Increasing use of organic chemicals for agricultural purposes has caused great concern in recent years. Rachel Carson (1962) was one of the first to focus public attention on the possible hazards connected with pesticide use. Because of this concern, much work (Dugan et al. 1963, Anonymous 1964) has been done concerning the possible effects and extent of environmental contamination. Studies are being conducted by the federal government (Nicholson 1959, Dugan and Mcfarland 1967, Green and Love 1967, Johnson et at 1967, Sand et al. 1967, Yobs 1967) concerning pesticide concentrations in the population, in food, and in the entire environment of man.
