Determination of Pesticides and Their Transformation Products in Air

摘要: The atmosphere has been postulated as a major route for the widespread distribution of more persistent pesticides in environment (Risebrough et al., 1968; Woodwell 1971). This supported by growing reservoir data reporting presence residues air samples from areas far removed normal sites application. Risebrough al. (1968), example, found an average concentration DDT-related and dieldrin 7.8 × 10−14 g/m3 dust collected at Barbados 1965–1966. A later study (Seba Prospero, 1971) revealed concentrations aerosol-borne DDT DDE approximately three times higher tradewinds sampled 1968. In recent (Bidleman Olney, 1974) levels 20 10−12 g/m3, 100 those earlier studies, were reported near Bermuda.
