Evaluation of Elm and Speck Sensors
Williams, R., A. Kaufman, T. Hanley, J. Rice, AND S. Garvey. Evaluation of Elm and Speck Sensors. U.S. Environmental Protection Agency, Washington, DC, EPA/600/R-15/314, 2015.
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.
Particulate matter (PM) is a pollutant of high public interest regulated by national ambient air quality standards (NAAQS) using Federal Reference Method (FRM) and Federal Equivalent Method (FEM) instrumentation identified for environmental monitoring. The US EPA has been evaluating emerging PM sensor technologies that might provide benefit to citizen scientists and the scientific community-at-large. Such technologies are rapidly expanding, and new versions of sensor devices previously examined by the US EPA are released by manufacturers. The results described here represent an examination of two such examples involving the Creative Labs Speck and the PerkinElmer Elm sensors.
