  • EPA updates national air toxics assessment

    The U.S. Environmental Protection Agency (EPA) today released the fourth update of a computer tool that helps federal, state, local governments and other stakeholders better understand the potential health risks from exposure to air toxics. The National Air Toxics Assessment (NATA) contains 2005 emissions data submitted primarily from the states for 178 pollutants. Models are used to make broad ...

  • Toxicity tests improve the assessment of harbour sediment quality

    Harbour sediments should be tested for their toxic effects on living organisms in addition to being subject to the chemical, physical and biological tests usually conducted to assess water quality, according to recent research from Portugal. This would provide a better environmental assessment of dredged material to help guide port authorities’ decisions on its disposal. Under the Water ...

  • EPA releases third national assessment of toxic air pollutants

    EPA has released the latest version of a state-of-the-science tool that estimates health risks from breathing air toxics in the United States. The National Air Toxics Assessment (NATA), based on 2002 air emissions data, helps federal, state, local and tribal governments identify areas and specific pollutants for further evaluation to better understand risks they may pose. Air toxics are of ...

  • 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 ecological toxicity in rivers

    Water quality in rivers is commonly classified according to its physical and chemical properties, but this may not fully describe its biological health. Polish researchers have tested a new method of water assessment, which looks at the toxicity to organisms of not just water, but also sediment and floodplain soil samples. This provides a more complete picture of a river's health and may help ...

  • Testing the toxicity of nanomaterials

    When the properties of materials are not fully understood, as with nanomaterials, how can they be adequately tested? A new study has found that two commonly-manufactured nanomaterials can damage human DNA. This highlights the need to evaluate the risks they might pose and design appropriate safety tests. Materials that damage DNA can cause human cells to mutate, which can eventually lead to ...

  • Government finally acts on toxic Bisphenol A

    The government of Canada is prepared to declare that Bisphenol A (BPA), a chemical commonly found in plastic baby bottles, reusable water bottles and the lining of some food cans should be classified as "toxic" under Canadian law. Although it is a bold move, the government is lagging behind business, where many have already removed BPA products from their shelves. The government has ...

  • 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 ...

  • $1 million given to Nye County, Nevada in U.S. EPA Brownfields grants to support site assessment and cleanup of toxics

    The U.S. Environmental Protection Agency today awarded approximately $1 million in hazardous substance and petroleum assessment cleanup grants to Nye County, Nevada as part of a $62.5 million in EPA Brownfields Assessment, Revolving Loan Fund, and Cleanup (ARC) grants awarded nationally to over 240 recipients. “These grants will go a long way to bring areas in southern Nevada back into ...

  • EPA Seeks Data Review to Assess Remaining Air Toxics Risks from 22 Industry Sectors

    Washington, D.C. - EPA is soliciting public comment on data the agency intends to use in analyzing risks from air toxics emitted from 22 industrial sectors. EPA will use the data to conduct risk analyses to determine if additional standards are needed to address remaining risks from the 22 sectors. In addition, EPA will perform a technology review for each sector. The agency seeks comment on ...

  • U.S. EPA announces $400,000 brownfields grant to Mt. Shasta to assess, clean up toxic former lumber mill

    Today, the U.S. Environmental Protection Agency (EPA) announced approximately $3.8 million in new pilot grants to nine recipients across the country for cleanup and redevelopment of contaminated properties. One of the grants will go to the City of Mt. Shasta, Calif., for a brownfields multi-purpose pilot grant. Petroleum grant funds will be used to assess and clean up the Roseburg Commerce Park ...

  • EPA Reorganizes Office of Pollution Prevention and Toxics (OPPT)

    The U.S. Environmental Protection Agency (EPA) Office of Pollution Prevention and Toxics (OPPT) recently noted that it successfully completed the Agency's reorganization process and that the effective date will be sometime after June 9, 2014. The reorganization, which Bergeson & Campbell, P.C. (B&C®) had discussed in its "Predictions" memo, available ...

  • New regulatory update on TCE toxicity values

    In a recent memorandum on interim recommended trichloroethylene (TCE) toxicity values, the U.S. EPA recognized that TCE is less toxic than previously assumed, resulting in more realistic screening levels and risk assessments. While final toxicity values for human health risk assessment have not been established for the Integrated Risk Information System, the EPA recommends the use of TCE toxicity ...
