Scientific information is presented and evaluated relative to the health and welfare effects associated with exposure to ozone and other photochemical oxidants. Though not intended as a complete, detailed literature review, the document covers pertinent literature through 1983 and early 1984. Data on health and welfare effects are emphasized, but additional information is provided for understanding the nature of the oxidant pollution problem and for evaluating the reliability of effects data as well as their relevance to potential exposures to ozone and other photochemical oxidants at concentrations occurring in ambient air. Separate chapters are presented on the following exposure-related topics pertaining to ozone and other photochemical oxidants: properties, chemistry, and measurement; concentrations typically found in ambient air; formation and transport once formed; and nature, source, measurement, and concentrations of precursors. The specific areas addressed by chapters on health and welfare effects are: the toxicological appraisal of effects of ozone and other oxidants; effects observed in controlled, human exposures; effects observed in field and epidemiological studies; effects on vegetation seen in field and controlled exposures; effects on natural and agroecosystems; and effects on nonbiological materials observed in field and chamber studies.
