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.

EPA scientists collaborate with NASA to improve view of air pollution from space
EPA exposure scientists are collaborating with NASA on a multiyear study to help scientists better understand how to measure and forecast air quality globally from space. The NASA-led mission — known as “DISCOVER-AQ” — stands for Deriving Information on Surface conditions from COlumn and VERtically resolved observations relevant to Air Quality.

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)
