  • Measures taken to help accelerate the phase out of ozone depleting chemicals

    EPA is taking the next step to eliminate harmful hydrochlorofluorocarbon (HCFC) emissions, which are ozone-depleting substances and potent greenhouse gases. “EPA is leading the way and working with the global community in helping to protect the environment for future generations with the phase out of HCFCs,” said Robert J. Meyers, principal deputy assistant administrator for EPA's Office of ...

  • Argentina and Spain combine to launch new ozone-measuring service

    The Argentine Meteorological Service, in collaboration with the Spanish Meteorological Agency and the government of the province of Tierra del Fuego, initiated a programme on 16 April 2008 to monitor atmospheric ozone from the global WMO Global Atmosphere Watch station at Ushuaia, Argentina (55°S and 68°W). At the same time, an ozonesonde was launched from Marambio station on the Antarctic ...

  • Dissolved ozone monitor for measurement of pure water in pharmaceutical industry

    Analytical Technology Inc. (ATi) announces that its Q45H/64 Dissolved Ozone Monitor enables continuous on-line monitoring and control of ozone systems in the pharmaceutical industry. The Q45H/64 Monitor from ATi helps pharmaceutical organizations to achieve compliance with regulatory frameworks in the UK and internationally. Ozone is commonly used in the pharmaceutical industry for the ...

  • New personal ozone monitors

    Amidst growing concern with the consequences of ground level ozone on health, and the continued failure of the UK to meet European air quality directives, Air Monitors, a specialist instrumentation company, has launched a new portable UV-based ozone monitor which significantly enhances the ability to measure the air that people breathe.  The handheld Personal Ozone Monitor (POM) allows ...

  • Antarctic Ozone Bulletin issued

    WMO has published the first issue in the 2015 series of the Antarctic Ozone Bulletin, with information on the state of the ozone layer in Antarctica and surrounding areas. Measurements with ground-based instruments and with balloon sondes from some stations in the Global Atmosphere Watch network show first signs of ozone depletion, according to the bulletin. Satellite observations show that ...

  • Ozone pollution is declining — but not everywhere

    Ground-level ozone is among the most harmful air pollutants in Europe today. Elevated ozone levels cause health problems, premature deaths, reduced agricultural crop yields, damage to plants in semi-natural ecosystems and corrosion of physical infrastructure and cultural heritage. Troublingly, efforts to combat European ozone levels are achieving only limited success. Although Europe has ...

  • Why is ground-level ozone not on the decline?

    Europe has significantly cut its emissions of gases that lead to ground-level ozone. Despite this, levels of ozone do not appear to be falling. A recent EEA report questions this and suggests that the effect of the emission cuts on ozone may be masked by variable weather conditions. In many countries of Europe, the time-series of ozone data are yet too short to draw conclusions about long-term ...

  • Ozone depleting substance found to be rising

    Measurements made at NIWA’s atmospheric research laboratory at Lauder are a key component in an article in the latest edition of one of the world’s most prestigious scientific journals, Nature. The international team of scientists, including NIWA researchers, Dan Smale and John Robinson, based their findings on measurements from a network of stations across the globe, ...

  • Avoiding harmful ozone pollution this summer

    High summer temperatures combined with air pollution can cause ground-level ozone to form, which has serious effects on health, especially for older people or children, or those with asthma and other breathing problems. The European Environment Agency (EEA) presents some useful information on protecting your health from ground-level ozone this summer. To date, the highest concentrations ...

  • Europe using less ozone-damaging chemicals

    Europe has made significant progress in phasing out chemicals which damage the ozone layer, according to a report from the European Environment Agency (EEA). The report considers production and use of more than 200 chemicals which damage the planet’s ozone layer, which are controlled by the Montreal Protocol and EU legislation. In the 1970s and 1980s, scientists established that ...

  • EPA Approves Redesignation of Charlotte Area to Attainment for Ozone

    The U.S. Environmental Protection Agency has announced that it is taking final action to approve the state of North Carolina’s request to redesignate the Charlotte area to attainment of the 1997 8-hour ozone standard. This action is based on air quality monitoring data for the three-year period of 2008, 2009, and 2010 that meets the standard. The area continues to attain this standard. On ...

  • Ozone pollution reduces tomato fruit yield and viability

    Ozone harms pollen viability of tomatoes, leading to reduced fruit weight, size and quality, a recent study has revealed. The researchers suggest the effect of ozone on pollen could be a useful way to rapidly test for pollution-induced stress on crop plants in risk assessments. Ground-level ozone damages plants as well as posing a risk to human health. It negatively affects crop yields and causes ...

  • 2007 Antarctic Ozone Hole Smaller But Not Recovering

    GENEVA, Switzerland, October 19, 2007 (ENS) - The Antarctic ozone hole this year is relatively small, but its size is not a sign of ozone recovery, the World Meteorological Organization, WMO, said Thursday. Instead, the smaller size of the ozone hole is related to the mild temperatures in the Antarctic stratosphere during the 2007 southern hemispheric winter. Since 1998, only the ozone ...

  • Commission welcomes agreement in Parliament on ozone layer

    The Commission welcomes the vote today by the European Parliament that confirms the first reading agreement reached between Parliament and Council on reinforcing ozone legislation. The agreement comes less than a year after the Commission's proposal was presented. In addition to updating current legislation on the protection of the ozone layer in light of scientific developments, the new ...

  • Should critical levels of plant ozone exposure be lower?

    ‘Critical levels’ of ozone exposure for plants, above which significant adverse effects may occur, are currently calculated by examining ozone’s impacts on only a small number of species. However, researchers have now compared this measure with a new approach which examines all species in a group, and defines the critical levels as the concentration at which 5% of species are ...

  • EPA Prioritizes Enforcement Measures

    Although the overall budget for the EPA in 2008 was cut, the amount of spending for enforcement operations increased $9.1 million over the 2007 amount to a total of $549 million. The Clean Air Act enforcement priorities include enforcement at coal-fire power plants, ethanol plants, petroleum refineries, wood products companies, and bakeries through a Bakery Partnership to work on ozone ...

  • The ozone hole of 2008 is larger than in 2007

    “After decades of chemical attack, it may take another 50 years or so for the ozone layer to recover fully. As the Montreal Protocol has taught us, when we degrade our environment too far, nursing it back to health tends to be a long journey, not a quick fix”, said Ban Ki-moon, Secretary-General of the United Nations, on the occasion of the International Day for the Preservation of Ozone Layer ...

  • EPA approves ozone plans for areas in extreme nonattainment

    The U.S. Environmental Protection Agency today approved the 8-hour ozone air quality plans for the two California areas with the worst air quality in the nation. These plans, known as State Implementation Plans, will enable San Joaquin Valley and South Coast to achieve the Clean Air Act’s 1997 8-hour ozone standard of 0.08 parts per million by 2024. There have been vast improvements in air ...

  • Hot summer weather exacerbating ozone pollution

    Unusually high temperatures this summer may be contributing to poor air quality in many European cities. Thresholds to protect health from ground-level ozone have been exceeded across Europe in recent weeks, according to preliminary data reported to the European Environment Agency (EEA). Ozone pollution has serious effects on health, especially for older people and children, or those with ...
