Exposure Research


EPA's exposure science leads to improved methods, measurements and models to assess and predict exposures of humans and ecosystems to harmful environmental stressors. Environmental stressors can include chemical pollutants, microbes and pathogens, physical agents such as land use, and processes such as alteration of wildlife habitat.

Exposure science also provides the foundation for the development of approaches to reduce these exposures, and safeguard human health and the environment.

Scientists from EPA and community provide students with unique learning experiences during EPA’s 10th Annual Science Day at Y.E. Smith Elementary School

Students filled the hallways of Y.E. Smith Elementary School on Dec. 12 excited to depart from a day of routine schoolwork to learn about science through fun, hands-on activities. Nearly 15 volunteers from the Environmental Protection Agency (EPA) – including scientists, engineers, and staff – along with representatives from the Durham County Soil and Water Conservation District (SWCD) and the City of Durham, joined together for EPA’s 10th Annual Science Day at Y.E. Smith.

EPA scientists participate in Southern Oxidant and Aerosol Study (SOAS)

In one of the largest studies of its kind in North America in decades, EPA is collaborating with 13 other agencies and institutions to learn more about atmospheric chemistry in the summer in the Southeast. The purpose: to improve what we know about how man-made sources of air pollution interact with volatile organic compounds from plants and trees to affect air quality and climate.

EPA's Greenversations Blog | Around the Water Cooler: Perpetual Plastics

Hawaii has become synonymous with tropical sunsets and legendary surfing. And trash. Ocean currents annually deliver 20 tons of refuse, much of it plastics, to the Big Island from the swirling mess called the Great Pacific Garbage Patch. Now, scientists expect added debris from Japan’s 2011 tsunami.

EPA scientists collaborate in development of rapid methods to identify and measure specific pathogens in drinking water

EPA microbiology scientists are working with NanoLogix, Inc. — a U.S.-based company specializing in live-cell rapid diagnostics — to develop new, rapid, sensitive cost-effective methods for detecting and identifying protozoan and bacterial pathogens in drinking water systems. Such methods would be used by epidemiologists to investigating drinking water pathogen outbreaks.

EPA Releases Latest Community Multiscale Air Quality Model

This fall, EPA scientists released a new version of its groundbreaking Community Multiscale Air Quality modeling system. Earlier versions of this state-of-the-science modeling system (known as "CMAQ") have been used by EPA and states for more than a decade to design emission control strategies needed to meet and maintain national air quality standards.(April 26, 2012)
