Using Global Positioning Systems (GPS) and temperature data to generate time-activity classifications for estimating personal exposure in air monitoring studies: an automated method(21 page pdf, Elizabeth Nethery Gary Mallach, Daniel Rainham.

Today we review research that looks at the advantages offered by a GPS and a PM2.5 particulate sensor to monitor 70 children and the pollution sources and durations they are exposed to over 10 days. The pollution sources vary between indoors and outdoors, using transit or driving, as well as in proximity to roadside emissions in the large metropolitan area that Montreal is. This approach improves upon the data that can be collected from a personal pollution exposure sensor that only produces the total pollution exposure over a given time period by breaking down the exposure by location. The use of a GPS also precludes the need to keep a diary as well as offering more convenience and accuracy, and possibly an effective way of monitoring larger populations for longer periods- if smart phones with a sensor were used for example..
