Polycyclic aromatic hydrocarbons (PAH) commonly occur in wastes from pyrolysis of biogenic fuels. Because some PAH are known carcinogens, understanding of their environmental behavior and persistance is critical to determining their potential hazard to man. While many processes may remove or transform PAH in aquatic ecosystems, several may be particularly important in determining the fate of PAH in most systems. Anthracene was selected as a representative PAH due to its intermediate molecular and its lack of carcinogenicity. Rates of photolysis, hydrolysis, volatilization, and microbial degradation of anthracene were measured under different environmental conditions using fluorimetric and radiotracer techniques. Equilibrium constants for processes such as sorption and bioaccumulation were also determined.
