Exposure Assessment for Agricultural Chemicals

  • David J. Severn
Part of the Basic Life Sciences book series (volume 6)


Pesticides are toxic chemicals that are deliberately introduced into the environment to achieve control of pests. For agriculture, these pests include insects, mites, and nematodes which damage growing crops, weeds which compete for nutrients and decrease the value of the harvest, and fungi which cause plant diseases. The Federal Insecticide, Fungicide, and Rodenticide Act specifies that pesticides may be registered for use if that use will not cause unreasonable adverse effects on man or the environment. The potential for adverse effects on man is, of course, determined by both the Inherent toxic properties of the pesticide and the extent of exposure to the pesticide. Thus an assessment of exposure is fully as important as the toxicological evaluation of a pesticide in making judgements about the overall risk of pesticide use.
