Dolichospermum circinale (USGS) From the Mainstream Media / Dans les médias grand public North Carolina, USA: U.S. Fish and Wildlife Service agrees to pause algaecide project “Plans were in place to treat cyanobacteria, known as blue-green algae, using a product that the Environmental Protection Agency determined is toxic to birds in the 40,000-acre lake.” Key to managing nutrients is treating manure right in the pit “Technology created in Europe and backed by research confirms how inserting into the pit a nitrogen stabilizer called dicyandiamide (DCD) provides significant environmental and economic benefits.” Australia: New research provides guidance on integrating gene testing in cyanobacterial management “Despite the proven benefits of these molecular methods, they are not yet widely adopted in routine testing due to a lack of standardised guidelines for interpreting gene detection results within current risk assessment frameworks.” Québec, Canada : Carte in...

Lyngbya wollei From the Mainstream Media / Dans les médias grand public New York, USA: County cases may be link to ALS, algal blooms “Across northern New England, researchers have identified ALS hot spots–a large cluster in Vermont near Lake Champlain and a smattering of clusters among coastal communities in New Hampshire and Maine.” The Netherlands : Nitrogen deposition in vulnerable nature conservation areas is decreasing, but the legal standard cannot be met by 2035 “Although the reduction target has resulted in a steep decline in nitrogen deposition in vulnerable nature conservation areas, it is expected that only 40 per cent of nature reserves will be below the critical deposition value by 2035.” NOAA forecasts above-average summer 'dead zone' in Gulf of Mexico “It occurs every summer and is primarily a result of excess nutrient pollution from human activities in cities and farm areas throughout the Mississippi-Atchafalaya watershed.” Sweden: Key measur...

From the Mainstream Media / Dans les médias grand public Sweden : Nutrient load from horse farms should be included in eutrophication work “Research shows that nutrient leaching from horse farms can significantly increase phosphorus and nitrogen levels in nearby water bodies.” Vermont, USA : State to remove Lake Carmi aeration system after determining it made cyanobacteria blooms worse “Officials found it had “unintended consequences” of mixing phosphorus-rich bottom water with the rest of the lake.” Great Britain : Why polluted water held up 16,000 new homes "Stopping a pig farmer at a very sensitive site enabled us to make a huge saving in the amount of nutrients that end up in the river and we were able to mitigate for around 1,200 new homes." Florida, USA : Stuart, 5 nonprofits urge EPA to set toxic algae standard as FL ignores water quality laws “The city of Stuart, the nonprofit Friends of the Everglades and four other environmental advocacy organiza...

From the Mainstream Media / Dans les médias grand public Lakes Worldwide Need a Checkup “Some lake health symptoms, such as algal blooms, fish kills, and floating pollution, are readily visible via processes like satellite observation. But other concerns can be revealed only with diagnostic tests, which, like diagnostic tests for humans, can be expensive.” Great Britain : Tourist influx turns Windermere green, researchers say “Windermere is England's largest lake and one of the country's most popular natural attractions. High visitor numbers are turning one of Britain's most scenic lakes green, researchers say.” Lethal cyanobacteria are creeping into rivers—no one knows exactly why “Anatoxin-a is a fast-acting small molecule that causes sudden death as the toxin travels directly from the stomach into the bloodstream.” Podcast : AgEmerge: with Chris Jones, author of The Swine Republic, Struggles with Truth About Agriculture and Water Quality “Today he and...
