Study says plastic decomposes at sea – AP story

This story has personal relevency. I traveled to Belize two years ago, the first thing I found in the water when I waded in was a plastic bag from Whole Foods!  If you have more interest in this story, go to the PT Marine Science center and see their exhibets about plastics in the ocean. They surveyed many locations on our Jefferson County and other shorelines, and there was plastic pellets, the things that plastic breaks down into, in all samples…we are slowly drowning in plastic. Use reusable cloth bags whenever you can.

WASHINGTON — Environmentalists have long denounced plastic as a long-lasting pollutant that doesn’t break down. A new study indicates that, in the oceans, plastic does decompose, but says that’s not a good thing either.

Thousands of tons of plastic debris wind up in the oceans every year, some of it washing up on coasts, some being swirled by currents into the Great Pacific Garbage Patch between California and Hawaii, said to be larger than Texas.

“Plastics in daily use are generally assumed to be quite stable,” Katsuhiko Saido, a chemist at Nihon University, Chiba, Japan, said in a statement.

“We found that plastic in the ocean actually decomposes as it is exposed to the rain and sun and other environmental conditions, giving rise to yet another source of global contamination that will continue into the future,” said Saido, who presented his findings at the annual meeting of the American Chemical Society on Wednesday.

Saido reported that the decomposing plastics release potentially toxic chemicals such as bisphenol A and PS oligomer, which can disrupt the functioning of hormones in animals.
