Atmospheric chemistry: Scientific basis for sound health-protective and cost-effective air pollution control strategies
- Univ. of California, Irvine, CA (United States)
The validity of risk assessments for airborne toxics, and the effectiveness of associated risk management decisions, clearly depend on the accuracy of the data bases employed to estimate human and/or ecosystem exposures. Three current examples are used to illustrate the necessity of including in today`s risk assessments not only total emissions and ambient levels of specific primary pollutants, but also their reaction products: (1) indoor NO{sub 2} and gaseous HONO; (2) conversion of {open_quotes}non-toxic{close_quotes} polycyclic aromatic hydrocarbons to powerful bacterial mutagens; and (3) the conversion in polluted air of a {open_quotes}safe{close_quotes} pesticide, used to eradicate a major agricultural threat, to a more toxic compound to which hundreds of thousands of Southern Californians have been exposed. The pressing need for fundamental research on the atmospheric chemistry of such diverse classes of pollutants and the health effects of their reaction products is discussed.
