Utilizados em produtos industriais, dispositivos elétricos antigos e na agricultura brasileira até a década de 1980, esses poluentes ainda são encontrados no ambiente e na cadeia alimentar, contribuindo para a exposição humana. A preocupação com OCP e PCB não se limita apenas à sua presença persistente, mas também aos potenciais efeitos adversos, incluindo carcinogenicidade, toxicidade reprodutiva e neurotoxicidade.
To understand the risks associated with exposure to these contaminants, researchers from the Childhood and Environmental Pollutants Project (PIPA/UFRJ) investigated their concentration in maternal and umbilical cord blood, as well as in breast milk. The results were described in the article “Persistent Organic Pollutant Levels in Maternal and Cord Blood Plasma and Breast Milk: Results from the Rio Birth Cohort Pilot Study of Environmental Exposure and Childhood Development (PIPA Study)”, published in the journal “International Journal of Environmental Research and Public Health”.
Samples from 135 women and their newborns were analyzed, revealing the continued presence of these substances in the environment and the food chain. And although the concentrations found were not associated with statistically significant effects on maternal or neonatal health in the context of this study, the detection of these substances highlights the persistence and bioaccumulation capacity of POPs.
The study also addresses the importance of considering the sociodemographic and lifestyle characteristics of mothers, such as age, ethnicity, and pre-gestational body mass index, when assessing exposure levels and potential health risks. Statistical analysis found no significant associations between these factors and POP levels, but the authors suggest that future research should explore these relationships more thoroughly.
Finally, the article emphasizes the need for continuous monitoring of POP levels and actions to mitigate exposure to these pollutants, aiming to protect maternal and infant health.[/vc_column_text]
