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)
Sleaford groups consulted on water use futures
Representatives of civic groups and local council members have been invited to a meeting on Monday 1st November to discuss how they see land and water uses in the Slea catchment changing in the future. The meeting is being organised by Sleaford Development Group at the Solo Club, Seaford and will brief those attending about a study investigating... view more... (2004-10-29)
Researchers show how air pollution can cause heart disease
New York University School of Medicine researchers provide some of the most compelling evidence yet that long-term exposure to air pollution-even at levels within federal standards-causes heart disease. view more (2005-12-21)
NASA launches airborne study of arctic atmosphere, air pollution
This month, NASA begins the most extensive field campaign ever to investigate the chemistry of the Arctic's lower atmosphere. The mission is poised to help scientists identify how air pollution contributes to climate changes in the Arctic. view more (2008-04-02)
Tale of two deserts
There is a popular misconception that Middle Eastern deserts were once fertile because the climate was wetter in Roman times and that they lost their fertility because of mismanagement by man. In fact, research by University of Leicester archaeologists, with colleagues from the Universities of Bournemouth and Exeter, shows that the situation was... view more... (2002-10-28)
Diesel exhaust fumes affect people with asthma, finds study on London's Oxford Street
Diesel exhaust fumes on polluted streets have a measurable effect on people with asthma, according to the first study looking at exhausts and asthma in a real-life setting, published on 6 December in the New England Journal of Medicine. view more (2007-12-06)
Nitrogen - the silent species eliminator
Nitrogen pollution from agriculture and fossil fuels is known to be seriously damaging grasslands in the UK. A new European study is starting to show that the effect is Europe-wide, confirming that current policies to protect ecosystems may need a re-think. view more (2007-10-15)
The Sky Is Not Falling: Pollution in eastern China cuts light, useful rainfall
New research shows that air pollution in eastern China has reduced the amount of light rainfall over the past 50 years and decreased by 23 percent the number of days of light rain in the eastern half of the country. view more (2009-08-17)
Cockles and mussels reveal all
Cockles and mussels harvested on the shores of the Irish Sea may have provided a staple diet for Molly Malone and her fellow Dubliners, but for scientists at the University of Wales, Aberystwyth they are, along with longer living species such as the clam Arctica islandica*, a detailed record of pollution extending back over two centuries. The... view more... (2004-04-01)
UMCES-led research team quantifies nutrient pollution reductions from urban stream restoration
A team of researchers led by University of Maryland Center for Environmental Science researcher Dr. Sujay Kaushal has been among the first able to quantify the amount of excess nitrogen removed from an urban stream during environmental restoration projects. view more (2008-05-01)
Seagrass ecosystems at a 'global crisis'
An international team of scientists is calling for a targeted global conservation effort to preserve seagrasses and their ecological services for the world's coastal ecosystems, according to an article published in the December issue of Bioscience, the journal of the American Institute of Biological Sciences (AIBS). view more (2006-12-01)
Pine Is Ten Times As Sensitive As Maple
Coniferous trees are widespread in Russia, especially in Siberia, where taiga extends over tens of millions of hectares. Cedars and pines grow also in the environs of cities and in city parks and suffer from human-induced changes in environment. Of course, coniferous trees can withstand a low-level... view more...

The memory lingers longer
PCBs and dieldrin, for example, now banned for further industrial and agricultural use, are simply not breaking down in the environment as speedily as needed to meet environmental targets. Catchments of rivers in west Yorkshire with a long history of contamination by chemicals used in the wool-processing industry show persistent levels of these... view more... (1999-12-22)
Switchable solvents make chemical manufacturing more environmentally-friendly
Researchers from Queen's University and the Georgia Institute of Technology have discovered a new environmentally-friendly way to make chemicals for pharmaceutical and other industries, such as plastics, pesticides, dyes and fragrances. view more (2005-08-26)
Researchers discover way to transport environmental arsenic to plant leaves in new clean-up strategy
Environmental arsenic pollution is a serious and growing environmental problem, especially on the Indian subcontinent. Researchers at the University of Georgia had, several years ago, used genetic techniques to create "arsenic-eating" plants that could be planted on polluted sites. view more (2006-04-12)
Exhaust fumes boost asthma risk in genetically susceptible children
Exhaust fumes heighten the risk of asthma in children who are already genetically susceptible to respiratory disease, indicates research published ahead of print in the journal Thorax. view more (2007-08-21)
Diesel exhaust associated with higher heart attack, stroke risk in men
Increased roadway pollution produced by diesel fuel in vehicles is leading to a cascade of conditions that could result in heart attack or stroke. view more (2007-11-06)
'Immediate And Long-term Health Benefits' From Reduction In Sulphur Emissions (p 1646)
Reducing the sulphur content of pollutants can have a substantial impact in reducing death from respiratory and cardiovascular diseases, conclude authors of a study in this week's issue of THE LANCET which describes the effect of a public-health initiative in Hong Kong. A change in law to restrict sulphur emissions was introduced in Hong Kong in... view more... (2002-11-20)
