Changes in serum hexachlorocyclohexane (HCH) residues in malaria spraymen after short-term occupational exposure.
The use of organochlorine insecticides for public health programs is indisputably necessary in developing countries. Thus, there is a need to evaluate human response to these chemicals under local field conditions. The effects of a short-term, 16-wk exposure to hexachlorocyclohexane has been evaluated and compared in malaria spraymen with and without any previous occupational exposure to this insecticide by measuring the pre- and post-exposure serum hexachlorocyclohexane concentration. A significant increase in original serum hexachlorocyclohexane concentration. A significant increase in original serum hexachlorocyclohexane concentration was observed in subjects on their first occupational exposure (5X), compared to those with previous exposure (3X). All workers reached approximately the same serum levels within 16 wk, regardless of their history of previous exposure.
