Microplastics may transport hazardous plastic additives through marine environments
Plastic pollution is not only a marine litter issue; it is also closely linked to resource circulation and chemical management. Plastic products contain a wide range of additives, including antioxidants, plasticizers, ultraviolet stabilizers and flame retardants. Some of these chemicals are regulated or managed because of concerns about their effects on human health and ecosystems.
Microplastics in Japanese waters can carry hazardous chemicals used in plastic products, according to a study led by Go Suzuki. The researchers collected both tiny plastic particles and larger debris from various locations and analyzed the chemicals they contained. They found traces of additives like antioxidants, plasticizers, and flame retardants in both types of plastic.
Concentrations of certain chemicals, such as DEHP, were higher in smaller particles than in larger debris. This suggests that fragmentation can release chemicals from plastics into the marine environment, where they can be transported and potentially exposed organisms. The study highlights the need for better chemical management strategies to address marine plastic pollution, as simply controlling the production of certain plastics may not be enough to prevent the spread of harmful chemicals.
