In total, 491 organic compounds were detected and quantified in the pellets, with an additional 170 compounds tentatively annotated. These compounds span various classes, including pesticides, pharmaceuticals, industrial chemicals, plastic additives.
Present risk for all
There are few regulations on chemicals in plastics, and international trade in plastics waste complicate this issue.
In a correspondence published this month in the prestigious journal Science researchers from the University of Gothenburg, IPEN, Aarhus University, and the University of Exeter noted that: “The hazardous chemicals present risks to recycling workers and consumers, as well as to the wider society and environment. Before recycling can contribute to tackling the plastics pollution crisis, the plastics industry must limit hazardous chemicals.” More than 13 000 chemicals used in plastics with 25% classified as hazardous. Scientists state that “no plastic chemical [can be] classified as safe.”
“Need to phase out harmful chemicals”
Professor Bethanie Carney Almroth brings a clear message to next week’s meeting in Nairobi:
“Numerous studies show that hazardous chemicals can accumulate even in relatively close-loop plastic recycling systems. We need to rapidly phase-out plastic chemicals that can cause harm to human health and the environment.”
