Scientific and Technical Assessment Report on particulate polycyclic organic matter (PPOM)
This report is a review and evaluation of the current knowledge of particulate polycyclic organic matter in the environment as related to possible deleterious effects on human health and welfare. Sources, distribution, measurement, and control technology are also considered. Results of an extensive literature search are presented. Experiments have shown a number of polycyclic organic compounds to be carcinogenic in animals. Although these same compounds have not been proven to be carcinogenic in humans, evidence strongly suggests that they may contribute to the ''urban factor''. In American males, the urban lung cancer death rate is about twice the rural rate, even after adjustment for differences in smoking habits. Evidence suggests significant differences between specific urban areas across the United States. The bulk of the available data is in terms of benzo(a)pyrene; so this compound has been used as an index on particulate polycyclic organic matter. Average seasonal concentrations of BaP in the ambient atmosphere range from less than 1 ng/m/sup 3/ in nonurban areas to a maximum of 50 ng/m/sup 3/ in rural areas.
