Helping scientists make more accurate air quality forecasts

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.

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)

New EPA report details data sources for studying older adults’ environmental exposures

A new report developed by EPA exposure scientists, "Data Sources Available for Modeling Environmental Exposures in Older Adults," provides a detailed overview of existing sources of information for studying and modeling seniors' exposures to potentially hazardous chemicals and other pollutants. The report also provides a "state of the science" snapshot as of the end of 2009.

EPA scientists to work with Egyptian counterparts on improving water quality

Environmental Protection Agency scientists have signed an agreement with counterparts in Egypt to share research and training materials to help both agencies protect human health from microbiological contamination in drinking water.

EPA exposure scientists present research at 21st Annual ISES Conference

A diverse group of EPA’s exposure scientists will participate in the 2011 International Society of Exposure Science (ISES) Conference. This year’s meeting is held in Baltimore, Oct. 23-27, and will feature symposia, workshops, platform discussions, and poster sessions on topics ranging from nanomaterials to research on air quality near roadways.
