NASA Research: Toxic algae found in 2300 US lakes
NASA has just released a new dataset that shows 2300 lakes in the US are contaminated with cyanobacteria. In warm, stagnant, and nutrient-rich (nitrogen and phosphorus) water, cyanobacteria, also known as blue-green algae, can form HABs. Some HABs are toxic, harming aquatic ecosystems, people, animals, drinking water supplies, the economy, and recreational ...

Research focus on Australia’s rivers and wetlands
As a result of reduced water availability and unsustainable demands on our environment, Australia’s rivers, lakes, wetlands and floodplains have suffered severe degradation. There is growing recognition of the need to supply ‘environmental water’ to protect and conserve these important ecosystems. The Ecological Responses to Altered Flow Regimes Cluster, launched today by CSIRO ...

Environmental concentrations of antibiotics are potentially damaging to aquatic life
Combinations of antibiotics have been found in high enough concentrations to pose a serious threat to aquatic ecosystems, in a recent Spanish study. Antibiotics can have toxic effects on the bacteria and algae that form the basis of aquatic ecosystems. Antibiotics are in widespread use, not only for human medical conditions, but also for increasing growth rates in livestock, in the feed of ...

EPA issues latest information on toxic chemical releases - highlights for Alaska, Idaho, Oregon, and Washington (AK, ID, OR, WA)
Today EPA released the 2009 Toxics Release Inventory National Data Analysis. The 2009 data reports how TRI chemicals were managed, where they ended up, and how 2009 releases compare to 2008. Below are the highlights for EPA Region 10 (Alaska, Idaho, Oregon and Washington): Nationally TRI releases decreased by 12 percent between 2008 and 2009. TRI releases decreased in three of the four EPA ...

Climate change talks mustn`t forget fisheries
Saying that vulnerable fishing and coastal communities around the world will bear the brunt of climate change's impacts, a group of 16 international organizations today have urged climate negotiators to ensure that fisheries and aquaculture are not neglected in ongoing discussions regarding a successor to the Kyoto Protocol. In a policy brief issued today in advance of UNFCC talks in Bonn, ...

Silver nanoparticles could pose risk to aquatic ecosystems
Silver nanoparticles are toxic to common bacteria at concentrations found in many aquatic environments across the globe, new research has found. Bacteria often form a key part of ecosystems and these impacts may be felt by the entire system, the researchers warn. Silver nanoparticles are between one and a hundred nanometres (nm) in size and are now used for their antimicrobial action in a wide ...

Oklahoma, EPA study rivers, lakes and streams
The U.S. Environmental Protection Agency (EPA) and the Oklahoma Office of the Secretary of Energy and Environment (OSEE) are continuing to work on analyzing the condition of wetlands in Oklahoma, as part of a national initiative. The assessment will help build capacity to monitor and analyze wetland conditions while promoting collaboration across jurisdictional boundaries. OSEE will use a ...

Health of European streams revealed by leaf breakdown
A recent study, which assessed 100 streams across Europe, reveals that a key ecosystem process, leaf litter breakdown, is slowed when nutrient concentrations in the water are either very low or very high, has the highest potential at moderate nutrient concentrations and is inhibited in heavily polluted waters, implying that the relationship between nutrient levels and ecosystem processes, such ...

Decreasing nitrogen emissions will cause relatively fast reductions of impacts on ecosystems
The negative effects of acidic deposition in Europe and North America on natural ecosystems have been reduced significantly over the past decades, but the impacts of nitrogen on ecosystems are still persistent. This is evident from research results presented in a recently published book written by nearly 100 experts from 15 countries, entitled "Critical Loads and Dynamic Risk Assessments: ...

New guide to help reduce pesticide pollution in aquatic ecosystems
Pollution from agricultural pesticides can present a serious threat to aquatic ecosystems. Researchers have now developed a guide to identify the most appropriate measures to reduce pesticides entering waterways. It focuses on reducing pesticide entry via spray drift or runoff. In Europe, the Sustainable Use of Pesticides Directive1 has established a framework which is designed to reduce the ...

Tidal Marshes protect aquatic ecosystems and store carbon
A team of scientists measured nitrogen and phosphorus retention and carbon sequestration by tidal marsh soils along the Georgia coast to document the role of these wetlands in storing carbon and removing nutrients at the landscape scale. The results suggest that tidal marches protect aquatic ecosystems from eutrophication, caused by the accumulation of nutrients that disrupts ecosystems and ...

EPA to open public comment on proposed standards to protect aquatic ecosystems
Today, as required by the Clean Water Act and pursuant to a settlement agreement, the U.S. Environmental Protection Agency (EPA) is proposing for public comment standards to protect billions of fish and other aquatic organisms drawn each year into cooling water systems at large power plants and factories. The proposal, based on Section 316(b) of the Clean Water Act, would establish a common sense ...
