Experts warn that about 90% of recipes that use fainting over time will contain carcinogenic chemicals.
Studies have shown that "bisphenolA", a chemical found in thermal paper, can cause hormone-related cancers. He has been associated with infertility, autism, obesity, type 2 diabetes and early puberty.
The public exposure to the chemical "BPA", which is often found in plastics, is already causing concern.
International researchers led by the University of Granada analyzed 112 thermal paper tickets and tickets in Brazil, Spain and France.
Professor Nicolas Olia, of the University of Granada, Spain, said that it was necessary to avoid receipts in bags or cars.
"We can recognize this type of paper because it instantly darkens if we place it near a heat source," he said.
According to the results published in Environmental Research, more than 90% of the revenues collected in Brazil and Spain were BPA, which is also half the revenue collected in France.
The French government has taken steps to limit the use of this chemical compound in thermal paper since 2014.
"For example, tickets should not come in contact with food, such as meat or fish, while they are being dumped in the kitchen," said Olia, adding that "we should not sing , play, write notes or even store them in bags or cars. " Hand ".
The researchers looked for alternatives to BPA, and BPS was designed after growing concerns about the impact of the plastic compound on human health.
However, scientists believe that "BPS" contributes to the disruption of hormones, causing dysfunction of the endocrine system. This is not a good option.
The researchers suggested refusing paper receipts until public health measures were taken, pointing out that Spain had promised to remove "BPA" from its receipts by 2020.
