A study of pesticide residues in Michigan's general population, 1968-70.

A study undertaken in Michigan from August 1968 to April 1970 showed that the county of residence was the most significant factor for determining pesticide residue levels in humans. Occupation, sex, and location of residence were also determined to be associated with blood residue levels. Residues of sigmaDDT and dieldrin were greater in persons 45 years or older. No relationships were detected between blood hemoglobin and blood residue values. In general, as the blood levels for glucose, cholesterol, uric acid, and creatinine increased, so did the levels of pesticide residues. However, when all variables were used, no equation could be developed which would reliably predict a blood residue level given these demographic characteristics.
