Rambo Tribble writes "An article in Current Biology (abstract) details the finding that minute particles of plastic waste are affecting marine worms, potentially having grave impacts on marine biodiversity (PDF) and leading to the accumulation of toxins in marine animals. 'The team found that the tiny bits of plastic, which measure 1mm or smaller, transferred pollutants and additive chemicals — such as flame-retardants — into the guts of lugworms (Arenicola marina). This process results in the chemical reaching the creatures' tissue, causing a range of biological effects such as thermal stress and the inability to consume as much sediment.' Unfortunately, policymakers have routinely treated such wastes as benign. The BBC provides more approachable coverage of the findings."
