Abstract

Our study examined the performance of the Harvard ozone passive sampler, providing comprehensive evaluation results and investigation of ozone behavior around the human body through a series of chamber and indoor field tests. The results demonstrated excellent agreement between the passive and continuous measurements for both personal and indoor monitoring in an environmental exposure chamber. An ozone concentration gradient around the human body was found, most likely due to depletion and dilution effects. When the passive sampler was attached to a polystyrene backing plate and worn on the chest, ozone depletion on clothing was significantly reduced. Results from additional indoor field tests support those from the chamber study
