Protocol guidelines for the investigations of photochemical fate of pesticides in water, air, and soils

Pesticides represent an increasingly important sort of synthetic chemical introduced into the environment through human activity. A compound is important in environmental chemistry provided it has (or shows evidence of having) the following characteristics (Choudhry et al. 1979a): produced or distributed in large quantity high likelihood of entry into the environment — dispersion tendency (transport) persistence (lack of degradation under biotic and abiotic conditions) bio-accumulation (concentration effects, e.g., in the food chain or by other mechanisms) significant toxicity and related biological effects
