Monitoring seepage online
No one wants gasoline in the drinking water. That's why operators of landfill disposal sites and chemical plants monitor ground seepage beneath their facilities. Generally, as for suppliers of drinking water, samples are taken at legally required, predetermined intervals and sent to be analyzed for contaminants in the laboratory. This is... view more...

BIOMARKERS IN ADOLESCENTS COULD PROVIDE MEASUREMENT FOR ENVIRONMENTAL POLLUTION (p 1660)
Biological markers in adolescents could be a reliable measure of exposure to environmental pollutants, according to a study in this week's issue of THE LANCET which highlights how increased exposure among adolescents slows sexual development. Human exposure to chemicals is normally monitored by measurement of environmental pollutants externally.... view more... (2001-05-23)
New filter material can reduce the number of cigarette deaths
Using a new filter material of a network shaped polymer in filter cigarettes can significantly reduce the amount of tar and polycyclic aromatic hydrocarbons (PAHs) in the mainstream tobacco smoke. This is the conclusion of comparative experimental research carried out by Prof.Dr. Wim Rulkens and Dr. Hans Brons, Environmental Technologists at... view more... (2000-12-07)
Standardized house dust aids health researchers
Chemists at the National Institute of Standards and Technology (NIST) have created a standardized form of common house dust to support environmental scientists studying our everyday exposure to a catalog of potentially hazardous chemicals. view more (2007-02-02)
Rivers on Titan, one of Saturn's moons, resemble those on Earth
Recent evidence from the Huygens Probe of the Cassini Mission suggests that Titan, the largest moon orbiting Saturn, is a world where rivers of liquid methane sculpt channels in continents of ice. view more (2005-12-06)
New challenge for producers of refrigerators
The European Union has introduced a directive on waste electrical and electronic equipment (WEEE). The directive makes producers responsible for the recycling of the electrical and electronic equipment that they put on the market. The results from a study of refrigerators made by CIT Elektronik, Chalmers Industriteknik in Sweden, indicate that the... view more... (2003-11-26)
The longest carbon nanotubes you've ever seen
Using techniques that could revolutionize manufacturing for certain materials, researchers have grown carbon nanotubes that are the longest in the world. While still slightly less than 2 centimeters long, each nanotube is 900,000 times longer than its diameter. view more (2007-05-11)
A new way to look at lung cancer and tobacco carcinogens
Two types of cancer-causing agents in cigarettes-a nicotine-derived chemical and polycyclic aromatic hydrocarbons (PAHs) are the main culprits in lung cancer. Exposure to tobacco smoke - both mainstream and second-hand - is a leading cause of cancer death in the United States. view more (2008-05-29)
Drying wood with steam
Large quantities of wood chips are dried for the production of chip-board. Modifications to a widely implemented large-scale industrial process lead to enormous savings: 15 percent less heat energy is required and emissions are markedly reduced. view more (2002-02-01)
Gone With the Wind? Over A Hundred Scientists Take To The Skies To Track Global Air Pollution
This morning a team of forty scientists from seven UK universities will travel to the Azores to join hundreds more in the largest international atmospheric field campaign of its type ever attempted. The exciting mission will track and investigate a mass of polluted air as it leaves the United States and travels across the Atlantic to the UK and... view more... (2004-07-08)
University of Surrey Electronic Engineers' Revolutionary Discovery
A University of Surrey team led by Professor Ravi Silva has demonstrated a new method of growing carbon nanofibres at room temperature. Published in this week's Nature Materials, the technique they have used involves substituting the thermal energy requirements for growth with plasma decomposition of methane on the Ni catalyst. Professor Silva... view more... (2002-10-23)
Using video-game technology to find oil & gas
What do video games and seismic explorations have in common" Both require very demanding computer applications that call for the ability to process massive quantities of data rapidly. view more (2007-09-20)
MSU research strengthens link between smoking, pancreatic cancer
Researchers at Michigan State University have added yet another piece to the puzzle that links cigarette smoking with cancer of the pancreas, one of the deadliest forms of cancer. view more (2007-03-09)
The petroleum umbrella
Several companies are extracting black gold - petroleum - from the North Sea. But scientists are questioning this activity and asking if this activity has environmental consequences. By law, these companies are obliged to carry out annual analyses. view more (2005-04-04)
Mailman School of Public Health researchers report blood DNA can be early predictor of liver cancer
Researchers at Columbia University's Mailman School of Public Health have discovered a means for early detection of liver cancer. Using DNA isolated from serum samples as a baseline biomarker, the scientists examined changes in certain tumor suppressor genes that have been associated with the development of liver carcinomas. view more (2007-04-16)
Genetic predisposition increases childhood asthma risk
Children who carry variations in specific genes that metabolize vehicle emissions are more susceptible to developing asthma, particularly if they live near major roadways. view more (2007-08-21)
