Description:
This research brief is a summary of the extensive review and critical analysis of the literature on products of atmospheric photochemical reactions in the lower troposphere, and an assessment of that body of research information. The review is reported separately (Measurements of the Products of Atmospheric Reactions in Laboratory Studies and in Ambient Air - Relationships Between Ozone and Other Products: A Review submitted to Atmospheric Environment). The conclusions reached are as follows: (1) The products other than ozone and nitrogen dioxide in combination occur in ambient air at concentrations approaching or equalling the concentrations of ozone; (2) the other products show the same directional characteristics as ozone in ambient air; (3) the quantitative relationships between these other products and ozone are complex and are different for each product; and (4) the quantitative relationships between these products and precursor hydrocarbons and nitrogen oxides are complex and are different for each product.
