Production and use
DDT has been formulated in multiple forms, including solutions in xylene or petroleum distillates, emulsifiable concentrates, water-wettable powders, granules, aerosols, smoke candles and charges for vaporizers and lotions.[14]
From 1950 to 1980, DDT was extensively used in agriculture — more than 40,000 tonnes each year worldwide[15] — and it has been estimated that a total of 1.8 million tonnes have been produced globally since the 1940s.[1] In the United States, it was manufactured by some 15 companies, including Monsanto, Ciba,[16] Montrose Chemical Company, Pennwalt,[17] and Velsicol Chemical Corporation.[18]
Production peaked in 1963 at 82,000 tonnes per year.[5] More than 600,000 tonnes (1.35 billion pounds) were applied in the US before the 1972 ban. Usage peaked in 1959 at about 36,000 tonnes.[19]
