  • 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 ...

  • EPA, NASA, NOAA and USGS Creating Early Warning System to Detect Harmful Algal Blooms

    The U.S. Environmental Protection Agency (EPA) announced today that it is developing an early warning indicator system using historical and current satellite data to detect algal blooms. EPA researchers will develop a mobile app to inform water quality managers of changes in water quality using satellite data on cyanobacteria algal blooms from three partnering agencies-- NASA, NOAA, and the U.S. ...

  • Link found between ‘algal blooms’ and liver disease

    Cyanobacteria — often referred to as blue-green algae — are found in water bodies around the world and can produce toxins with potential health risks. This US-wide study found a significant positive association between cyanobacterial bloom coverage and death by non-alcoholic liver disease. The researchers say their study suggests some evidence of a potential health risk and should be ...

  • EPA Planning to Issue Health Advisories On Harmful Algal Blooms by May 2015

    The Environmental Protection Agency is aiming to issue by May 2015 drinking water health advisories for cyanobacteria, the harmful forms of blue-green algae that contaminated water supplies in Toledo, Ohio, and resulted in a weekend-long ban in early August, an agency official said Sept. 29. The agency is working on health advisories for microcystin L-R and cylindrospermopsin, with plans to have ...

  • Geo-engineering to clean up decades of phosphorus pollution in lakes

    Phosphorus is the biggest cause of water quality degradation worldwide, causing ‘dead zones’, toxic algal blooms, a loss of biodiversity and increased health risks for the plants, animals and humans. This threatens the loss of economic and social benefits from freshwaters. Miquel Lurling of the Aquatic Ecology group was lead author of a special issue of Water Research on the control ...

  • Fertilizers help toxic algae thrive in warming world

    Blue-green algae blooms that can turn toxic in freshwater lakes and can kill bathers, farm animals and domestic pets that drink the water are becoming more widespread across the world, according to new research. A combination of excess use of fertilizers containing phosphorus and nitrogen, untreated sewage releases, and warmer water caused by climate change is leading to an increasing threat of ...

  • Fiscal Cliff Bill Makes Algae Eligible for Biofuel Producer Credit

    As part of the bi-partisan "Fiscal Cliff" legislation passed by the U.S. House of Representatives and the U.S. Senate on January 1, 2013, algae-derived fuels are, for the first time ever, a "qualified feedstock" under section 40 of the United States Code meaning that producers of algal fuel are eligible for a $1.01 per gallon tax credit. "Achieving tax parity with other biofuels has been a key ...
