• Next-gen solvents capture carbon with half the energy

    U.S. energy production could increase with the help of an improved carbon capture technology that use about half the energy of today's standard technologies. Emissions captured at fossil fuel power plants could in turn be used to harvest more crude by injecting it into underground oil fields.

  • Plastic pollution in the Antarctic worse than expected

    The continent is considered to be a pristine wilderness compared to other regions and was thought to be relatively free from plastic pollution. However new findings by scientists from University of Hull and British Antarctic Survey (BAS) have revealed that recorded levels of microplastics are five times higher than you would expect to find from local sources such as research stations and ships.

  • Researchers find way to reduce environmental impact of idling buses and delivery trucks

    Researchers at the University of Waterloo have developed a system for service vehicles that could reduce emissions and save companies and governments millions of dollars per year in fuel costs.

    In a study recently published in Energy, Waterloo engineers found a way to capture waste energy from service vehicles, such as buses or refrigerated food delivery trucks, as they are slowing down.

    They also figured out how to use that energy to replace the fossil fuels that are currently needed to operate secondary systems, such as air conditioning or refrigeration units, when the vehicles are stopped and idling.

  • NOAA, USGS and partners predict larger summer dead zone for the Chesapeake Bay

    Scientists expect this year’s summer Chesapeake Bay hypoxic or “dead zone” — an area of low to no oxygen that can kill fish and aquatic life — will be larger than average, approximately 1.89 cubic miles, or nearly the volume of 3.2 million Olympic-size swimming pools.

    Measurements for the Bay’s dead zone go back to 1950, and the 30-year mean maximum dead zone volume is 1.74 cubic miles.

  • Wildfires Pollute Much More Than Previously Thought

    Summer wildfires boost air pollution considerably more than previously believed.

    Naturally burning timber and brush launch what are called fine particles into the air at a rate three times as high as levels noted in emissions inventories at the U.S. Environmental Protection Agency, according to a new study. The microscopic specks that form aerosols are a hazard to human health, particularly to the lungs and heart.

  • China's Air Pollution Sharply Limits CO2 Uptake by Plants on Large Scale, Study Shows

    The exceptionally high levels of surface ozone, aerosol particles, and other air pollutants in China are damaging plants and interfering with their ability to absorb carbon dioxide, according to a new study.

    Researchers at the University of Exeter in the UK said that elevated levels of these pollutants in many parts of China are oxidizing plant cells and weakening the process of leaf photosynthesis and CO2 uptake. The impact of the ozone damage is so widespread that it actually has an effect on the regional carbon balance and impedes efforts to reduce planet-warming greenhouse gases, according to the study, published in the journal Atmospheric Chemistry and Physics.

  • Recent Clemson graduate uncovers a link between environmental toxicants and lipid metabolism

    While working for an environmental nonprofit organization in India, Namrata Sengupta investigated how poor waste management and sanitation practices can impact the environment and public health. Her work sparked an interest in environmental toxicology and led her to Clemson University in 2011 as a doctoral student in the field.

  • Why Microplastic Debris May Be the Next Big Threat to Our Seas

    Plastic, metal, rubber and paper are some of the materials that pollute the world's oceans, often in the form of soda cans, cigarette butts, plastic bags and bottles, and fishing gear.

    Environmental and marine science specialists call it "marine debris," which, simply put, means anything in the ocean that wasn't put there by nature.

    Recently, though, a new type of trash — microplastics — has become a focus for marine researchers, and they fear the impact of this type of debris may be especially dire.

  • Novel material removes pollutant PFOA to levels far below EPA's health advisory limit

    A highly toxic water pollutant, known as perfluorooctanoic acid (PFOA), last year caused a number of U.S. communities to close their drinking water supplies. Because of its historical use in Teflon production and other industrial processes as well as its environmental persistence, PFOA contamination is a pervasive problem worldwide.

  • Sydney Harbour emissions equivalent to 200 cars on the road

    The Sydney Harbour is renowned as a beautiful landmark straddling our thriving city  but a new study has shown it is also a source of significant carbon emissions, which requires careful management as the city is poised to double its population by the end of the century.

    That is the message of new research that has quantified CO2 emissions from the Harbour for the first time – found to be 1000 tonnes annually – equivalent to the pollution from about 200 cars.
