In Veracruz, Mexico, where organochlorine pesticides are sprayed to combat vector-transmitted diseases, paired mother and umbilical blood samples were collected and analyzed for the presence of organochlorine pesticides. The greatest frequency of detection was noted for p,p'-DDE and hexachlorobenzene, followed by beta -hexachlorocyclohexane and p,p'-DDT. Higher concentrations of all pesticides were found in umbilical blood than in that of the mothers. p,p'-DDE was determined to have the highest partitioning coefficient, followed by p,p'-DDT and beta -hexachlorocyclohexane.
