Further evidence has emerged showing that a chemical used widely in plastic packaging and the lining of drinks cans may be harmful to health.
The latest study has shown that bisphenol A (BPA) can affect the way genes work in the brains of laboratory rats, although other scientists have questioned the relevance of the findings to humans.
Researchers found that feeding BPA to pregnant rats was associated with lasting alterations to the “epigenetic” structure of genes in the brain tissue of their offspring, causing possible changes to certain aspects of sex-specific behaviour, such as chasing, sniffing and aggression.
[…] The researchers concluded: “This study provides evidence that low-dose maternal BPA exposure induces long-lasting disruption to epigenetic pathways in the brain of offspring….Importantly, our findings indicate that these BPA-induced changes occur in a sex-specific, brain region-specific and dose-dependent manner.”
