title: Cytogenetic study of workers exposed to methyl-parathion.
abstract: When compared with non-exposed controls, a group of pesticide plant workers chronically exposed to methyl-parathion did not show an increased frequency of chromosome aberrations in lymphocyte cultures. Although methyl-parathion increased chromosome aberrations in cases of intoxication, a chronic exposure to small doses in the work place did not seem to produce the same effect.
