboratory Comparison of Emission Factors, Number Size Distributions, and Morphology of Ultrafine Particles from 11 Different Household Cookstove-Fuel Systems (JOURNAL)
Ultrafine particle (UFP) emissions and particle number size distributions (PNSD) are critical in the evaluation of air pollution impacts on human health and climate change. Residential cookstove emissions are a major source of many air pollutants; however, data on UFP number emis...
Identification of vascular disruptor compounds by a tiered analysis in ebrafish embryos and mouse embryonic endothelial cells (JOURNAL)
