  • Measuring the impacts of the Nitrates Directive on nitrogen emissions

    The EU’s Nitrates Directive has led to significant decreases in nitrogen pollution in Europe, a new study suggests. Modelled scenarios with and without implementation of the Directive showed that it had resulted in a 16% reduction of nitrate leaching by 2008. These improvements could be further increased as implementation becomes stricter, the researchers conclude. More nitrogen is applied ...

  • Iowa copes with nitrate surge in drinking water

    For much of last year, Iowa's most pressing agricultural problem was a drought that baked farm fields and parched crops, turning them brown and crumbly. Then the skies finally opened up, providing one of the soggiest springs on record. But the rain has created a new, unexpected problem: The deluge is washing fertilizer off the farms and into rivers that provide drinking water to much of the ...

  • ASTM C799 - 12 Standard Test Methods for Chemical, Mass Spectrometric, Spectrochemical, Nuclear, and Radiochemical Analysis of Nuclear-Grade Uranyl Nitrate Solutions

    Uranyl nitrate solution is used as a feed material for conversion to the hexafluoride as well as for direct conversion to the oxide. In order to be suitable for this purpose, the material must meet certain criteria for uranium content, isotopic composition, acidity, radioactivity, and impurity content. These methods are designed to show whether a given material meets the specifications for these ...

  • St. Lawrence County Cheese Manufacturer to Upgrade its Operations in Agreement with the EPA

    The U.S. Environmental Protection Agency announced a legal settlement with Losurdo Foods Inc. of Heuvelton, New York that will reduce the amount of pollutants the company discharges to the municipal water treatment plant. Losurdo has agreed to upgrade its cheese manufacturing equipment, resulting in a 16% reduction in the amount of nitrate compounds and a 50% reduction in the amount of wastewater ...

  • Water pollution is decreasing but a lot remains to be done

    Water pollution caused by nitrates has decreased in Europe over the past two decades, but agricultural pressures are still putting water resources under strain. The latest Report on the implementation of the Nitrates Directive reveals that nitrates concentrations are slightly decreasing in both surface and groundwater and sustainable ...

  • Risks of biodiversity loss posed by nitrogen and phosphorus pollution in European freshwaters

    The risk of eutrophication as a result of nitrogen and phosphorus pollution in Europe’s freshwaters fell by 22% in lakes and by 38% in rivers between 1985 and 2011, new research has shown. The researchers analysed data across 88 European river basins using a new statistical approach which could be used to help identify factors which increase eutrophication risks. Nitrogen and phosphorus can ...

  • Fertilisers linked to contaminated drinking water in Evros, Greece

    In a new study, samples of drinking water from the north-east of Greece have been found to exceed European limits for nitrates, sulphates and phosphates - chemicals that are linked to health problems such as reproductive disorders and cancer. The research has produced a map of the Evros area showing the location of 64 water sampling sites and found that pollution levels are highest in areas with ...
