Organophosphorous Pesticides: Their Effects on Biosentinel Species and Humans. Control and Application in Chile

The environment is negatively affected by the increasing accumulation of both natural and man-made waste and by-products. Organophosphorous pesticides -malathion, diazinon and methamidophos- are used worldwide in pest control. The aim of this report is to review the effects of organophosphates on th...
