Example of toxic chemicals found in electronic waste.
By Kingsley Adegboye
A NEW global survey has revealed that recycling of plastics containing toxic flame retardant chemicals found in electronic waste results in contamination of the world’s best-selling toys along with other children’s products. Ironically, the chemical contaminants can damage the nervous system and reduce intellectual capacity but are found in Rubik’s Cubes – a puzzle toy designed to exercise the mind.
Making this known in Lagos at the weekend, Mr. Leslie Adogame, Executive Director, Sustainable Research and Action for Environmental Development (SRADev Nigeria), said the study was performed by IPEN (a global civil society network), Arnika (an environmental organization in the Czech Republic) and SRADev Nigeria (a national NGO).
Adogame noted that the toxic chemicals, OctaBDE, DecaBDE, and HBCD, are used in the plastic casings of electronic products and if they are not removed, they are carried into new products when the plastic is recycled.
“The survey of products from 26 countries, including Nigeria, found that 90% of the samples contained OctaBDE or DecaBDE. Nearly half of them (43%) contained HBCD. In Nigeria, SRADev purchased 18 rubik’s cube-like toys and sent them for analysis to the Czech Republic. Fourteen samples were chosen for laboratory tests.
“The analysis found that all fourteen samples contained OctaBDE and DecaBDE at elevated concentrations. One of the samples from the Nigeria tested with the highest concentration of OctaBDE among 111 samples from 26 countries. These chemicals are persistent and known to harm the reproductive system and disrupt hormone systems, adversely impacting intelligence, attention, learning and memory.
“Toxic chemicals in electronic waste should not be present in children’s toys. This problem needs to be addressed globally and nationally. The study emerged just a few days before the global Conference of the Parties to the Stockholm Convention will decide whether to continue allowing the recycling of materials containing OctaBDE and possibly makes a new recycling exemption for DecaBDE.
The treaty’s experts committee have warned against the practice.
“Recycling materials that contain toxic chemicals contaminates new products, continues exposure, and undermines the credibility of recycling, “said Joe DiGangi, IPEN. “Governments should end this harmful loophole”, Adogame stated.
SRADev boss added that another critical decision of the Stockholm Convention Conference will be to establish hazardous waste limits, pointing out that protective hazardous waste limits would make wastes subject to the treaty’s obligations for destruction, and not permit their recycling.
According to him, “Surprisingly, some of the toxic chemical levels in children’s products in this study exceeded proposed hazardous waste limits. Overwhelming majority (13) of tested cubes purchased in Nigeria (14) exceeded the proposed waste limit of 50 ppm for PBDEs/OctaBDE. The cubes contained 395 ppm OctaBDE on average. One exemplar containing 1174 ppm OctaBDE was far beyond the protective level.
“We need protective hazardous waste limits. Weak standards mean toxic products and dirty recycling, which often takes place in low and middle income countries and spreads poisons from recycling sites into our homes and bodies”, Jitka Strakova, Arnika said.
Adogame further noted that “The application of strict hazardous limits is also critical for brominated flame retardants due to their presence in e-waste. In many countries, the Stockholm Convention standards will be the only global regulatory tool that can be used to prevent import and export of these contaminated wastes, in many cases from countries with stricter legislation to countries with weaker legislation or control”.
