Abstract |
The document focuses on the sulfur oxides commonly found in the atmosphere--sulfur dioxide, sulfur trioxide, their acids, and the salts of their acids. Further, the document considers the effects of the sulfur oxides in conjunction with other pollutant classes, especially particulate matter, where important synergistic effects are observed. The chemical and physical characteristics of the sulfur oxides are reviewed and the various analytical methods for measuring them in the atmosphere are considered. Aso discussed are the effects of the sulfur oxides on visibility, vegetation, and materials. The toxicological effects of sulfur oxides on animals and on man are considered in separate chapters. Finally, there is a discussion of epidemiological studies that assesses the dose-population response and the response of population subgroups (i.e., children, the elderly, respiratory cripples, etc.) to sulfur oxides and to sulfur dioxide in the presence of particulate matter. The literature has been generally reviewed through June 1968. (Author) |
