Presentation to Duke University, Toxicology &amp; Environmental Health Seminar

These are slides to give an overview of applied NAMs for hazard, using the example workflow of performing an endocrine assessment using ToxCast data and models, followed by calculation of a bioactivity:exposure ratio. Then, examples of applied bioactivity:exposure ratios or point...

Background and Purpose: Per- and polyfluoro-alkyl substances (PFAS) are a large and diverse class of organic chemicals in which all (per-) or some (poly-) carbon&ndash;hydrogen bonds have been replaced with carbon&ndash;fluorine bonds. PFAS are commonly found in human tissues. S...

In drinking water distribution systems, including premise plumbing, dissolved oxygen (DO) and free chlorine (FC) are common oxidants and ductile iron (DI) and copper (Cu) are commonly used pipe materials. Microelectrodes are a tool that have been applied in previous corrosion res...

This presentation is to the Research Area Coordination Team (RACT) for the Safe and Sustainable Waters Research program. This work contributes to SSWR Subproduct 404.3.2 Applying forecasted data to better understand, quantify, and anticipate the social and environmental justice i...

The global nitrogen science-policy community lacks a holistic framework for assessing nitrogen (N) impacts on food production, ecosystems, health, and climate. This results in reduced effectiveness and societal welfare benefits in addressing N challenges and creates the potential...

Bioaccessibility and relative bioavailability of As, Cd, Pb and Sb was investigated in 30 legacy gold mining wastes (calcine sands, grey battery sands, tailings) from Victorian goldfields (Australia). Pseudo-total As concentration in 29 samples was 1.45&ndash;148-fold higher than...

Presentation to HEEDS EDC-North Carolina Working Group Fourth Annual Scientific Meeting

Communities across the United States are enduring, often unexpectedly, the effects of extreme events, such as excessive heat, prolonged droughts, extreme floods, and wildfires. In places where contaminated sites and waste management facilities are also present, communities must c...

One in 33 babies born in North Carolina (NC) are diagnosed with any birth defect. Little has been done to examine the association between community-level risk factors and birth defects. The objective of this study was to estimate the association of census-tract level neighborhood...

Stable isotope ratios integrate, indicate, record, and trace fundamental processes in hydrology and ecology.&nbsp; Stored within the atoms of samples, stable isotope ratios of specific elements unlock stories about ecological processes that impact water quality and quantity.&nbsp...

This research investigated the in-situ decay rates of four human wastewater-associated markers (Bacteroides&nbsp;HF183 (HF183),&nbsp;Lechnospiraceae&nbsp;Lachno3 (Lachno3), cross-assembling phage (crAssphage), pepper mild mottle virus (PMMoV) and three enteric viruses (human aden...

Many studies suggest that environmental exposures, including air pollution, are associated with adverse birth outcomes. A growing body of research reports that neighborhood greenery is associated with reduced odds of adverse birth outcomes. We examine the associations between PM2...

Increasing water shortages and aging infrastructure have broadened interest in using alternative source waters for a range of end uses. Developing fit-for-purpose treatment approaches requires consideration of both the proximal risks of reuse-related exposures and the more distal...

The Bayesian network (BN) session at the SETAC North America 44th Annual Meeting was conducted for the sixth consecutive year. Since its inception in 2018 during the SETAC North America annual meeting in Sacramento, the BN session has grown into a multi-faceted platform for the p...

This is a presentation on the effects of wildfire on air and water quality for the ACE webinar series

As the risks of climate change impacts become more apparent and more severe, communities need ways to plan, adapt, and transform in order to increase resilience. Disasters cause widely disparate impacts on communities and populations with differential vulnerability, making necess...

This poster, &ldquo;Building Factors Influencing Indoor Air Quality During Wildfire Smoke Events,&rdquo; provides an overview of the results and significance of a field study conducted in Missoula County, MT examining indoor air quality in public and commercial buildings during a...

Communities across the world are experiencing a myriad of impacts from intensifying extreme heat, flood, drought, and wildfire events due to climate change. Further impacts can be experienced due to nearby contaminated sites and waste management facilities that are either activel...

Read-across is a data-gap filling technique utilised to predict the toxicity of a target chemical using data from similar analogues. Read-across is predominantly performed as part of an expert-driven assessment which can impeded broad acceptance. Data-driven approaches such as Ge...

Background and Purpose: Health effects of inhaled smoke from military burn pits include increased incidences of cardiopulmonary diseases, sinonasal disease, and cancers of the nervous system. Burn pit smoke is a complex mixture of particulate matter (PM), volatile organic compoun...

Journal article submitted to EcoHealth - (Abstract) - Lyme disease (LD) is the most common vector-borne disease in the United States (U.S.). This paper assesses how climate change may influence LD incidence in the eastern and upper midwestern U.S., and the associated economic bur...

Permafrost soils store &sim;50% of terrestrial C, with Yedoma permafrost containing &sim;25% of the total C. Permafrost is undergoing degradation due to thawing, with potentially hazardous effects on landscape stability and water resources. Complicating ongoing efforts to project...
