Bisphenol: plasticizers migrate directly into the blood

Bisphenol: plasticizers migrate directly into the blood

French researchers show how easily BPA gets into the body

Many toxic plastic products contain the toxic chemical bisphenol A (BPA) - this has been known for a long time. However, a current study shows how easily the carcinogenic substance gets into the body and what damage it can do there - because, as the French research team currently writes in “Environmental Health Perspectives”, “BPA can quickly and efficiently via those under the tongue heavily circulated oral mucous membranes. "

Hundreds of times the value when ingested through the mouth Bisphenol A gets directly from the mouth into the blood. As the researchers write, experiments with dogs had shown that the concentration of bisphenol A in the blood increased almost a hundredfold as soon as the chemical was absorbed through the highly perfused oral mucosa under the tongue and not through the digestive tract. The dogs were selected as experimental animals because the oral mucosa of the animals is very similar in nature to humans, with the researchers explicitly pointing out that "all animal procedures were carried out in accordance with the recognized standards of human animal husbandry".

BPA poses enormous health risks The so-called "plasticizer" is considered to be very dangerous because "it can damage nerves and even trigger cancer," among other things -Circulatory problems, lack of libido or obesity. Particularly problematic: "Bisphenol A is found in many everyday plastic products such as plastic bottles or the inner coating of cans, but also in the printing ink on receipts and tickets and often even in packaged foods".

BPA already banned in baby bottles Experts repeatedly warn of the health risks posed by the chemical, because according to various studies it is possible that even small amounts can get into the organism through the skin and cause damage there. As a first reaction to these findings, the "Standing Committee on the Food Chain and Animal Health" of the EU announced in November 2010 the ban on the production and sale of baby bottles made of polycarbonate, which contain BPA - which has also been in Germany since March 1, 2011 is in force. France, however, is on this issue already one step ahead: For here the chemical from the beginning of 2015 is prohibited in all food packaging, where addressed to infants under three years, since the beginning of 2013.
