Plastic Breaks Down in Ocean, After All

August 20, 2009 Though ocean-borne plastic trash has a reputation as an indestructible, immortal environmental villain, scientists announced yesterday that some plastics actually decompose rapidly in the ocean. And, the researchers say, that's not a good thing. The team's new study is the first to show that degrading plastics are leaching potentially toxic chemicals such as bisphenol A into the seas, possibly threatening ocean animals, and us. Scientists had previously thought plastics broke down only at very high temperatures and over hundreds of years. The researchers behind a new study, however, found that plastic breaks down at cooler temperatures than expected, and within a year of the trash hitting the water. The Japan-based team collected samples in waters from the U.S., Europe, India, Japan, and elsewhere, lead researcher Katsuhiko Saido, a chemist with the College of Pharmacy at Nihon University in Japan, said via email.

Microbeads in Personal Care Products a Concern According to recent news reports, tiny bits of plastic from body washes and other products are polluting the great lakes. The problem is that these little balls of plastic are less than a millimeter across in size, so they’re too small be be caught by water treatment plants. “We’re plasticizing our water,” said Sherri Mason, principal investigator for the study.
