  • Weather extremes provoked by trapping of giant waves in the atmosphere

    “An important part of the global air motion in the mid-latitudes of the Earth normally takes the form of waves wandering around the planet, oscillating between the tropical and the Arctic regions. So when they swing up, these waves suck warm air from the tropics to Europe, Russia, or the US, and when they swing down, they do the same thing with cold air ...

  • Concentrating emissions

    Researchers at MIT have shown the benefits of a new approach toward eliminating carbon-dioxide (CO2) emissions at coal-burning power plants. Their system, called pressurized oxy-fuel combustion, provides a way of separating all of the carbon-dioxide emissions produced by the burning of coal, in the form of a concentrated, pressurized liquid stream. This allows for carbon dioxide sequestration: ...

  • ASTM D3266 - 91(2011) standard test method for automated separation and collection of particulate and acidic gaseous fluoride in the atmosphere (Double paper tape sampler method)

    This test method provides a means of automatically separating and collecting atmospheric particulate and acidic gaseous fluoride samples. Since the samples are collected on dry tapes, the samples are in a form which allows elution of the fluoride content with a small volume of eluent. Consequently, the method allows analyses of air samples taken for a time period as short as several minutes. ...

  • Are emissions fueling Australian droughts?

    American scientists have just confirmed that parts of Australia are being slowly parched because of greenhouse gas emissions – which means that the long-term decline in rainfall over south and south-west Australia is a consequence of fossil fuel burning and depletion of the ozone layer by human activity. Such a finding is significant for two reasons. One remains contentious: it is one thing ...

  • Fossil fuel CO2 emissions up by 29 per cent since 2000, new testing confirms

    The strongest evidence yet that the rise in atmospheric CO2 emissions continues to outstrip the ability of the world’s natural ‘sinks’ to absorb carbon is published this week in the journal Nature Geoscience. An international team of researchers under the umbrella of the Global Carbon Project reports that over the last 50 years the average fraction of global CO2 emissions that remained in the ...

  • Reducing airline emissions – can it be done?

    The aviation industry is in for an interesting year as the European Union kicked off 2008 by agreeing on a system that forces airlines flying to and from Europe into a cap and trade system for greenhouse gas emissions. The EU system proposes to cap carbon dioxide emissions for european and foreign airplanes alike, while allowing airlines to ...

  • ASTM D4185 - 06(2011) standard practice for measurement of metals in workplace atmospheres by flame atomic absorption spectrophotometry

    The health of workers in many industries is at risk through exposure by inhalation to toxic metals. Industrial hygienists and other public health professionals need to determine the effectiveness of measures taken to control workers' exposures, and this is generally achieved by making workplace air measurements. Exposure to some metal-containing particles has been demonstrated to cause ...

  • Energy technologies are not enough to reduce carbon emissions

    Current energy technologies are not enough to reduce carbon emissions to a level needed to lower the risks associated with climate change, New York University physicist Martin Hoffert concludes in an essay in the latest issue of the journal Science. Many scientists have determined that in order to avoid the risks brought about by climate change, steps must be taken to prevent the mean global ...

  • ASTM E2817 - 11 standard test method for test fueling masonry heaters

    This test method is used for determining emission factors and emission rates for cordwood or other densified, binder free biomass fuel burning masonry heaters. The emission factor is useful for determining emission performance during product development. The emission factor is useful for the air quality regulatory community for determining compliance with emission performance limits. ...

  • Monitoring methane emissions from agriculture and dairy farming

    Methane (CH4) is the second most prevalent greenhouse gas emitted from human activities. In 2014, CH4 was responsible for around 11 percent of all US greenhouse gas emissions caused by human actions. Methane is emitted by a range of natural sources such as marshlands, leakage from natural gas systems and livestock farming [1]. Domestic ...

  • Study: Volkswagen’s excess emissions will lead to 1,200 premature deaths in Europe

    In September 2015, the German Volkswagen Group, the world’s largest car producer, admitted to having installed “defeat devices” in 11 million diesel cars sold worldwide between 2008 and 2015. The devices were designed to detect and adapt to laboratory tests, making the cars appear to comply with environmental standards when, in fact, they emitted pollutants called nitric oxides, ...

  • Individual power stations’ emissions can be identified from a distance

    Air pollutants and greenhouse gases (GHGs) from a coal-fired power station have been correctly identified 12 km away, researchers report in a new US study. Their monitoring method paves the way for a space-based satellite system which can check emissions reported by individual power stations against actual emissions. It is challenging to check the accuracy of emissions reported by nations under ...

  • New Coal Mine Methane Venting Technology Tested

    WASHINGTON, DC (ENS) - A demonstration project begun Friday at an abandoned West Virginia coal mine will showcase a technology that can convert the greenhouse gas methane into a source of clean energy. The thermal oxidation system destroys methane in ventilation air by heating the gas to over 1800 degrees Fahrenheit and converting it to carbon dioxide and water. The ...
