Abstract
Equations are derived that describe the direct photolysis rates of pollutants in the aquatic environment. The equations translate readily obtainable laboratory data into 'half-lives' for photolysis under sunlight. Photolysis half-lives are calculated as a function of season, latitude, time-of-day, depth in water bodies, and ozone layer thickness. Experimental verification of the computed half-lives is presented.
