motorists in the country can now contribute to cleaner air by spending a few extra bucks on a device which detects pollutants in the air and then releases oxygen. The gadget, controlled by a microprocessor, promises to save drivers from a hazards of carbon monoxide. Named
boston's Logan Airport in the us now has cleaner buses to transport passengers. These shuttle buses are designed to run on a blend consisting of 80 per cent diesel and 20 per cent
METAL foundries pollute the atmosphere by throwing up dust and giving off bad ~dour. While the former is easy to remedy, the latter poses a challenge. The vat-shaped biofilters designed to solve the problem are filled with moistened wood chips inoculated with bacteria. The air from the exhaust flows via …
JOHN Van der Sande, professor of material science at the MIT and his team are using a new technique to compile information on all types of soot. This knowledge will be used to detect the exact sources of pollution. The library of sootprints will be based on the molecular structure …
A new smog-eating automotive technology has been developed by Englehard Corporation of the US. The new automobile coating, designed to destroy ozone and carbon monoxide is now being evaluated by the California Air Resources Board (CARB). If the CARB finds the coating effective, "it could be one of the black …
HE green bug has finally bitten the Supreme Court. In a recent statement on March 30, Chief Justice A M Ahmadi declared that all official cars belonging to the court would soon run on compressed natural gas (CNG) instead of petrol or diesel. Natural gas is a gaseous hydrocarbon fuel …
Clean-air campaigners can't always pin down the source of a pollutant, by no means an easy task at best. Now, researchers at the Massachusetts Institute of Technology have devised a way to solve the problem. They are studying micro-structures in soot that should, in theory, trace each particle's history and …
THE BOOM over houses not only set windows rattling but made insomniacs out of deep snorers. That was a couple of decades ago, at least abroad. So the airlines tried to go in for whispering engines. After all this hullaballoo and court cases against erring airports, a definition of acceptable …
SCIENTISTS at the University of California at Berkeley in the US have developed a method that cuts to 1/10th the cost of cleaning up nitrogen oxides produced when fossil fuels are burned (Nature, Vol 369, No 6476). The new technology is also environmentally less harmful than the techniques currently used …
Plants have long been known as air purifiers, but now Paul Jackson, a microbiologist at Los Alamos National Laboratory, is using plant cells to purify liquids contaminated with heavy metals like barium and uranium, and with the residue of explosives like TNT. Jackson's "green filter" consists of a silica-based powder …
A RECENT UN accord on acid rain committed its 26 signatory nations to drastic cuts in sulphur dioxide emissions -- largely responsible for the phenomenon that wreaks havoc with humans, crops, lakes and forests. The cuts, scheduled for up to 2005 AD, range from 30 per cent for Canada to …
RECENT research findings have come as a breath of fresh air. A study based on data from 27 monitoring stations all over the world reveals that the carbon monoxide levels in the atmosphere have taken a nosedive and the atmosphere is getting cleaner for the first time in 3 decades …
