WALISZEWSKI, Stefan M. et al. Organochlorine pesticide levels in blood serum compared to total blood lipid content. Rev. Int. Contam. Ambient [online]. 2015, vol.31, n.2, pp.155-164. ISSN 0188-4999.

Organochlorine pesticides bioaccumulation models have generally been formulated to predict the bioconcentration and biomagnification of that compounds. Due to the lipophilic properties and persistence, the organochlorine pesticides accumulate in lipid rich tissues which serve as biomarkers of environmental pollution. In human, organochlorine pesticides continuously circulate and equilibrate among body compartments. The objective of the study was to compare the concentration of or-ganochlorine pesticides in blood serum with levels of total blood lipid content. The obtained organochlorine pesticide concentrations were divided in ascending sextants according to the total lipid content. The results reveal that the mean of all organo-chlorine pesticides decreases as the lipid concentration increases. b-HCH shows a decrease of -0.8948 mg/kg, pp'DDE of -0.9195 mg/kg, pp'DDT of -0.090 mg/kg and S-DDT of -0.8814 mg/kg from one to other sextant. The ANOVA test applied to reveal differences among sextants showed significant differences among means for b-HCH, pp'DDE and S-DDT and not significant differences among pp'DDT sextants.
