The Small Communities - Big Challenges Competition was a ORD and OEJECR sponsored Challenge and Prize Competition that was open to local governments to highlight innovative and inclusive strategies for engaging with rural communities and collaboratively identifying environmental ...

Background: Mechanistic understanding of transient exposures that lead to adverse health outcomes will enhance our ability to recognize biological signatures of disease. Here, we measured the transcriptomic and epigenomic alterations due to exposure to the metabolic reprogramming...

Excess nutrients (nitrogen and phosphorus) in lakes can lead to eutrophication, hypoxia, and algal blooms that may harm aquatic life and people.&nbsp;&nbsp;Some U.S. states have established numeric water quality criteria for nutrients to protect surface waters.&nbsp;&nbsp;However...

Presentation will be delivered at EPA webinar (Innovations in Environmental Science) and at ACS Fall Meeting. Overview of ongoing F3 research. Investigating the impacts of novel PFAS-free AFFF on environmental and human health is necessary to ensure they are safer, sustainable, a...

New chemical formulations are being tested to replace PFAS-containing fire-fighting foams in several applications, including systems designed to protect aviation fuels, weapons, chemical tankers, and large petroleum tanks. The current efforts are focused on identifying and synthe...

Connectivity mapping is a powerful approach for relating chemicals, targets, and diseases using transcriptomic data (Lamb 2007). It assumes that transcriptomic profiles can fingerprint biological states (e.g., target activation, pathway perturbation, etc.) using the universal lan...

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 1.45–148-fold higher than the r...

Antimicrobial resistance (AMR) is a global crisis threatening human, animal, and environmental health. The natural environment, specifically water resources, has been recognized as a reservoir and dissemination pathway for AMR; however, urban karst aquifer systems have been overl...

This is a set of slides to be used in &quot;scrolling slide&quot; fashion during an EPA Networking Session at the National Adaptation Forum (NAF) in St. Paul, Minnesota on Wednesday, May 15th. The session will feature art from the Fifth National Climate Assessment (NCA5) as part ...

In this poster for the National Adaptation Forum 2024, we will identify and categorize literature published in the last 20 years that addresses observed health benefits and burdens of NbS with respect to vulnerable communities experiencing climate change. Using a visual approach ...

INTRODUCTION: Coccidioidomycosis is an emerging fungal infection caused by inhalation of airborne spores of the Coccidioides genus. While Coccidioides immitis has been detected in soils across California, successful recovery of C. immitis from air samples has so far been limited ...

The Oregon Post-Fire Research and Monitoring Collaborative (state and federal natural resource agencies, tribal organizations, universities, industry) formed in fall 2020, to facilitate shared awareness of post-fire research and monitoring, shared learning, development of resourc...

Historic droughts in western states driven by anthropogenic warming have resulted in an unprecedented increase in wildfire frequency and area burned. In the last few decades, fire acres burned in the United States have more than doubled, with concomitant increased risk to human h...

EPA Wildfire Research: Impacts on Air and Water Quality WESTAR-WRAP Spring Business Meeting 2024, Riverside, California Wildland fire smoke impacts millions of people in the United States every year. The EPA&rsquo;s Office of Research and Development is addressing our increasingl...

Per- and polyfluoroalkyl substances (PFAS) are recognized as an urgent public health and environmental threat across the global community.&nbsp; In response, the United States Environmental Protection Agency (US EPA) has developed a PFAS Strategic Roadmap documenting commitments ...

The number of gray seals (Halichoerus grypus) observed along the United States Northwest Atlantic region has been increasing for decades. These colonial animals often haul-out on beaches seasonally in numbers ranging from a few individuals to several thousands. While these larger...

Historical deposition of nitrogen (N) and sulfur (S) over the Eastern United States has impacted ecosystem structure and function. The potential for recovery of ecosystems is relatively uncertain, with deposition paired with future climate change contributing to this uncertainty....

Variations in stratospheric ozone and changes in the aquatic environment by climate change and human activity are modifying the exposure of aquatic ecosystems to UV radiation. These shifts in exposure have consequences for the distributions of species, biogeochemical cycles, and ...

As U.S. Environmental Protection Agency launches research to advance topics at the intersection of community, climate, health, and nature, we are inviting local decision-makers, city planners, community leaders, NGOs, academics, and private sector experts that are attending the c...

Poster presentation at SOT 2020 associated with abstract {All-Ages Lead Model (AALM) Batch Submission Module: A New Tool for Streamlined Human Lead Toxicokinetic Simulations} in STICS (ORD-035233)

Stream macroinvertebrate assemblages are shaped by natural and human-related factors that operate through complex hierarchical pathways. Quantifying these relationships can support stream ecological assessment. We applied a structural equation modeling framework to evaluate hypot...

Difficulty in diatom species identification and nomenclature can lead to major inconsistencies in taxonomic datasets. These inconsistencies may hinder the use of diatoms in large-extent bioassessments such as the U.S. Environmental Protection Agency&rsquo;s (U.S. EPA) National Aq...

This is a presentation to the Federal-State Toxicology Risk Analysis Committee (FSTRAC) on the development of the ORD Human Health Toxicity Values for PFPrA assessment.&nbsp; It frames the need and problem formulation, process, results, and conclusions.&nbsp;

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...

Mechanistic evidence can play a critical role in human health hazard risk evaluation. New approach methodologies (NAMs) can provide mechanistic data in support of weight of evidence (WoE), particularly for data poor chemicals. While NAMs have provided valuable evidence in support...
