  • EPA Announces 2014 Toxics Release Inventory Report

    In 2014, 84% of the 25 billion pounds of toxic chemical waste managed at the nation's industrial facilities was not released into the environment due to the use of preferred waste management practices like recycling, energy recovery and treatment, according to the U.S. Environmental Protection Agency's (EPA) annual Toxics Release Inventory (TRI) report. The remaining 16% was released to the air, ...

  • Fertilizers help toxic algae thrive in warming world

    Blue-green algae blooms that can turn toxic in freshwater lakes and can kill bathers, farm animals and domestic pets that drink the water are becoming more widespread across the world, according to new research. A combination of excess use of fertilizers containing phosphorus and nitrogen, untreated sewage releases, and warmer water caused by climate change is leading to an increasing threat of ...

  • Nanocoating on buildings releases potentially toxic particles to the air

    Weathering and abrasion are reported to cause titanium dioxide nanoparticles to escape from a self-cleaning coating for buildings. These particles may be toxic to humans and wildlife. The researchers have developed three indicators from the test results to help predict levels of nanoparticle release from these coatings. Photocatalytic coatings containing nano-sized particles of titanium dioxide ...

  • Mercury-resistant bacteria useful for studying toxic metal cycling

    Mercury-resistant bacteria could help scientists to understand more about mercury cycling in the environment. In a new study, researchers identified one particular strain of soil bacterium that could serve as a model for the conversion of the toxic metal into less toxic forms. They also discovered a new gene involved in the conversion process. Bacteria play an important role in the cycling of ...

  • Testing confirms toxic algae poisoned river and two reservoirs in US

    A California Superior Court judge has invited the North Coast Regional Water Quality Control Board to exercise its authority to regulate water quality to rid the Klamath River of toxic algae. The ruling by Judge Elaine Rushing comes in a lawsuit filed by Klamath Riverkeeper, the Karuk Tribe, and the Pacific Coast Federation of Fishermen's Associations, PCFFA, against the board. The groups filed ...

  • EPA releases 2013 Toxics Release Inventory National Analysis

    Similar to previous years, in 2013, most of the toxic chemical waste managed at industrial facilities in the U.S. was not released into the environment, according to the U.S. Environmental Protection Agency's (EPA) annual Toxics Release Inventory (TRI) report. The report, published today, shows that approximately 22 billion pounds— or 84 percent - of the 26 billion pounds of toxic chemical ...

  • New computer tool will help assess the toxic effects of lead on freshwater organisms

    A free-to-use computer model that helps regulators and industry ensure that rivers, lakes and streams are protected from the potential risks of lead has been developed by the International Lead Association. The biotic ligand model (BLM) can be regarded as a milestone in the ecological risk assessment of lead. It can predict how the toxic effects of metals on aquatic freshwater species ...

  • Great lakes still under siege from toxic pollution

    Canadian companies in the Great Lakes basin reported releasing more cancer-causing pollutants to the air than companies in the United States, according to a report released today by Great Lakes-area environmental groups from both sides of the border. Per facility, Canadian facilities emitted to the air, on average, almost three times more known cancer-causing pollutants. The comparison is based ...
