Harmful chemicals in receipts and tickets
Greenpeace has verified significantly higher concentrations of bisphenol A (BPA) and bisphenol S (BPS) when examining purchase receipts on a large part of the receipts. The substances also used as plasticizers in plastic products are considered to be potentially hazardous to health and have therefore been prohibited in baby bottles, for example, since March of this year.
The chemicals on the receipts can get into the body through the skin and thus cause significant long-term health problems, warn the experts from Greenpeace. The environmental protection organization had examined the till receipts of eight companies and found significantly higher bisphenol A and bisphenol S values on seven receipts. According to Greenpeace, this is particularly critical since the bisphenol is much more concentrated on the thermal printing paper of the receipts than, for example, in plastic products and, moreover, it is much easier to dissolve on contact. The health risk associated with the bisphenol-laden till documents should therefore not be underestimated, warns Greenpeace.
Harmful chemical on almost all till receipts In the investigation carried out on behalf of the environmental organization "Greenpeace", an increased concentration of bisphenol was found on most receipts of the supermarket chains as well as on the printout of a ticket machine. The testers discovered on Edeka, Galeria's shopping lists Kaufhof and Deutsche Post Bisphenol A and on the receipts from Kaisers, Aldi Nord and Rewe the related bisphenol S. Deutsche Bahn ticket machines also contained bisphenol S. Only on the till vouchers of the Lidl supermarket chain did the experts find any residues of the harmful chemical The bisphenol, which is also used as a so-called plasticizer in plastic products, reacts with the thermal printing paper of the receipts to dye, which means that the invoice amounts and other information appear in black or dark letters However, the bisphenol sticks to receipts on which no reaction has taken place and thus leads to the significantly increased loads which have been proven. According to Greenpeace, bisphenol concentrations in the milligram range were detected on the till receipts, whereby according to the EU food authority Efsa, an intake of more than 0.05 milligrams of bisphenol A per kilogram of body weight can be classified as harmful to health. Children, in particular, are therefore particularly at risk because with a body weight of less than 20 kilograms, the consumption of just one milligram of bisphenol per day can bring about considerable health problems.
Health risk from bisphenol According to Greenpeace, the scientifically proven health risks of bisphenol include, for example, impaired development in small children, since the chemical can irreversibly damage the brain maturation of unborn babies and small children. Recent studies have also shown a link between bisphenol A and the risk of heart disease and breast and prostate cancer. In 2010, researchers also presented a study at the “Endocrine Society” science congress, which shows that bisphenol A significantly disrupts the hormonal balance and, among other things, favors diseases of the ovaries. In addition, last year US researchers from Harvard University came to the conclusion that bisphenol A can not only negatively affect the maturation of egg cells, but also the course of pregnancy. For example, women who were repeatedly affected by abortions had significantly higher BPA concentrations in their blood. Although all previous studies have primarily referred to bisphenol A, this does not mean that bisphenol S cannot have any adverse health effects. According to Greenpeace, BPS is very similar to bisphenol A and has so far only been researched much less well. BPS is often used as a substitute for BPA, as there is still little evidence of health risks to date. However, the Federal Environment Agency and the Federal Institute for Risk Assessment (BfR) are extremely critical of such a substitution of BPA by BPS, as recent studies suggest that BPS can even have a stronger estrogenic effect than BPA and thus threaten to have far more far-reaching effects on the hormone balance . In addition, BPS is broken down by the human body even worse than BPA, the experts warn. (fp)
