New Toxic Danger Posed by Ocean Plastic Trash
We know that plastic waste is overwhelming the ocean, sea life is dying from ingesting it and some even ends up in seafood. But scientists also now worry that plastic trash is coming with a side helping of toxic metals that latch onto plastic surfaces and enter the marine environment and food chain – and eventually, what people eat.

Metals, such as cadmium and lead, are often used in manufacturing plastic and over time can enter coastal waters. Once floating in the ocean or discarded on a beach and washed by the tides, plastics can also attract and concentrate a variety of metals already present in the environment that attach themselves, or “sorb,” to the surface. In both cases, the worry is that these metals – often toxic ones such as cadmium that are health concerns for both wildlife and humans – can contaminate waters or harm wildlife that ingest plastics, especially those that live in intertidal zones near sources of plastic pollution.
