  • How can we use phosphorus more efficiently and create opportunities for recycling?

    The Commission is launching a consultation on how to use phosphorus in a more sustainable way. Phosphorus is widely used in agriculture and is an essential component in fertiliser and animal feed, but it is a resource which has no substitute. Supplies are limited, prices have been volatile and much phosphorus is currently wasted, creating concerns about the cost and availability of future ...

  • How much phosphorus pollution makes lakes unsafe for recreation?

    A target level of 20 micrograms of phosphorus per litre of lake water could help keep many lakes safe for recreation by restricting the growth of harmful algal blooms, European research suggests. The scientists analysed the relationship between phosphorus levels in medium- and high-alkalinity lakes, the growth of cyanobacteria blooms and the concentrations of cyanobacteria that trigger World ...

  • 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 ...

  • Water quality improves after fertilizer ban - study

    In an effort to keep lakes and streams clean, municipalities around the country are banning or restricting the use of phosphorus-containing lawn fertilizers, which can kill fish and cause smelly algae blooms and other problems when the phosphorus washes out of the soil and into waterways. But do the ordinances really help reduce phosphorus pollution? That’s been an open question until now, says ...

  • HACH LANGE launches new UV-VIS Spectrophotometer

    In addition to the latest process monitoring equipment, the HACH LANGE stand at WWEM 2012 (No. 94/95/96) will also feature some of the company’s latest innovations in laboratory analysis including pocket colorimeters, portable water quality meters and sophisticated UV-VIS spectrophotometers such as the new DR 3900. The DR 3900 is fully automated and offers extremely high levels of accuracy, ...


  • Benefits of constructed wetland ecosystem services worth more than double the costs

    The economic benefits of the ecosystem services provided by constructed wetlands far outweigh the costs of maintaining them, new research has confirmed. Analysis of a wetland that treats the third largest lake in Florida, US, shows that it provides ecosystem services worth $1.79 (€1.64) million per year, against costs of less than half that figure. Eutrophication, an excess of nutrients ...

  • Nutrient levels on the decline in many Estonian rivers

    A new study has analysed the impact of industrial and agricultural changes on nutrients in Estonian rivers. The results indicated that there were significant reductions in nitrogen in one third of the sites, significant reductions in phosphorus in a quarter of sites and significant reductions in both nutrients in nearly a tenth of sites. High levels of nutrients, such as nitrogen and phosphorus, ...

  • Cutting nutrient pollution may curb harmful algal blooms

    Reducing nitrogen and phosphorus pollution may be an easier, more effective way to control harmful algal blooms in water than addressing warming temperatures, say researchers. Cyanobacteria, also known ...

  • Oxygenization of sea floor tested in coastal waters of the western Finland

    A joint Nordic three-year research project will show whether pumping of oxygen-rich surface water down to the bottom-near water layer can improve the state of coastal water that suffer from oxygen depletion. In anoxic conditions, nutrients stored in the bottom sediment, particularly phosphorus, are released into water. The Finnish research site is the Sandöfjärden water area in the western part ...

  • Understanding Chesapeake Bay nutrient trends

    Reducing the delivery of nutrients to the Chesapeake Bay (USA) is one of the most important components of restoration efforts to achieve a healthy Bay ecosystem. The USGS has developed a new method for tracking the progress toward reducing nitrogen and phosphorus delivery from the watershed to the Bay. According to Robert Hirsch, USGS Research Hydrologist who led the development of this ...

  • SEAL Analytical expands US manufacture

    The laboratory instrument manufacturer SEAL Analytical has transferred the production of its market leading automated discrete analyzers, the AQ1 and AQ2, to the company’s facility in Mequon, USA. The move follows the acquisition of a block digestion business from Aim Lab Automation Technologies Pty Ltd. SEAL’s President Stuart Smith said: “Digestion is an essential part of the ...

  • Four of nine ‘planetary boundaries’ exceeded

    Civilisation has crossed four of nine ‘planetary boundaries’, increasing the risk of irreversibly driving the Earth in to a less hospitable state, concludes new research. These are: extinction rate, deforestation, atmospheric CO2 and the flow of nitrogen and phosphorus. Planetary boundaries are scientifically based levels of human pressure on critical global processes that could ...

  • Everglades restoration continues despite water scarcity

    South Florida experienced a severe water shortage during Water Year 2007, more than a foot below historic averages for the region. From May 1, 2006 to April 31, 2007, low rainfall reduced flows across the entire region, according the annual report released Tuesday by Florida state agencies. The Florida Department of Environmental Protection and South Florida Water Management District report ...

  • SMHI and SYKE in Finland enter a unique collaboration on marine environmental monitoring

    SMHI and SYKE, the Finnish Environment Institute, have begun a close collaboration to monitor the marine environment of the Baltic and the North Sea. “It is unique for two countries to sign an agreement in this way, but we are leading a trend that the EU and the global organization ICES would like to see going forward. As a combined force we can improve the monitoring of the acute problems ...

  • What future for our food system? Let us know what you think

    In Europe we waste about 89 million tons of food every year. Environment Commissioner Janez Potočnik said: "This is morally and economically unacceptable and is all the more horrific when you consider the true scale of the resources required to produce those 89 million tons! We are also wasting all those resources. There's something wrong with the system." Food is essential to life. It forms ...

  • Phosphate monitor protects Cumbrian lake during restoration

    Novel phosphate monitoring technology from OTT Hydrometry is helping the South Cumbria Rivers Trust (SCRT) to improve water quality during a project to restore a lake in the north of England. Funded by United Utilities, the Elterwater Remediation Project has been created to improve water quality by increasing water flow through the lake and dramatically lowering residency time. Background ...

  • Successful trial for new remote Phosphate monitor

    Researchers at the UK’s Centre for Ecology & Hydrology (CEH) have conducted trials on the river Thames to evaluate a new remote phosphate monitoring technology (Cycle-P) as part of a high-frequency (hourly resolution) monitoring programme that is studying river nutrient concentrations and how they are affected by algal abundance. The monitoring system ran continuously over the summer of ...

  • New sewage sampler enables real-time control

    HACH LANGE has launched an innovative new wastewater sampling system, which will open up a new world of opportunity by enabling water companies to continuously monitor sewage at the plant inlet.
