Within-microenvironment exposure to particulate matter and health effects in children with asthma: a pilot study utilizing real-time personal monitoring with GPS interface.

Adding same-day cotinine levels as a predictor to models with a pollution variable (either mean PM 1.5 or an exposure event indicator) generally yielded positive but either marginally significant or insignificant relationships between cotinine and health outcomes (uLTE 4 and albuterol) for each microenvironment, and the addition of cotinine did not substantially change the pollutant effects on these health outcomes.
