UCSB researcher shows microplastic transfers chemicals, impacting health
Date:12/2/2013

as been found in animal studies to alter hormone regulation. Microplastic also increased the worms' susceptibility to oxidative stress by more than 30 percent.

These chemicals are known as priority pollutants, chemicals that governments around the world have agreed are the most persistently bioaccumulative and toxic. Previous work conducted by Browne and his colleagues showed that about 78 percent of the chemicals recognized by the U.S. Environmental Protection Agency are associated with microplastic pollution.

"We've known for a long time now that these types of chemicals transfer into humans from packaged goods," Browne said. "But for more than 40 years the bit that the scientists and policymakers didn't have was whether or not these particles of plastic can actually transfer chemicals into wildlife and damage the health of the organism and its ability to sustain biodiversity. That's what we really nailed with the study."
