Objective determination of indoor air quality using passive air samplers and bioassays. Final Report.

This report details the development and field testing of a passive sampler system to collect gaseous and particulate contaminants in indoor air and the evaluation of the collected materials for biological effects using a simple bioassay system. The passive sampler-biossay system is a cost-effective objective method for determining indoor air quality. Field studies of the sampler for gaseous contaminants were carried out at 449 sites distributed among 19 buildings and 11 homes, while field studies of the particulate sampler were carried out at 298 rites disdributed among 9 of the buildings and 6 of the homes.
