A new study, “Toxic Soup: Dioxins in Plastic Toys”, released today, shows alarming levels of very toxic brominated dioxins in eight toys and one hair clip made of recycled plastic stemming from electronic waste. Dioxin content in toys from Czechia, Germany, France, Portugal, Argentina, India and Nigeria was comparable to the levels found in previous studies in waste incineration fly ash or other industrial waste.
This alarming information was released coinciding with the meeting of the EU Competent Authorities expert group for Regulation on Persistent Organic Pollutants (POPs), which will discuss rules for recycling and definitions of wastes containing persistent organic pollutants (POPs) such as Polybrominated diphenyl ethers (PBDEs) and dioxins. “To prevent the presence of highly toxic substances in toys, the EU and its member states have to withdraw their registration for recycling exemptions in the Stockholm Convention and introduce stricter limits for POPs in waste. We also need to get brominated dioxins listed among chemicals regulated under the Stockholm Convention,” explains Jindrich Petrlik, the main author of the study, Executive Director of Arnika - Toxics and Waste Programme, and Co-Chair of IPEN’s Dioxin, PCBs, and Waste Working Group.
Brominated dioxins are highly hazardous chemicals that are known to affect brain development, damage the immune system and unborn children, increase the risk of cancer and risk disruption of thyroid function. They occur as by-products in brominated flame retardants and as a result of incineration of brominated wastes and materials. “Bioassay analysis of dioxin-like activity has confirmed surprisingly high toxicity of recycled plastics,” said Peter Behnisch, one of the co-authors of the study and the Director of BioDetection Systems, a laboratory based in Amsterdam, Netherlands. “To our knowledge, this is the first publicly available study to show brominated dioxins in children’s products,” added Peter Behnisch.
The consumer products analysed were bought in 7 countries on 4 continents, and had been previously analysed for the content of another group of toxic chemicals, PBDEs. The significant contamination of children’s products by dioxins ranged from 56 – 3,800 pg WHO-TEQ/g. In at least one sample from each country, values in the order of hundreds of pg WHO-TEQ/g were found, as is the case with fly ash and bottom ash from waste incinerators. It did not matter whether the toy was obtained in Latin America, South Asia, Africa or the European Union.
The highest concentration of dioxins was found in a toy purchased in Germany. It was also the only sample that exceeded Germany’s legislative limit for brominated dioxins. "But it does not mean that other toys can be considered safe. The German limit does not include all the toxic brominated dioxin congeners. As brominated dioxins are in recycled products as impurities accompanying brominated flame retardants, it would be faster to prevent their further spread by tightening the limits for PBDEs in wastes to a level of 50 mg/kg, which would ensure elimination of dioxins from recycled plastics. This is the only way how to avoid toxic recycling,” said Manuel Fernandez, Chemicals Policy Officer in BUND/Friends of the Earth Germany.
