Microplastics 'pose toxic threat to marine biodiversity'
BBC News
Tiny particles of waste plastic that are ingested by shoreline "eco-engineer" worms may be negatively affecting biodiversity, a study says. So-called microplastics may be able to transfer toxic pollutants and chemicals into the guts of lugworms, reducing the animals' functions. An estimated 150 million tons vanishes from the global waste-stream each year.

Over the past decade, its sustainability efforts have garnered awards and international certifications. But its sale to Chinese meat processor Shuanghui International Holdings has raised new questions about the future of its sustainability commitments.

The Sydney Morning Herald
Mining poses a greater threat to the health of the Great Barrier Reef than agriculture, according to one marine scientist who has cast doubt on the Australian government's prediction that water quality will improve along the reef coast. Recently, federal Environment Minister Greg Hunt gave the green light to dredging and dumping associated with four coal terminals, and the building of a liquid natural gas refinery and pipeline on the Great Barrier Reef coast.

3 ways US-China conflict is helping on climate change
National Geographic
Beijing's air quality monitoring station was the first stop for Gina McCarthy, the top U.S. environmental official, in a weeklong trip to China for talks on how the world's top two greenhouse gas polluters can work together to tackle climate change. With no global treaty to reduce carbon emissions in sight, the trip is an effort by President Barack Obama's administration to demonstrate that efforts at bilateral cooperation hold promise.

US Northeast states ask EPA to crack down on Midwest pollution
Reuters
Eight Northeastern and mid-Atlantic governors petitioned the U.S. Environmental Protection Agency to require "upwind" states in the Midwest and South to curb ozone-forming pollution from their power plants, which they say travels downwind and poses health risks to their citizens. They want the EPA to force nine states to regulate the emissions that cross into their borders through prevailing winds and contribute to higher ozone levels to the north and east of the upwind states.

New tool assesses the impact of toxic agents in cells
EPFL via R&D Magazine
Nanopowders, nanocrystals, nanofibers, nanocomposites ... today we can find nanomaterials everywhere: in the products we consume and in our daily environments. In order to accurately determine their toxicity, researchers at the Federal Polytechnic Institute in Lausanne, Switzerland, have developed an analytical tool for measuring the oxidative stress that some of them provoke on cells.

Mass extinction the result of acid rain and ozone loss
Chemistry World
Widespread rain as acidic as lemon juice and the destruction of as much as 65 percent of the ozone layer may have played a major role in the largest mass extinction in the fossil record. This conclusion was reached by a U.S. team that used geological samples to develop a climate model that predicted extreme atmospheric effects that could have been behind the mass extinction at the end of the Permian.
