Change in Knowledge After Receiving Personal Air Pollution Results

Personal exposure to air pollution results from the interaction of individual time-activity patterns with levels of air pollution that vary over time and space. The increasing use of personal monitors capable of measuring geo-located and real-time air pollution in epidemiologic studies requires novel human subject considerations. Reporting individual exposure data back to participants is considered best practice in environmental health research using biomonitoring data and is beneficial to both study participants and researchers. The investigators believe that providing individual results of personal air monitoring may be more informative than biomonitoring data given the potential to increase participants' awareness of their exposure, identify specific locations and times of elevated exposures, and inform behavioral changes to decrease exposure and risk of adverse health outcomes.
