Chemicals degraded by WRF include pesticides such as organochlorines DDT and its very toxic metabolite DDE [8, 9] and organophosphate pesticides such as chlorpyrifos, fonofos and terbufos [10] polychlorinated biphenyls (PCBs) of different degrees of chlorine substitution [11-13], some even to mineralization [14, 15] diverse polycyclic aromatic hydrocarbons (PAHs) in liquid media and from contaminated soils or in complex mixtures such as creosote [16-18] components of munition wastes including TNT and its metabolites DNT [19-23], nitroglycerin [24] and RDX [25].

Chemical/Physical. Terbufos and its degradation products, terbufos sulfoxide and terbufos sulfone, followed first-order disappearance in natural, sterilized natural, and distilled water at 20 °C. In natural and distilled water, the sulfoxide and sulfone had half-lives of 18-40 and 280-250 d, respectively. Terbufos disappeared more rapidly (half-life = 3 d) (Bowman and Sans, 1982). The hydrolysis half-lives of terbufos in a sterile 1% ethanol/water solution at 25 °C and pH values of 4.5, 6.0, 7.0, and 8.0, were 0.29, 0.28, 0.28, and 0.32 wk, respectively (Chapman and Cole, 1982). 

Lee et al. (1999a) reported that terbufos sulfoxide is the major product of sunlight photolysis of terbufos. Terbufos sulfoxide was reported as a minor product. In distilled, deionized, unbuffered water, the experimental photolysis half-life was 56 min.
