  • Ozone layer recovery may be delayed by greenhouse gas emissions

    The ozone layer in the stratosphere protects life on Earth from harmful radiation, but emissions from human activity have damaged this defence. A new study suggests that ozone recovery could be delayed, or even postponed indefinitely for some regions, by the impact of increasing amounts of greenhouse gases (GHGs) in the atmosphere. Although ozone at ground level is hazardous to health, ozone in ...

  • EPA money and support help make beach visits safe

    While it is still too cold to go to the beach in most parts of the country, EPA works year-round on ensuring beach visits are well-planned and safe for everyone. By providing states an additional $9.75 million in beach grants in 2008, EPA is helping states continue to monitor water quality at beaches and notify the public of beach warnings and closings when bacteria levels rise too high. “When ...

  • Several California Cities Rank Highest on the American Lung Association’s List of Most Ozone Polluted Cities

    Bonded activated carbon filters from UltraViolet Devices (UVDI) provide solutions for ozone removal in California and cities nationwide. The American Lung Association recently released their annual report, State of the Air 2010.  The report reveals ozone and particulate pollution levels found at monitoring sites across the country. The California cities of Los Angeles, Long Beach and ...

  • Space watch on air quality

    Sensitive sensors located in space are being drafted to help scientists monitor the state of the quality of the Earth’s air. With air pollution becoming one of the world's biggest dangers to society's health and an economic drain on some nations, current and up- to-date information on air pollution levels and their movement are vital to researchers tackling this problem. The ESA Earth Observation ...

  • Southern ozone hole slightly smaller this year

    Warm air at high altitudes this September and October helped shrink the man-made ozone hole near the South Pole ever so slightly, scientists say. The hole is an area in the atmosphere with low ozone concentrations. It is normally is at its biggest this time of year. NASA says on average it covered 8.1 million square miles this season. That's 6 percent smaller than the average since 1990. The ...

  • John Brown University Receives EPA Grant for Solar Water-Purification Project

    Today the U.S. Environmental Protection Agency (EPA) is awarding $14,520 to John Brown University in Siloam Springs, Arkansas, for a drinking water disinfection project in Guatemala under the People, Prosperity and the Planet (P3) program. Every year, the P3 program helps student teams pursue projects that deliver sustainable, alternative methods to address environmental challenges. The project ...

  • Hourly Ground-Level Ozone Forecasts Now Coast to Coast

    WASHINGTON, DC, October 3, 2007 (ENS) - Ground-level ozone forecasts, for years a key predictor of air quality in major U.S. cities, are now posted and mapped online on an hourly basis throughout the lower 48 United States. Ground-level ozone is a main ingredient of urban smog, that brown cloud hanging over the skylines of urban areas. 'Poor air quality is a silent ...

  • US settles with Costco to cut ozone-depleting and greenhouse gas refrigerant emissions nationwide

    Costco Wholesale Corporation, the nation’s second largest retailer, has agreed to cut its emissions of ozone-depleting and greenhouse gas chemicals from refrigeration equipment at more than half of its stores nationwide. In the settlement announced today by the U.S. Environmental Protection Agency (EPA) and Department of Justice (DOJ), Costco will pay $335,000 in penalties for federal Clean ...

  • Greenhouse Gas Concentrations Reach New Record

    The amount of greenhouse gases in the atmosphere reached a new record high in 2011, according to the World Meteorological Organization. Between 1990 and 2011 there was a 30% increase in radiative forcing – the warming effect on our climate – because of carbon dioxide (CO2) and other heat-trapping long-lived gases. Since the start of the industrial era in 1750, about 375 billion tonnes ...

  • Hot summer weather exacerbating ozone pollution
