  • Double first: ET launches new combined NOx and Ozone analyser

    ET is pleased to announce the new Teledyne API T204 NOx/O3 analyser measuring NO, NO2, NOx and O3 in a single, 19" rack mount instrument. The combined analyser is the same physical size as a standard NOx and weights just 18 kg. Combining the standard reference method monitoring technology of chemiluminescence and UV absorption together in a single package, the T204 truly delivers in terms of ...

  • 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 ...

  • Cost-effective way to analyse water

    New technology from GE will make it easier for the pharmaceutical industry to monitor and analyse water samples. The GE CheckPoint Pharma On-Line/Portable Total Organic Carbon (TOC) Sensor is typically mounted and used online for continuous monitoring. Measuring the levels of TOC in the water is an important step for pharmaceutical companies to control processes that are critical to their ...

  • 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 ...

  • New Ozone-Depleting Chemicals Found in the Atmosphere

    Four ozone-depleting gases, previously undetected in the atmosphere, have been found by new research. The work suggests that more than 74 000 tonnes of these human-made substances have been released since 1978, and that two are continuing to accumulate in the atmosphere. However, it is not yet known where they come from. The discovery of the hole in the ozone layer in 1985 led to a 130-nation ...

  • Environmental groups petition to overturn EPA ozone standard

    Health and environmental advocates filed a lawsuit Tuesday challenging the U.S. Environmental Protection Agency's refusal to adopt stronger standards for ground-level ozone proposed by the agency's own scientists. The American Lung Association, Natural Resources Defense Council, Environmental Defense Fund, the National Parks Conservation Association, and the Appalachian Mountain Club are taking ...

  • New trace chemical analyser for onsite analysis

    Quantitech (Milton Keynes) has announced the launch of the FROG-4000™, a rugged, portable instrument capable of analysing trace levels of individual volatile organic compounds (VOCs) in air, soil and water. “With this technology, operators will be able to conduct fast on-site analysis in a range of environmental, health and safety applications,” says Quantitech’s Dr Andrew ...

  • 2008 ozone hole larger than last year - ESA

    The 2008 ozone hole – a thinning in the ozone layer over Antarctica – is larger both in size and ozone loss than 2007 but is not as large as 2006. Ozone is a protective atmospheric layer found in about 25 kilometres altitude that acts as a sunlight filter shielding life on Earth from harmful ultraviolet rays, which can increase the risk of skin cancer and cataracts and harm marine life.  This ...

  • New Ozone Primary Transfer Standard SONIMIX 4001 with extended range.

    LNI Swissgas SA, based in Geneva has developed a new Ozone Primary transfer standard : the SONIMIX 4001. This generator is available in two models: 10 ppb to 1 ppm range with a flow rate of 3 L/min or with an extended range from 10 ppb to 10 ppm at 3 L/min plus 10 ppm to 35 ppm at 1 L/min. This ozone generator can be delivered with 2 different options: with an internal Zero Air generator ...

  • Asian air emissions increases ozone over western North America

    Increases in tropospheric ozone levels above western North America during springtime are due to eastward air flows across the Pacific Ocean, with the largest increases associated with air that comes from south and east Asia, according to a recent study. In the troposphere, the lowest layer of the atmosphere, high levels of ozone are considered to negatively affect human health and crop ...

  • Mediterranean ozone levels fall in rural areas, but rise in cities

    Air pollution legislation has led to reduced ozone pollution in rural areas in western Mediterranean countries; however, levels in urban and suburban areas are still increasing, new research concludes. This suggests that ground-level ozone, linked to human health issues as well as environmental damage, has the potential to become a more significant air quality issue than previously believed, the ...

  • Environnement S.A announces the AS32M: the unique analyser allowing quick and direct measurement of NO2

    The European Directive 2008/50/EC requires the measurement of nitrogen dioxide (NO2) at minima in all agglomerations of more than 100 000 inhabitants. Currently, some of these sites do not meet the limit values and quality objectives set, particularly on sites located in the vicinity of roads (traffic sites), directly impacted by vehicle emissions. The uncertainties related to measurement ...

  • New Ozone Attainment Standards to Generate Significant Public Health and Economic Benefits, Study Says

    Pittsburgh, PA (July 14, 2006) – Moving from current national ambient air quality standards for ozone to the more stringent California standards will produce significant public health and economic benefits, according to a statistical study published in the July issue of the Journal of the Air & Waste Management Association. The study was led by Bart D. Ostro, Ph.D., Chief of the Air Pollution ...

  • China exports air pollution to the North America’s West Coast

    Many of the measures taken by federal, state and local administrations in the United States to improve air quality on its West Coast are being thwarted by air pollution blowing across from China. This is the conclusion of research conducted by Wageningen University in association with the Royal Netherlands Meteorological Institute (KNMI) and the American space agency NASA, recently published in ...

  • Sharing environmental information across Europe to improve policies

    Public authorities across Europe collect a vast range of environmental data but different practices of classification and reporting make it difficult to access them and use them for cross-border analyses. The shared environmental information system (SEIS) aims to fulfill this gap by interconnecting existing databases, promoting the use of standards and making data accessible to all. The European ...

  • Global warming caused by CFCs, not carbon dioxide, study says

    Chlorofluorocarbons (CFCs) are to blame for global warming since the 1970s and not carbon dioxide, according to new research from the University of Waterloo published in the International Journal of Modern Physics B this week. CFCs are already known to deplete ozone, but in-depth statistical analysis now shows that CFCs are also the key driver in global climate change, rather than carbon ...
