Variations in serum concentrations of selected organochlorines among delivering women in Argentina. The EMASAR study
The EMASAR study is the first study to describe the body burden of OCs in Argentinian women after delivery. In total, 698 maternal serum samples from Salta (n ¼ 498) and Ushuaia (n ¼ 200) were collected in 2011–2012 and analyzed for a total of 7 polychlorinated biphenyls (PCBs) and 12 pesticide-rela...

After controlling for age, parity and heritage (born in the province or migrated there from other regions of Argentina), concentrations of p,p0 - DDE, p,p0 -DDT, b-HCH and all PCBs were significantly higher in Salta natives compared with Ushuaia natives or migrants (p # 0.010).
