    ENVIRONMENTAL FATE
    EHC 63 (WHO, 1986; a general review of organophosphorus insecticides). Animals In mammals, following oral administration, elimination is mainly in the form of hydrolysis products in the urine. Major metabolites are fenthion sulfoxide, fenthion sulfone and their oxygen analogues. These metabolites are hydrolysed in further degradation, forming the corresponding phenols. Plants In plants, fenthion is oxidised to the sulfoxide and sulfone, both of which possess insecticidal properties, and to the monodesmethyl compound of fenthion sulfoxide. Further degradation occurs to the sulfone phosphate, which undergoes hydrolysis. Soil/Environment Koc 1500 (Ware, Rev. Environ. Contam. Toxicol., 123 (1992)). In sediment/water system with and without plants, DT50 is c. 1.5 d (O'Neill et al., Environ. Toxicol. Chem., 8, 759-768 (1989)). The degradation of fenthion occurs rapidly under aerobic conditions, forming the metabolites fenthion sulfoxide, fenthion sulfone, followed by the analogous phenol compounds.
