Website: Indoor Air Quality and Personal Exposure Assessment Program

The Web site for the California Air Resources Board's Indoor Air Quality and Personal Exposure Assessment Program offers a wealth of information on air-quality topics, from the general health effects of air cleaners and chlorinated chemicals to the specific air-quality concerns in portable classrooms. Most notably, the AB 1173 Indoor Air Quality Report offers comprehensive coverage of the sources of indoor pollutants and their effects on human health, insight on existing regulations and industry practices, and details on cleaner-air options for homes, schools, and commercial buildings.
