An overview of the purpose, design, and results of the summer 1981 and winter 1982 ATEOS studies is presented. Daily sampling was conducted during 6-week periods at three urban sites and one rural site: Newark, Elizabeth, Camden, and Ringwood. Inhalable particulate matter was characterized with respect to organic and inorganic composition, the bacterial mutagenic activity of three organic fractions and fine particle mass. The study showed that the IPM fractions of the atmospheric aerosol was composed primarily of EOM (extractable organic matter) sulfate, and crustal material. There were seasonal shifts in the composition, however, with winter time space heating and local motor vehicle traffic appearing to be important factors. Each EOM fraction and the PAH associated with the nonpolar particulate matter increased by a large factor during the winter. The mutagenic activity of the EOM increased, but the types of mutagens present appear to be different in each season. The average SO/sub 4//sup -2/ levels were similar for the two seasons. There were few significant day to day excursions in concentration during the winter. The volatile organic substance measurements showed distinct local source relationships, although benzene levels were fairly constant in all urban locales. Winter time values of VOC (volatile organic compounds) were generally higher than those in the summer. 7 figures, 8 tables. (DP)
