Williams, R., R. Long, M. Beaver, R. Duvall, Sue Kimbrough, E. Thoma, Bill Mitchell, J. Rice, T. Hanley, AND S. Garvey. Observations from Laboratory and Field-based Evaluations of Select Low Cost Sensor Performance. 2014 International Society of Exposure Science, Cincinnati, OH, October 12 - 16, 2014.
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.
• Produces data of known value and highly reliable• Stationary- cannot be easily relocated• Instruments are often large and require a building to support their operation• Expensive to purchase and operate (typically > $20K each)• Requires frequent visits by highly trained staff to check on their operation• Often operate for 10+ years before needing to be replaced
