This report presents detailed results from a survey and critical review of existing published literature and reports on indoor air quality (IAQ), ventilation, and IAQ- and building-related health problems in schools, particularly California schools. The findings: (1) identify the most commonly reported building-related health symtoms involving schools; (2) assemble, evaluate, and summarize existing measurement data on key indoor air pollutants most likely to be related to these symptoms; e.g., carbon dioxide, volatile organic compounds, and bioaerosols; (3) assemble and summarize existing measurements of ventilation rates in schools; and (4) summarize information on causes of indoor air quality and health symptom problems in schools. Appendices contain data tables. (Contains 193 references.) (EV)
