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 inspires high school students through organization and participation in climate change workshop
EPA atmospheric scientist Tanya Otte struck a pose to show off her modeling skills before giving a presentation on atmospheric modeling to a group of high school students during a weeklong climate change workshop held at EPA’s Research Triangle Park (RTP) facility June 10-13.
EPA scientists collaborate with NASA on multi-year DISCOVER-AQ study to improve ability to measure and forecast air quality 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 collaborates with Durham County, N.C. on Village Green Project
EPA scientists are partnering with Durham County, N.C., on the Village Green Project to increase air pollution monitoring capabilities in communities and provide real-time air pollution measurements at lower cost and maintenance.
EPA co-sponsors successful workshop to empower citizen scientists to protect stream biodiversity
EPA scientists collaborated with Cincinnati Green Umbrella, Northern Kentucky University, Northern Kentucky Vision 2015, and the Confluence Water Technology Cluster to sponsor a workshop focused on technology development goals to advance citizen-based monitoring for the protection of stream biodiversity.
EPA scientist helps advance water quality assessments of streams and rivers in Argentina
EPA scientist, Dr. Joseph Flotemersch, didn’t expect to make his own sampling nets out of bamboo and scrap metal during a trip to Argentina where he conducted field work and delivered workshops on the bioassessment and monitoring of rivers and streams.
EPA co-sponsors workshop to identify current needs and innovative solutions for rain and stormwater collection and use for non-potable applications
EPA is collaborating with Duke Energy, Cincinnati Regional Chapter of the U.S. Green Building Council, Cincinnati Green Umbrella, and the Confluence Water Technology Innovation Cluster to sponsor a workshop to identify innovative technologies for harvesting and using urban rain and stormwater for non-drinking purposes.
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.
Scientists evaluate air sensors developed during EPA’s Air Sensor Evaluation and Collaboration Event
On September 11 and 12, app and sensor developers from across the U.S. and select European countries gathered at the EPA’s Research Triangle Park (RTP) facility for initial discussions on laboratory evaluations of their air monitoring devices.
National Research Council releases report on Exposure Science in the 21st Century commissioned by EPA and NIEHS
Recognizing that exposure science is a key component for providing the best public health and ecosystem protection, EPA has taken several steps to ensure that the science and research that informs Agency decisions keeps pace with current and emerging environmental issues.
New Testing Methods for Arsenic and Lead in Soil
EPA scientist Karen Bradham, Ph.D., and her research partners are working on inexpensive methods for assessing arsenic levels as a means to improve human exposure estimates for soil arsenic and lead.
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)
