Earths Atmosphere Contains an Unexpectedly Large Amount of Ozone Depleting Compound

A newly published study from NASA shows that Earth’s atmosphere contains an unexpectedly large amount of Carbon tetrachloride (CCl4), leaving researchers to believe that there are either unidentified industrial leakages, large emissions from contaminated sites, or unknown CCl4 sources. NASA research shows Earth’s atmosphere contains an unexpectedly large amount of an ozone-depleting compound from an […]

Research Reveals Four New Gases in the Earths Atmosphere

New research from scientists at the University of East Anglia reveals four new man-made gases in the atmosphere that are contributing to the destruction of the ozone layer. New research published in the journal Nature Geoscience reveals that more than 74,000 tonnes of three new chlorofluorocarbons (CFCs) and one new hydrochlorofluorocarbon (HCFC) have been released […]

Researchers Develop a New Method for the Active Degradation of Organic Pollutants

By using swimming microengines, researchers from the Max Planck Institute have developed a new method for the active degradation of organic pollutants that is twelve times higher than when using immobile iron microtubes. Researchers from the Max Planck Institute for Intelligent Systems in Stuttgart have developed a new method for the active degradation of organic […]

Human Caused Air Pollution Results in Two Million Deaths Annually

A newly published study reveals that human-caused outdoor air pollution results in over two million deaths per year. In addition, while it has been suggested that a changing climate can exacerbate the effects of air pollution and increase death rates, the study shows that this has a minimal effect and only accounts for a small […]

Scientists Shed Light on Key Component of Pollution in China

A group of international researchers reveal in a new study that the amount of nitrogen deposited on land and water in China has increased 60 percent from the 1980s to the 2000s. It’s no secret that China is faced with some of the world’s worst pollution. Until now, however, information on the magnitude, scope and […]

Link Between Ozone Levels and Cardiac Arrest

Based on a massive data set unique to Houston, a newly published study from scientists at Rice University has found a direct correlation between out-of-hospital heart attacks and levels of air pollution and ozone. Researchers at Rice University in Houston have found a direct correlation between out-of-hospital cardiac arrests and levels of air pollution and […]

EU's-Carbon-Capture-and-Storage-Problem

Europe’s carbon-trading market and tougher emission targets make it appear somewhat more responsible than the rest of the world at climate-policy negotiations. But recently, the region has fallen behind North America in the effort demonstrate systems for capturing greenhouse-gas emissions from power plants and industry, even as its coal use increases. Europe has had trouble […]

The dredging of a highly contaminated canal long the shore of Lake Michigan, in Indiana, has begun, triggering concerns that the dredging could release harmful chemicals. The US Army Corps of Engineers is removing large volumes of contaminated sediment, equivalent of about 160 million truckloads, from the Indiana Harbor and Canal to create a deeper […]

Some of the world’s largest reserves of crude oil are held in the oil sands in Alberta, Canada, and production has been ongoing. A new study shows that contaminants from the development of the sands are stacking up in the environment. The scientists published their findings in the journal Proceedings of the National Academy of […]

Scientists report that there are alarmingly high methane emissions from oil and gas fields, undermining the environmental benefits of natural gas, which is transforming the current US energy system. The scientists, who hold joint appointments with the National Oceanic and Atmospheric Administration (NOAA) and the University of Colorado in Boulder, reported their findings at a […]

Scallops cough to expel feces and water from their central cavities. The friction between the mollusk’s two valves makes a sharp crack, followed by a drawn-out puffing sound as the valves close. Biologists think that these coughs could serve as an early warning system for worsening water quality. The scientists published their findings in the […]

European researchers are going to monitor thousands of people by giving them smartphones, which will record the chemicals to which they are exposed to every day. Two projects announced this week that they had won €17.3 million ($22.4 million) from the European Commission to study the exposome, the effects of environmental exposures on health. The […]
