In the United States, the Clean Air Act requires the Environmental Protection Agency (EPA) to establish National Ambient Air Quality Standards (NAAQS) and to monitor six common air pollutants. For NAAQS compliance, air quality instruments must adhere to stringent sampling, siting...

Taxonomic data are the foundation of bioassessment and much basic and applied research. Difficulty in morphological species identification, evolving and varying taxon concepts, and nomenclatural changes can lead to significant inconsistencies in taxonomic datasets across analysts...

Lead (Pb) and arsenic (As) contamination of soils is widespread in the United States and is an important source of exposure in young children. Early life exposure to metal(loid) contaminants has serious and long-lasting effects on health, making mitigation a critical public healt...

In the US there are over 20,000 abandoned hardrock mines that may present risks to human health or the environment from long-term exposure to harmful substances. One site is the Formosa mine Superfund site located in Oregon, US. The site lacks plant cover due to phytotoxic tailin...

A PowerPoint presentation created by the National Program Manager for Regional Laboratories to present to the Association of Public Health Laboratories.

The Regional Monitoring Networks (RMNs) are a collaborative, volunteer effort to collect comparable long-term monitoring data at targeted sites nationwide to detect changes over time. Six Northeast states have participated in the stream RMN since it was first piloted in the North...

Per- and polyfluoroalkyl substances (PFAS) are compounds found in many consumer and industrial products with ubiquitous spread in environmental matrices. While there is evidence that some PFAS, notably perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), cause d...

Anatoxin-a (ATX) is a cyanobacterial neurotoxin produced in freshwater lakes, streams, and reservoirs both in planktonic and benthic blooms. It is a potent and irreversible nicotinic acetylcholine receptor (nAChR) agonist that causes central and peripheral effects while it is the...

EPA in partnership with 10 federal, state, local, and tribal organizations sponsored a science-based challenge to encourage development of new, effective, low-cost approaches (termed &quot;Solutions&quot;) to remove PM5 from indoor air, particularly high concentrations related to...

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...

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 Adaptation Organon (AO) for Resilient Natural Resources is a web-based interactive framework and information resource for integrating climate change and other environmental information into project and program planning. It is being used by the U.S. Environmental Protection Ag...

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

Above ground storage tanks/terminals provide an essential link in the transportation of fuel between national infrastructure (e.g., pipelines) and local distribution points (e.g., gas stations). Volatile components of refined gasoline/fuels (including ozone precursors and air tox...

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...

Per- and polyfluoroalkyl substances (PFAS) are a diverse class of persistent contaminants associated with a variety of adverse effects and found in aquatic ecosystems worldwide. There is an urgent need for data to assess the ecological risk from the universe of PFAS. Therefore, w...

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...
