  • 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 confirms US coastal waters less toxic than 20 years ago

    US environmental laws enacted in the 1970s are reducing overall contaminant levels in coastal waters of the United States, finds a 20 year study released today by scientists with the National Oceanic and Atmospheric Administration, NOAA. But the study shows continuing elevated levels of toxic metals and oils near urban and industrial areas of the coast. Oil related compounds from motor vehicles ...

  • EPA plans new toxin guidelines for drinking water

    The U.S. Environmental Protection Agency plans to come out with new guidelines that will give cities and water treatment plants a blueprint for dealing with the type of algae-borne toxin that contaminated the drinking water in Ohio's fourth-largest city, a federal official said Wednesday. A new health advisory is on target to be finalized sometime next spring, said Peter Grevatt, director of the ...

  • Modified plant clears up deadly water toxin

    Plants may be a useful tool in clearing water of harmful toxins produced by blue-green algae, new research indicates. Some blue-green algae (cyanobacteria) — which grow in warm, nutrient-rich waters  — produce toxins that can severely damage the liver or nervous system. The effects of the toxins range from a mild illness to rapid death. They can remain in water supplies after the algae have been ...

  • Collection of soil and water samples underway in Camden County, MO

    The US Environmental Protection Agency is currently sampling soil and water from private wells at residences in Camden County, Mo. The samples are being screened for the presence of lead and other metals. There is no cost to the property owner or resident for the sampling. For most of its history, Missouri was the largest lead producer in the country. Historical records show that lead was mined ...

  • After Toledo water scare, states ask EPA for help

    Algae that turned Lake Erie green and produced toxins that fouled the tap water for 400,000 people in the Toledo area are becoming a big headache for those who keep drinking water safe even far beyond the Great Lakes. But with no federal standards on safe levels for drinking algae-tainted water and no guidelines for treating or testing it either, water quality engineers sometimes look for ...

  • Toxic algae blooming in warm water from California to Alaska

    A vast bloom of toxic algae off the West Coast is denser, more widespread and deeper than scientists feared even weeks ago, according to surveyors aboard a National Oceanic and Atmospheric Administration research vessel. This coastal ribbon of microscopic algae, up to 40 miles wide and 650 feet deep in places, is flourishing amid unusually warm Pacific Ocean temperatures. It now stretches from at ...

  • 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 ...

  • 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 ...
