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...

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...

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

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...

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...

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

New approach methodologies (NAMs) are being evaluated for their utility to inform developmental neurotoxicity (DNT) hazard instead of using animals. This work compares predictive models for DNT using DNT NAMs data. The dataset comprised 200 chemicals screened in 17 DNT assays wit...

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...

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...

Career Day at East Cary Magnet Middle School

Brief overview of Earth Observation science and water quality for middle to high school age children.

Concern over exposure to and potential health effects of per- and polyfluoroalkyl substances (PFAS) continues to increase as more is learned about their environmental persistence and human bioaccumulative potential. With PFAS estimates ranging to over 10,000, the limited exposure...

Climate change presents cascading and compounding threats to low-income and underrepresented communities, increasing the need for equitable resilience planning. However, many local governments face challenges incorporating community voices with resilience and vulnerability data i...

Before the era of fossil fuel use, water provided power for industrial processes in the USA through a ubiquitous network of dams and mills. This infrastructure was constructed concurrently with widespread deforestation and sedimentation during the 18th through 20th centuries caus...

The increasing trend in the frequency and intensity of extreme precipitation events and associate flooding has been well documented within the Southeastern U.S. using the historical climate records. Studies also describe dramatic ecosystem responses to extreme events with a plaus...

Enhanced Aquifer Recharge (EAR) is the process of enhancing the natural conveyance of water into the subsurface to augment water supplies. Karst geology offers a natural mechanism for recharge and covers 20% of the U.S. land surface. The potential impacts to groundwater flow foll...

Neurite outgrowth is an important precursor to synapse formation and assays for neurite outgrowth are part of an in vitro battery (IVB) of assays for developmental neurotoxicity screening (DNT). This battery of assays evaluates chemical effects on key neurodevelopmental processes...

Presentation for the AWMA Science of PFAS Conference on characterizing PFAS thermal treatment using online mass spectrometry. In this presentation previously published results from EPA's Rainbow furnace will be discussed to provide context on formation of products of incomplete c...

In urban systems, a wide variety of processes, including increasing impervious surface cover, road salt application, sewage leaks, and weathering of the built environment, contribute to novel chemical cocktails that are comprised of metals, salts, nutrients, and organic matter. D...
