  • 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 Awards Additional GLRI Funding to Federal and State Agencies to Expand Efforts to Target Harmful Algal Blooms in Lake Erie

    U.S Environmental Protection Agency today announced the award of Great Lakes Restoration Initiative funds totaling over $3.1 million to the National Oceanic and Atmospheric Administration, the U.S. Geological Survey, the USDA Natural Resources Conservation Service and the Michigan Department of Agriculture and Rural Development to target harmful algal blooms in Lake Erie. “This new Great ...

  • Air pollution modelling could help predict algal blooms

    Models that predict how nitrogen from the air is deposited in the sea could be useful in predicting algal blooms. Based on the knowledge that excess nitrogen increases algal growth rates, researchers simulated nitrogen deposition in the North Sea and suggested that, using predicted weather data, it might be possible to adapt this approach to predict algal blooms. Algae populations are kept under ...

  • EPA awards $300,000 small business grant for Berkeley, Calif. entrepreneur’s portable test for toxic algae blooms

    Today, the U.S. Environmental Protection Agency announced a $300,000 Small Business Innovation Research (SBIR) grant to HJ Science & Technology, Inc. in Berkeley, Calif. to build a portable instrument to analyze cyanotoxins in surface waters to help protect people from potentially harmful toxic algal blooms in lakes and rivers. “Supporting the growth of environmental small businesses in ...

  • Ohio River`s huge algae bloom a warning for water suppliers

    A toxic algae outbreak that snaked more than 600 miles down the Ohio River past four states is forcing water utilities to reassess the threat from harmful algal blooms that are popping up increasingly around the nation. Treatment plant operators and researchers along the river were surprised by the large bloom and said it should be a warning to cities that get their water supply from lakes, ...

  • Toxic algae blooming in warm water from California to Alaska

    A vast bloom of toxic algae off the West Coast is denser, more widespread and deeper than scientists feared even weeks ago, according to surveyors aboard a National Oceanic and Atmospheric Administration research vessel. This coastal ribbon of microscopic algae, up to 40 miles wide and 650 feet deep in places, is flourishing amid unusually warm Pacific Ocean temperatures. It now stretches from at ...

  • Cheap local clay kills harmful algae, study finds

    Local clay could help control the harmful algal blooms that destroy fish catch in the Philippines, according to researchers. Scientists at the University of the Philippines' Marine Science Institute found that the blooms — commonly known as red tide — can be mitigated by spraying 'ball clay', which ...

  • EPA Issues Health Advisories to Protect Americans from Algal Toxins in Drinking Water

    The U.S. Environmental Protection Agency (EPA) today issued health advisory values that states and utilities can use to protect Americans from elevated levels of algal toxins in drinking water. Algal blooms in rivers, lakes, and bays sometimes produce harmful toxins. Because utilities often use these water bodies as sources of drinking water, EPA has determined algal toxin levels in tap water ...

  • Phosphorus pollution research in great lakes

    NOAA has awarded New York-based Stony Brook University USD285,895 as part of an anticipated three-year, nearly USD500,000 project to determine how different kinds of phosphorous, a nutrient required by all plants for growth, trigger toxic blooms of blue-green algae in the Great Lakes. The project will focus on the algal species Microcystis, which frequently causes massive and unsightly blooms in ...

  • China tackles algae in Olympic venue

    More than 10,000 Chinese soldiers and civilians have been sent in to clear up a giant algal bloom threatening this summer's Olympic sailing events. The algae, first spotted in late May, has choked large stretches of coast around the Eastern city of Qingdao, according to local media. Workers are now heading out to sea every day to collect thousands of tonnes of algae around the city, which will ...

  • Algae Control Solution for Chilean Salmon Industry?

    Since February 2016, Salmon farms in Chile have been suffering from an intensive Harmful Algal Bloom (HAB) which is causing massive numbers of salmon deaths. Ultrasonic technology combined with algae detection could be the solution for an industry facing economic losses totaling millions. Currently the Dutch algae control company, LG Sonic, is discussing the implementation of ultrasonic ...

  • 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 ...
