  • 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 ...

  • 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 ...

  • Toxics Persist in Washington Rivers, Lakes and Fish

    OLYMPIA, Washington - Toxic chemicals banned decades ago continue to linger in the environment and concentrate in the food chain, threatening people and the environment, according to three recent studies by the Washington state Department of Ecology. The new data on toxic contaminants in freshwater fish and sediments add evidence to the state's push to reduce and eliminate the use of toxic ...

  • Midwest`s postflood risk: toxic basements

    The oil, gasoline, fertilizers, and herbicides swept away by floodwaters in June pose an environmental challenge to the rain-soaked Midwest. But some of the most serious pollution problems may not lie outdoors. Instead, they could well lurk indoors in waterlogged basements and first floors of homes and businesses, where everything from cleaning agents to toxic metals accumulate in silt and mold. ...
