  • How toxic are unregulated wastewater pollutants?

    Spanish and Dutch researchers have evaluated the environmental impact of chemical pollutants in wastewater in Spain. The results suggest that the most problematic pollutants may be derived from newer pharmaceutical and personal care products, such as everyday painkillers and soaps, not yet regulated. Water pollution is the main environmental concern for EU citizens, according to an EC ...

  • 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, ...

  • Introduction of On-line Toxicity monitor on WQTC 2006 Denver

    microLAN On-line Biomonitoring Systems for the first time introduced their newly developed TOXcontrol on-line biomonitoring system. This innovative toxicity analyser was based on the companies long term experience for on-line monitoring techniques and is using luminescent bacteria (Vibrio fischeri) for the detection of contaminants in water. This system can be used for Drinkingwater companies for ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Gas analyser radically enhances container testing and port security

    Instrumentation specialist Quantitech has announced that a new portable FTIR gas analyser has dramatically improved the testing of cargo containers at ports and airports. Dr Andrew Hobson explains: 'Existing portable instruments are limited in the range of parameters that they are able to measure, so it is often necessary to take grab samples for subsequent laboratory analysis. In contrast, the ...
