The degradation of two oxime carbamate pesticides, oxamyl and methomyl, was investigated in anoxic solutions containing various metal ions and reducing agents. In reagent-free solutions, these carbamates degrade slowly via base-catalyzed elimination. Rates of carbamate degradation are accelerated by Fe(II)

The concept of B-esterase buffering against anti-cholinesterase (ChE) insecticide toxicity has been extensively researched in mammalian species. Presumably due to relatively low levels of anti-ChE detoxifying enzyme activity in birds, however, avian species are often more susceptible to the toxic

Bunches of 25 g of tomato galled roots containing ca. 270 eggs and juveniles/g of Meloidogyne incognita were buried on 29 September 2001 in gauze bags at the depth of 15, 30 and 45 cm in a sandy loam. The
Acetylcholinesterase (AChE) activity has been used to test the exposure of mollusk bivalves to pesticides and other pollutants. The Pacific oyster Crassostrea gigas is a species with a worldwide distribution, and it has a high commercial value. The use of

In determining benchmark doses for risk assessment and regulation of carbamate anticholinesterase pesticides like formetanate, oxamyl, and methomyl, one needs to quantitate low levels of cholinesterase inhibition. For improved accuracy while using fewer subjects, we developed an assay based on
