Impact/Purpose:
The National Exposure Research Laboratory’s (NERL’s) Human Exposure and Atmospheric Sciences Division (HEASD) conducts research in support of EPA’s mission to protect human health and the environment. HEASD’s research program supports Goal 1 (Clean Air) and Goal 4 (Healthy People) of EPA’s 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:
Low-cost sensors ($1 D0-500) represent a unique class of air monitoring devices that may provide for more ubiquitous pollutant monitoring. They vary widely in design and measure pollutants, ranging from ozone, particulate matter, to volatile organic compounds. Many of these sensors provide for continuous air quality measurements and wireless data transmission. However, data quality from such devices is a concern. Three straw-man approaches to improve upon the usability of such measurements were considered as part of the 2013 EPA Air Sensors Workshop. Findings from the breakout devoted to this topic are summarized below. The 2013 EPA Air Sensors Workshop had a primary technologies was the uncertainty of their data, in goal of moving past previous expert discussions on that often no direct means of sensor calibration discovery of low-cost sensor technologies 1,2 to how was being provided by the sensor developer. As data from such sensors could be used to their explained further in this artide, there are a multitude full advantage. One key concern about these of reasons for this lack of what most monitoring experts would consider to be a necessary feature of any air quality sensor (user response calibration).
