Organic Chemistry Research

The Bioactive Chemicals Research Laboratory applies a collaborative transdisciplinary approach to conduct research to minimize the risk to human and aquatic organism health from exposure to contaminants in water supplies.

About the Research The Environmental Chemistry Laboratory Core Technology Team (CTT) as part of the Environmental Health Program develops and applies innovative methods of sampling and analysis to answer critical questions about the occurrence, distribution, fate and transport, and biological exposure of chemical in all environmental matrices (water, air, tissues, sediments, and others).

The Fishing, Hunting, and Subsistence Living Integrated Science Team focuses on contaminant and pathogen exposures in the environment that could impact the presence and vitality of fish and wildlife populations that drive commercial, recreational and subsistence activities such as hunting and fishing. If actual risks are identified this project will inform how to economically and effectively...

Dr. Bethany Kunz received the 2017 Environmental Excellence Award from the Federal Highway Administration (FHWA) for her exemplary research to advance knowledge of the effects of transportation on the natural environment.

The Chesapeake Bay is the largest estuary in the United States and provides critical resources to fish, wildlife and people. For more than a decade, recreational fish species have been plagued with skin lesions and intersex conditions (the presence of male and female sex characteristics in the same fish) that biologists attributed to exposures to endocrine disrupting chemicals (EDCs)...

U.S. Geological Survey (USGS) scientist Dr. Edward T. Furlong has been designated a Thomson Reuters Highly Cited Researcher, ranking among the top 1 percent of researchers from 2003 to 2013 for most cited documents in their specific field (Environment/Ecology). He was listed in Thomson Reuters' "The World's Most Influential Scientific Minds 2015" report.

Estrogens are recognized as modulators of immune responses in mammals, but how these effects might occur in fish was not understood. U.S. Geological Survey (USGS) scientists published findings that fish white blood cells (leukocytes) have specific estrogen receptors (ERs)—a discovery that moves scientists one step closer to understanding the connection between exposure to estrogenic substances and...

U.S. Geological Survey (USGS) scientist Dr. Michael T. Meyer has had a prolific career, publishing 60 journal articles and 45 USGS publications. Mike's publication record has recently led to his designation as a Thomson Reuters Highly Cited Researcher, ranking among the top 1 percent of researchers from 2002 to 2012 for most cited documents in their specific field (Environment/Ecology). He was...

U.S. Geological Survey (USGS) scientists studying a midwestern stream conclude that pharmaceuticals and other contaminants in treated wastewater effluent discharged to the stream are transported into adjacent shallow groundwater. Other mobile chemicals found in wastewater are expected to have similar fates.

Landfill leachate contains a variety of chemicals that reflect our daily activities, U.S. Geological Survey (USGS) scientists concluded as a result of a nationwide study. Landfills are a common disposal mechanism for our Nation's solid waste from residential, commercial, and industrial sources. The scientists found that pharmaceuticals, personal-care products, and other contaminants of emerging...

Research at a 1979 crude oil spill from a ruptured pipeline has exposed and helped to overcome many challenges facing an effective, cost-efficient cleanup of crude oil, U.S. Geological Survey (USGS) scientists have found. The environmental release of crude oil occurred near Bemidji, Minnesota.

Animal manure and biosolids, the solid byproduct of wastewater treatment, often are applied to agricultural crops to provide nutrients for plant growth and to improve the quality of soil. Earthworms studied in agricultural fields where manure and biosolids were applied have been found to contain organic chemicals from household products and manure. Earthworms continuously ingest soils and may...
