RESUMO

The presented research is pioneer in brazil and its relevance is due to the various unmapped possible anthropogenic sources of PCBs, PCDDs and PCDFs, to the occurrence of accidents with chlorinated products exposing brazilian populations and the recent episode related to the presence of such contaminants in feedstuff exported to europe. The main objective of this study was to evaluate the exposure of the general population considering human milk as good indicator. Moreover, the study may subsidize future preventing actions and emission control of these pollutants to the environment as an effective manner to minimize human exposure. being also part of the third round of exposure studies organized by WHO, the used methodology followed the validated WHO?s protocol, as well. In each of the ten sampled areas from different brazilian regions, it was collected ten individual samples to form one pooled sample which was sent to the WHO?s reference laboratory in Germany. Human milk samples were mostly collected from human milk banks which are part of the National Human Milk Bank Network. Donors were selected considering the prior defined eligibility criteria. On worldwide level, the concentrations found in brazil were the lowest among the 24 participant countries. A monitoring program of these substances e others Persistent Organic Pollutants in human milk and environmental samples is proposed as prevention and control actions. Besides extending the knowledge about the occurrence of these compounds in Brazil, the study may subsidize international programs such as the Stockholm Convention and improve the management of chemical substances
