Study of DDT blood level in a group of workers exposed to pesticides.
Blood levels of DDT, DDE, and other DDT metabolites were determined in a group of workers with previous occupational exposure to DDT as spraymen. The larger part of total DDT was in the form of metabolite DDE, which is thought to be introduced into the human body primarily from external sources. Total DDT blood level was correlated positively with both age and occupational exposure (R = 0.58 and 0.52, respectively), and linear regressions between storage and these variables were demonstrated. Although the storage of these compounds in body fat was not studied, the analysis of covariance showed a significant increase of DDT blood level in the group of workers with longer occupational exposure, which was not dependent on age.
