title: Organochlorine pesticide residues in human blood samples collected from Haryana, India and the changing pattern.
abstract: Blood samples were collected during August 1992 and August 2002 from various hospitals of Haryana state and analyzed for the presence of HCH and DDT residues and the change in concentration of pesticide residues was calculated in terms of % reduction. The study revealed that the mean residue levels of total HCH in human blood samples have declined by 87.6% while those of total DDT have decreased by 98.9% during a gap of 10 years. The obtained results reveal that during 1992 p,p'-DDT was the major component with the mean value of 6.125 mg/L followed by p,p'-DDE, γ-HCH, α-HCH and β-HCH while in 2002, β-HCH and p,p'-DDE were comparable with mean value of 0.053 and 0.052 mg/L, respectively followed by p,p'-DDT, α-HCH and p,p'-DDD.
