Are plastic nanoparticles causing brain damage in fish?

Science
Sept. 25 (UPI) -- Fish may be suffering brain damage as a result of plastic pollution. New research shows plastic nanoparticles can end up inside the brains of fish."Our study is the first to show that nanosized plastic particles can accumulate in fish brains," Tommy Cedervall, a chemistry researcher at Lund University in Sweden, said in a news release.Cedervall and his colleagues tracked the path of tiny plastic particles through marine food chains. The nanoparticles can be consumed by plankton, and the plastic-stuffed plankton can be eaten by fish. If the plastic particles are small enough, they can sidestep the blood-brain barrier and accumulate inside a fish's brain.In tests, researchers found fish with plastic particles inside their brain tend to eat slower and spend less time explori...

A mission to the Pacific plastic patch

Science
A mariner who has spent years travelling "hundreds of thousands of nautical miles" to measure the impact of plastic waste in the ocean has estimated that a "raft" of plastic debris spanning more than 965,000 square miles (2.5m sq km) is concentrated in a region of the South Pacific. Capt Charles Moore has just returned from a sampling expedition around Easter Island and Robinson Crusoe Island. He was part of the team which discovered the first ocean "garbage patch" in the North Pacific gyre in 1997 and has now turned his attention to the South Pacific.Although plastic is known to occur in the Southern Hemisphere gyres, very few scientists have visited the region to collect samples.Oceanographer Dr Erik van Sebille, from Utrecht University, says the work of Capt Moore and his colleagues wi...
