During the fall of 1990, a large-scale field monitoring program for personal exposure to PM{sub 10} was conducted in Riverside, California by Research Triangle Institute, Harvard School of Public Health and the Acurex Corporation. The pilot PTEAM (Particle Total Exposure Assessment Methodology) study, co-sponsored by the EPA and the California Air Resources Board, collected personal exposure data on PM{sub 10} and elemental mass for 175 residents of Riverside. During this study, indoor and outdoor concentrations of PM{sub 10}, PM{sub 2.5}, and elements were also collected at participants` homes; PAH and phthalate data were collected in a subset of 125 homes. Twelve-hour recall time-activity diaries and questionnaires regarding exposure to ETS and other sources of particles, PAHs and phthalates were also obtained and later uses in exposure modeling. Measurements showed that most PAHs and phthalates had high detection rates: 60--100%. Aside from smoking, analysis did not indicate cooking, spraying, house cleaning activities or proximity to busy roadway as possible sources of PAHs or phthalates. Both physical and empirical statistical models were used to estimate the contributions of outdoor sources, cigarette smoking, and other indoor sources.
