Study of POPs levels in the breast milk of women-residents of Chelyabinsk Oblast (Karabash) and Tyumen Oblast (Tobolsk).
The project is aimed at reducing adverse impacts of POPs on health of local residents, (particularly children), residents of the impact zone of Karabash copper enterprise, Cheliabinsk region, and Tobolsk oil and chemical enterprise in the Tumen region, Russia. In the course of the project implementation, human contamination by dioxins, furans and PCBs was studied. Samples of breast milk of nursing mothers of Karabash and Tobolsk cities were collected with application of the WHO methodology. The quantitative chemical analysis of 17 toxic polychlorinated dibenzo-p-dioxins and dibenzofurans was carried out using US EPA 16 13 method as well as 12 toxic PCBs using US 166 8A method. The study used a socio-medical screening of breast milk donors and their families, as well as conduction of multi-factor analysis for further development of a model of POPs circulation in the population of Karabash and Tobolsk cities residents. Average levels of dioxins / furans in Karabash were 19.99 WHO - TEQ pg/g fat and in Tobolsk, 9.56 WHO - TEQ pg/g fat. Average levels of PCBs were 12.6 WHO - TEQ pg/g fat and 17.9 WHO - TEQ pg/g fat in Karabash and Tobolsk respectively.
