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 ...

Cheap paper nano-sensor detects water toxins
Scientists have used nanotechnology to turn paper into a sensor that can detect toxins in drinking water. The China–US team dipped normal filter paper into a solution containing carbon nanotubes — which can conduct electricity — and antibodies to microcystin-LR, a common and dangerous toxin. They dried the paper and repeated the process until enough nanotubes were present to render it ...

Toledo warns residents not to drink the water
About 400,000 people in and around Ohio's fourth-largest city were warned Saturday not to drink its water after tests revealed the presence of a toxin possibly from algae on Lake Erie. Concerned residents of the Toledo area descended on city stores, buying carts full of bottled water, bags of ice and flavored water and emptying shelves within hours of the advisory, which was issued ...

Plants provide ‘green liver’ by removing water toxins
Blue-green algae, or ‘aquatic cyanobacteria’, can produce harmful toxins and present a serious health hazard when they bloom in large numbers. Researchers from Germany have now identified plant species that could be used to sustainably treat water by removing such cyanobacterial toxins. Cyanobacteria are common in water bodies with high nutrient load. Some cyanobacteria can produce ...

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 ...

PFAS Regulation Moves Forward at State, Federal Levels
States are increasing scrutiny of the widespread, long-lived chemicals, which often are found in tap water and the human bloodstream PFAS is the acronym for poly- and perfluoroalkyl substances, a class of more than 4,000 chemicals used in the manufacture of a wide range of consumer goods, including Teflon coating and food packaging. But because of their resistance to breaking down, they have ...
