London breaches air pollution limit for all 2017
January 6, 2017 11:35 AM - Oliver Tickell, The Ecologist

Days into the 2017 pollution limits on the Brixton Road in Lambeth, South London, has already breached EU pollution limits for NO2 for the entire year. Meanwhile UK sales of diesel cars - one of the main causes of NO2 pollution - reached record levels in 2016, reflecting the government's failure to tackle the problem in spite of numerous court orders.

Traffic noise reduces birds' response to alarm calls
December 28, 2016 10:04 AM - Central Ornithology Publication Office via EurekAlert!

Pollution can take many forms--including noise. Excess noise in the environment from sources such as traffic can have negative effects on animals that rely on sound to communicate and get information about their surroundings. A new study from The Condor: Ornithological Applications shows that traffic noise makes birds less responsive to alarm calls that would otherwise alert them to dangers such as predators.

Chemicals of 'emerging concern' mapped in 3 Great Lakes

For the first time, researchers at the University of Illinois at Chicago have mapped the location of thousands of tons of polyhalogenated carbazoles in the sediment of the Great Lakes and estimated their amount.

The Deepwater Horizon Aftermath

Researchers analyze 125 compounds from oil spilled in the Gulf of Mexico to determine their longevity at different contamination levels.

The oil discharged into the Gulf of Mexico following the explosion and sinking of the Deepwater Horizon (DWH) rig in 2010 contaminated more than 1,000 square miles of seafloor. The complexity of the event has made it difficult for scientists to determine the long-term fate of oil in this ocean environment.

Sawdust Reinvented Into Super Sponge for Oil Spills
December 19, 2016 07:19 AM - Pacific Northwest National Laboratory

Lowly sawdust, the sawmill waste that’s sometimes tossed onto home garage floors to soak up oil spilled by amateur mechanics, could receive some new-found respect thanks to science. Researchers at the Department of Energy’s Pacific Northwest National Laboratory have chemically modified sawdust to make it exceptionally oil-attracting and buoyant, characteristics that are ideal for cleaning oil spills in the icy, turbulent waters of the Arctic. The nontoxic material absorbs up to five times its weight in oil and stays afloat for at least four months. 

Millions exposed to mercury in urban Pakistan

More than 40 per cent of Pakistanis living in urban areas are exposed to mercury contamination through dust particles and bioaccumulation, says a new study.  

The study, published last month (November) in Science of the Total Environment, amassed hair samples from 22 sites in five zones in Pakistan — Swat Valley & Gilgit-Baltistan regions, Kashmir Valley, Lower Himalaya Mountains and Indus Plains.

Researchers Solve Mystery Of Historic 1952 London Fog And Current Chinese Haze
December 14, 2016 03:01 PM - Texas A&M University

Few Americans may be aware of it, but in 1952 a killer fog that contained pollutants covered London for five days, causing breathing problems and killing thousands of residents.  The exact cause and nature of the fog has remained mostly unknown for decades, but an international team of scientists that includes several Texas A&M University-affiliated researchers believes that the mystery has been solved and that the same air chemistry also happens in China and other locales.
