1Portions of this paper were presented at the Residues in Foods Conference conducted by the Food Science Department, Michigan State University, East Lansing on March 27–28, 1961.
2First in a series of three review papers on this subject which will appear in this Journal.
Editorial Note: Chlorinated hydrocarbon insecticides have been used to control pests on many plants of economic importance, on livestock and in soil. These uses have led to deposition of this group of insecticides in a host of biological material ranging from tobacco to eggs.
This is the first of three review papers which will provide background information on different materials which have become contaminated and the levels of insecticide residues present. The first paper will discuss contamination of plants and their products; the second, animals and their products; and the third, soil and bodies of water.
