  • EPA Statement: update on ongoing monitoring

    As a result of the incident with the Fukushima nuclear plant in Japan, several EPA air monitors have detected very low levels of radioactive material in the United States consistent with estimates from the damaged nuclear reactors. These detections were expected and the levels detected are far below levels of public-health concern. Elevated levels of radioactive material in rainwater have been ...

  • Analysis of produced water contaminants by ion chromatography

    Drilling for oil or gas holds many challenges. Keeping pipes free of scale deposits is one of them. This involves the monitoring of ionic components in produced water, a task that is best handled by ion chromatography (IC).Avoid clogging of your pipe systemProduced water is water trapped in underground reservoir rocks and is brought to surface along with the crude oil and gas. Besides dispersed ...

  • Straightforward determination of anhydrosugars in aerosols

    Metrohm presents a new method for the sensitive and robust routine determination of the «smoke markers» levoglucosan, mannosan and galactosan in aerosols. The method couples ion chromatography with a highly sensitive pulsed amperometric detector (IC-PAD) and provides a simple and less expensive alternative to GC/MS. As such, it facilitates research into the effects of biomass burning aerosols on ...

  • Harder rains set to fall as the world warms

    In not quite the words of the singer Bob Dylan, a hard rain is going to fall. Australian scientists predict that precipitation extremes with large variability will emerge in the Northern Hemisphere in the coming decades as part of a “wettening trend”. In other words, an even harder rain will fall − and then you’ll really know that the climate ...

  • Record-breaking heavy rainfall events increased under global warming

    Heavy rainfall events setting ever new records have been increasing strikingly in the past thirty years. While before 1980, multi-decadal fluctuations in extreme rainfall events are explained by natural variability, a team of scientists of the Potsdam Institute for Climate Impact Research detected a clear upward trend in the past few decades towards more unprecedented daily rainfall events. They ...
