Eutrophication, Cyanobacteria, and Cyanotoxins Newsletters

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...

Microcystis bloom. From the Mainstream Media / Dans les médias grand public Finland : Finland's lakes warm up, raising algae concerns “The median temperature of lakes across the country is about 7 degrees warmer than the long-term average.” uPcycle: Towards a sustainable phosphorus future for freshwater and coastal ecosystems. “Bringing together global communities to deliver a sustainable phosphorus future to protect our freshwater and coastal ecosystems.” New Zealand : Call for better use of phosphorus “Manhire took part in Our Land and Water’s research and says trend data from farms and orchards show that most growers and farmers in New Zealand are responsible with their use of phosphorus.” Canada & USA : Lake Champlain: 2024 State of the Lake and Ecosystem Indicators Report “Produced every three years, the report reflects the most current scientific data and resource management approaches.” USA: Will a focus on stream health help boost the Chesape...

Oscillatoria princeps From the Mainstream Media / Dans les médias grand public Europe : Fostering European Lakes Restoration by Nutrient Removal, Recovery, and Reuse (FERRO) “We will develop a next-generation lake restoration approach by combining targeted restoration techniques with nutrient recovery and recycling to achieve multi-benefits: improved ecological status of lakes, support a circular economy, climate adaptation, support food production, promote biodiversity, and boost ecosystem services provision.” Florida, USA: EPA Petitioned to Protect Floridians, Wildlife From Toxic Algae Blooms “Five conservation organizations petitioned the Environmental Protection Agency today to set limits on the dangerous algae bloom toxins that now routinely threaten the health of Floridians and wildlife.” Ireland : Better Farming for Water Campaign Launched “Eight actions for change have been identified that farmers can take on their own farms which will lead to improvements in w...
