title: The environmental dynamics of the carbamate insecticide aldicarb in soil and water.
abstract: Aldicarb is a soil-applied systemic pesticide the USEPA is now considering banning in the USA. Aldicarb is fairly rapidly oxidized to the sulfoxide, with a half-life of approximately 7 days in some soils, and much more slowly to the sulfone (pH-dependent with half-lives varying from a few minutes at a pH of > 12 to approximately 560 days at a pH of 6.0). Persistence, carry-over and translocation vary with soil and environmental conditions. Drainage aquifers and drinking water wells are known to be susceptible to contamination, levels of approximately 550 ppb have been recorded. Foods are also known to take up the pesticide; levels of 600 ppb have been found in potatoes.
