A new technique for detecting Bisphenol A in the body challenges previous work. The rates noted by the researchers are much higher than those previously detected.
Do we really know how to detect the level of Bisphenol A in the body? A study published in The Lancet Diabetes and Endocrinology calls into question the results of previous analytical methods. The new technique developed by American researchers makes it possible to detect Bisphenol A in all its forms. The urine tests carried out show doses 44 times higher than those previously detected.
BPA is a chemical compound used in the manufacture of plastics. Several studies have identified human health risks associated with this substance. According to the Ministry of HealthBPA would have effects on reproduction, metabolism and could cause cardiovascular pathologies.
Worrying results
The tests carried out recently were carried out on 10 adults (5 women and 5 men) and on a second sample of 29 pregnant women. The results show a level of 51.99 nanograms of BPA per milliliter of human urine, previous tests indicated average levels of 1.2 ng/ml. This difference is explained by the very nature of BPA: when it is in the body, it is transformed into metabolites, chemical by-products that are difficult to detect. The new test is precisely capable of detecting BPA in all its forms.
Successive bans in France
“These results provide sufficient evidence that human exposure to BPA is much higher than previously assumed, conclude the researchers, (…) the current data underlines that the risks to human health have been dramatically underestimated.” In France, BPA was gradually banned in the manufacture of certain products, including baby bottles in 2011. Since 2012, the law has prohibited the manufacture, import, export and marketing of food packaging containing EPS. In 2013, the material was banned in objects, packaging and containers intended for young children. In 2015, the French authorities banned him from producing receipts.
Many studies
Regularly, new studies are carried out on BPA and reveal new aspects of its dangerousness. In 2018, scientists found that exposure to this substance had multi-generational consequences in research on mice. In 2017, another study shed light on the overexposure of plastics workers: in the United States, the analysis of the urine of 77 workers revealed rates 70 times higher than those of the general population.
