At least 3,000 more chemicals are present in plastics, from food packaging to children's toys to medical devices, a report has found. While the United Nations Environment Program (UNEP) and other institutions had previously identified 13,000 plastic chemicals, the report by a team of European scientists found more than 16,000 chemicals, a quarter of which are thought to be hazardous to human health. man and the environment.
Lead author Martin Wagner, an environmental toxicologist at the Norwegian University of Science and Technology, said hundreds and thousands of chemicals can be found in just one plastic product.
The report, funded by the Norwegian Research Council, comes as lawmakers grapple with drafting the world's first treaty to tackle growing plastic pollution, as some 400 million tonnes of plastic waste are produced each year.
Plastic can spread into the environment, including the water and food people consume, leading to health problems related to fertility and cardiovascular disease.
Industry representatives have said that any treaty should promote the recycling and reuse of plastics. But the scientists stressed the need for greater transparency about what chemicals are going into plastics, including recycled products. Only 6% of the chemicals found in plastics are internationally regulated.
All issues must be addressed in an international treaty, negotiations for which will continue next month in Ottawa, Canada, with the aim of finalizing it in December in South Korea.
