Second Addendum to Air Quality Criteria for Particulate Matter and Sulfur Oxides (1982): Assessment of Newly Available Health Effects Information (1986)

This Addendum to the earlier 1982 U.S. EPA document, Air Quality Criteria for Particulate Matter and Sulfur Oxides, evaluates scientific information on health effects associated with exposure to various concentrations of sulfur oxides and particulate matter in ambient air. Although the literature through 1986 has been reviewed thoroughly for information relevant to air quality criteria, the present Addendum is not intended as a complete and detailed review of all literature pertaining to sulfur oxides and particulate matter. Rather, an attempt has been made to focus on the evaluation of those studies providing key information by which to delineate quantitative exposure—effect or dose- response relationships for the subject pollutants.

Although this Addendum is principally concerned with the health effects of sulfur oxides and particulate matter, other scientific data are presented and evaluated in order to provide a better understanding of these pollutants in the environment. To this end, the Addendum also includes discussions of physical and chemical properties of sulfur oxides and particulate matter; ambient air monitoring and related analytical techniques; and the respiratory tract deposition and fate associated with human exposure to the subject pollutants.
