Aquatic sinks, methylchloroform

Aquatic Sinks for Methylchloroform. Methylchloroform distributions in the troposphere have been used to estimate the concentrations of tropospheric hydroxyl radicals (65). The estimates assume that reaction with tropospheric OH radicals is the dominant sink. Aquatic sinks have been ignored. Wine and Chameides (66), however, presented model computations that indicated that hydrolysis and reaction with solvated electrons may be a significant sink for methylchloroform and other halocarbons in the open ocean. 

Photochemical reductions and oxidations in aquatic environments provide sinks or sources for halocarbons. Such photoreactions are an important process in the dissipation of low-volatility halocarbons, such as halogenated agrochemicals, in aquatic environments (reference 9 contains lead references). For example, field studies of Crossland and Wolff (10) demonstrated the rapid dissipation of pentachlorophenol residues by its photoreaction in English ponds. Evidence emerged that volatile halocarbons such as 1,1,1-trichloroethane (methylchloroform) may have significant sinks in the aquatic environment...
