Early-life environmental factors can influence later-life susceptibility to cancer. Epigenetic changes serve as promising biomarkers for these latent effects. Previously, we reported that short-term postnatal exposure to dichloroacetic acid (DCA), a byproduct of drinking water ch...

Overview of the EPA's involvement in the Deep Water Horizon Oil Spill. This drives the need for rapid “screening-level” risk assessments using “New Approach Methods” (NAM).

Eight software applications are compared for their performance in estimating the octanol-water partition coefficient (Kow), melting point, vapor pressure and water solubility for a dataset of polychlorinated biphenyls, polybrominated diphenyl ethers, polychlorinated dibenzodioxin...

A major area of growth for “nano-enabled” consumer products have been surface coatings, including paints stains and sealants. Ceria (CeO2) nanoparticles (NPs) are of interest as they have been used as additives in these these products to increase UV resistance. Currently, there i...

Biochar in conjunction with other soil amendments can be used for in situ remediation of metal-contaminated mine spoils for improved site phytostabilization. For successful phytostabilization to occur, biochar must improve mine spoil health with respect to plant rooting plus upt...

this presentation covers an ongoing study at a Cincinnati house, following the progression of lead release from a lead service line with different amounts of stagnation time and water use. This presentation is essentially the same as the talk cleared for AWWA ACE 2017, with some...

Advances in understanding the optics of shallow water environments, submerged vegetation canopies and seagrass physiology, combined with improved spatial resolution of remote sensing platforms, now enable eelgrass ecosystems to be monitored at a variety of time scales from earth-...

Understanding the effects of environmental management strategies on society and the environment is critical for evaluating their effectiveness but is often impeded by limited data availability. In this article, we present a method that can help scientists to support environmental...

The vertebrate zebrafish (Danio rerio) embryo is an emerging model for screening for teratogenic compounds. We aim to understand the developmental toxicity effects of environmental pollutants by using zebrafish embryos to identify compounds that negatively affect neuromasts of th...

Legacy perfluorinated compounds exhibit significant environmental persistence and bioaccumulation potential, which has spawned an ongoing effort to introduce replacement compounds with reduced toxicological risk profiles. Many of these emerging chemical species lack validated qua...

Agricultural land use is a primary driver of environmental impacts on streams. However, the causal processes that shape these impacts operate through multiple pathways and at several spatial scales. This complexity undermines the development of more effective management approache...

UV irradiation is one of the most commonly used wastewater disinfection methods. Significant advantages of using the UV-based disinfection are that it leaves no residual and does not form any disinfection by products (DBPs) in the treated wastewater. However, the high-energy cost...

Bisphenol A (BPA) is commonly manufactured to make polycarbonate plastics and epoxy resins for use in consumer products and packaged goods. BPA has been found in several different types of environmental media (e.g., food, dust, and air). Many cross-sectional studies have frequent...

In managing U.S. estuaries, as well as throughout ocean and coastal governance, there is an increasing call for economic research to inform decisions and to communicate the values of environmental resources to local communities, policy makers, and other stakeholders. Watershed ma...

The ECOTOXicology knowledgebase (ECOTOX) is a comprehensive, curated database that summarizes toxicology data from single chemical exposure studies to terrestrial and aquatic organisms. The ECOTOX Knowledgebase provides risk assessors and researchers consistent information on tox...

Until somewhat recently there was limited awareness about the impact of soils on human health, ecosystems, and economy. Only in the second half of the twenty century the world awaked for the poor condition of soils, and to its several threats (e.g. soil contamination), as well as...

A disjunct population of the annual form of the seagrass Zostera marina that occurred in the upper intertidal zone of Yaquina Bay, Oregon was sampled to determine whether there were differences in recruitment, growth, survivorship and morphology associated with microtopographic l...

Journal Article

The urbanization of the modern community creates large population centers that generate concentrated wastewater. A large expenditure on wastewater treatment has to be invested to make a modern city function without human and environmental health problems. Society relies on syste...

Some current&#8208;use pesticides are chiral and have nonsuperimposable mirror images called enantiomers that exhibit identical physical&ndash;chemical properties but can behave differently when in contact with other chiral molecules (e.g., regarding degradation and uptake). Thes...

The U.S. Environmental Protection Agency (EPA) Engineering Issue Papers (EIPs) are a series of technology transfer documents that summarize the latest information on selected waste treatment and site remediation technologies and related issues. The information is presented in a c...

The facility for the US Environmental Protection Agency&rsquo;s Western Ecology Division (WED) has been involved in environmental toxicology and chemistry research since its inception in 1961 when it was the Pacific Northwest Water Laboratory. Currently, WED is one of four ecolog...

The Environmental Effects Assessment Panel (EEAP) is one of three Panels of experts that inform the Parties to the Montreal Protocol. The EEAP focuses on the effects of UV radiation on human health, terrestrial and aquatic ecosystems, air quality, and materials, as well as on the...

The weathering release rate of base cations&nbsp;(BCw) from soil minerals is fundamentally important&nbsp;for terrestrial ecosystem growth, function, and sensitivityto acid deposition. Understanding BCw is necessary&nbsp;to reduce or prevent damage to acid-sensitive&nbsp;natural ...
