EPA's National Exposure Research Laboratory (NERL) is comprised of several divisions with diversified research specialties. NERL conducts research and development that leads to improved methods, measurements and models to assess and predict exposures of humans and ecosystems to harmful pollutants and other conditions in air, water, soil, and food.
A Conceptual Framework for the U.S. EPA's National Exposure Research Laboratory provides a foundation for addressing NERL's research mission and its scientific leadership goals. Read more about the exposure framework document ...
Scientists from the EPA's National Exposure Research Laboratory were honored recently with Scientific and Technological Achievement Awards for research contributions focused on understanding children's exposure to chemicals in everyday environments.

Singer Joni Mitchell crooned, “They paved paradise and put up a parking lot.” Today the presence of thousands of parking lots in the United States illustrates just one example of how human-induced change can negatively affect the benefits — or ecosystem services — provided by the environment that we have come to rely upon to live.
NERL has compiled a database listing citation information for literature related to PPCPs. (updated May 2009)
NERL has prepared a document on scientific and ethical approaches for observational exposure studies through recommendations from an expert panel, public comment, and external peer review.
