Snails snack on poison metals
SOILS tainted with heavy metals from industrial pollution and sewage sludge may poison organisms that live in the soil far more readily than thought. The finding raises fears that unexpectedly high levels of toxins are getting into the food chain. Contaminated soils are given hazard ratings that are based on the key assumption that organisms can... view more... (2002-12-18)
Production of 'mint-scent'
In the industry, many tons of alcohol are used annually, as a starting point for the synthesis of many substances. Alcohol first has to be oxidised, after which aromas such as mint or cinnamon, or substances needed for the production of nylon are produced. Until now heavy metals such as chrome-oxide were used in the oxidation process. Ten Brink:... view more... (2000-03-03)
Heavy Metal Rocks Plant Cells too
Heavy metals can trigger widely varying stress reactions in plants. A team at the Campus Vienna Biocenter was now able to provide evidence for this in a research funded by the Austrian Science Fund (FWF). The results, now awaiting publication, are an important basis to comprehend how plants cope with an increase in heavy metal concentrations in... view more... (2004-09-22)
Nanoporous 'sponge' removes mercury from offshore produced waters
Contaminated water resulting from offshore oil and gas platform drilling contains mercury and other toxic heavy metals. view more (2006-03-30)
Heavy metals in the Peak District -- evidence from bugs in blanket bogs
Bacteria that consume heavy metals have been found in some of the most contaminated parts of the Peak District in the Southern Pennines and may be changing the pollutants into more toxic forms that could leak out into reservoirs. view more (2008-04-02)
MU researcher uses bacteria to make radioactive metals inert
The Lost Orphan Mine below the Grand Canyon hasn't produced uranium since the 1960s, but radioactive residue still contaminates the area. view more (2009-09-09)
Scientists Reveal The Dangers of Counterfeit Cigarettes
Scientists at the Universities of Glasgow and St Andrews have discovered high levels of a cancer-causing toxic metal in counterfeit cigarettes, widely available in the UK. The fakes are not only illegal but pose an extra health hazard to smokers buying them. The discovery was made when examining samples of the most popular cigarette brands sold... view more...

Adding high doses of sludge to neutralise soil acidity not advisable
A University of the Basque Country PhD thesis has analysed the application of waste sludge from EDAR (Estación Depuradora de Aguas Residuales - Waste Water Purification Plant) to acid soils which have limited capacity for neutralising the acidity. view more (2009-01-09)
Greenland Ice Core Reveals History of Pollution in the Arctic
New research, reported this week in the online early edition of the Proceedings of the National Academy of Sciences, finds that coal burning, primarily in North America and Europe, contaminated the Arctic and potentially affected human health and ecosystems in and around Earth's polar regions. view more (2008-08-20)
Study shows transfer of heavy metals from water to fish in Huelva estuary
A team of researchers from the University of Cadiz has confirmed that zinc, copper and lead are present at high levels in the water and sediments of the Huelva estuary, and have studied how some of these heavy metals are transferred to fish. view more (2009-06-16)
Sunflowers that love heavy metal
Sunflowers take up uranium twice or even three times better than their maize and soybean counterparts, making them a top 'clean crop' for removing toxic metals from the environment. Scientists at the Centre for Pesticides and Environmental Research, Yugoslavia, studied growth and uranium uptake in sunflower, soybean and maize crops. Sunflowers... view more... (2001-04-01)
Radioactive waste – no problem for metal-munching bacteria
A harmless soil bacterium, which can survive high-level exposures to gamma radiation, is being developed to clean up land contaminated with radioactive waste, experts heard today (Wednesday 12 September 2001) at the bi-annual meeting of the Society of General Microbiology at the University of East Anglia. US government researcher Dr. Michael Daly... view more... (2001-09-07)
Geologists use biotools to understand geosystems
Geologists are now becoming microbiologists in order to discover how biosystems affect geosystems. view more (2005-10-12)
Facile synthesis of nanoparticles with multiple functions advanced in Singapore
Nanostructured materials have garnered great interest worldwide due to their unique size-dependent properties for chemical, electronic, structural, medical and consumer applications. view more (2009-07-14)
Heavy metals accumulate more in some mushrooms than in others
A research team from the University of Castilla-La Mancha (UCLM) has analysed the presence of heavy metals in 12 species of mushroom collected from non-contaminated natural areas, and has found that the levels vary depending on the type of mushroom. view more (2009-11-02)
New sensor system improves detection of lead, heavy metals
The Department of Energy's Pacific Northwest National Laboratory has developed a new rapid, portable and inexpensive detection system that identifies personal exposures to toxic lead and other dangerous heavy metals. view more (2008-02-13)
Technologists develop robust soot filter for diesel engine
In a Technology Foundation STW project, Coen van Gulijk has developed a new concept for a robust soot filter for diesel engines. As well as filter stages, the filter has an open canal so as to exclude the danger of blockage and thus fire. The new soot filter consists of series of perforated ceramic foams. The surface of the ceramic is impregnated... view more... (2002-09-11)
Heavy Rainfall on the Increase
With at least one episode of serious flooding already this autumn, new research from the University of East Anglia (UEA) shows that one of the main contributors to flooding, three or more days of heavy rainfall in a row, is on the increase. view more (2001-11-19)
Exotic Materials Using Neptunium, Plutonium Provide Insight into Superconductivity
Physicists at Rutgers and Columbia universities have gained new insight into the origins of superconductivity - a property of metals where electrical resistance vanishes - by studying exotic chemical compounds that contain neptunium and plutonium. view more (2008-07-22)
Heavy metal link to mutations, low growth and fertility among crustaceans in Sydney Harbor tributary
Heavy metal pollutants are linked to genetic mutations, stunted growth and declining fertility among small crustaceans in the Parramatta River, the main tributary of Sydney Harbour, new research shows. view more (2008-08-25)
