The town of Chapaevsk in the Samara region remained one of the most notorious hotspots of dioxin pollution in Russia for many years. The levels of dioxins and other persistent organic pollutants (POPs) content in blood and breast milk of the town residents have been monitored since 2003. A longitudinal study of effects of dioxin pollution on physical and sexual development of boys has also begun in 2003. Levels of dioxins and POPs content in blood were measured annually in a cohort of 516 boys. This study documented a relationship between the POP levels in blood and the distance between the residence of the subjects and the source of the dioxin pollution. The POP content levels in blood were higher for the children who received breast milk (TEQ2005 = 24.5; 95 % CI 20.5 - 28.6) than for the children who received artificial feeding (TEQ2005 = 19.1; 16.5 - 22.1). The lower levels of dioxins and PCBs content were observed in the blood of the boys with higher BMI. The higher levels of POPs content in blood were observed among the boys whose families had vegetable gardens (TEQ2005 = 24.5; 23.6 - 27.3) compared to those whose families did not have gardens (TEQ2005 = 20.6; 18.9 - 22.4). The researchers observed correlations between the indicators of the boys physical development and the levels of dioxins and PCB content in their organisms. The levels of POPs content in the blood of the boys varied greatly from very low to very high, but the median levels were considerably higher than those observed in Europe and the USA. |
