Impact/Purpose:
The National Exposure Research Laboratory (NERL) Human Exposure and Atmospheric Sciences Division (HEASD) conducts research in support of EPA mission to protect human health and the environment. HEASD research program supports Goal 1 (Clean Air) and Goal 4 (Healthy People) of EPA strategic plan. More specifically, our division conducts research to characterize the movement of pollutants from the source to contact with humans. Our multidisciplinary research program produces Methods, Measurements, and Models to identify relationships between and characterize processes that link source emissions, environmental concentrations, human exposures, and target-tissue dose. The impact of these tools is improved regulatory programs and policies for EPA.
Description:
What are “Biosolids”?- “Biosolids” are what remains after WWTP processing Sewage sludge probably a more accurate term - Could contain anything that comes down the pipe to the WWTP, varies greatly depending on community type, industry effluents, plant design and operation- 503 regulations cover pathogens, nutrients, and metals but need to be reevaluated and updated to deal with whole groups of persistent organic pollutants that were not considered in when established in 1993, e.g., perfluorinated compounds, fire retardants, plasticizers…
