Concerned by high levels of smog in the Washington area, the Sierra Club and three other groups have sued the environment protection agency (EPA) of the US to force Virginia, Maryland and the District to take better steps to clean up the smog. The environmental groups said in their lawsuit …
WITH the deadline to phase out ozone depleting substances (ODS) of the industrialised nations of the world already getting over, the countdown for developing nations has begun. As if to signal the urgency, an international conference on eco -refrigeration - fridges using chlorofluorocarbon (CFC) substitutes - was held in New …
ALL the diatribe and deliberations about protecting the ozone layer have not been just a lot of talk. Recently scientists reported that the concentration of ozone-depleting chemicals in the lower atmosphere began decreasing for the first time last year since their introduction in the early '60s. The discovery has revived …
RESEARCHERS have been trying to evolve a refrigerator that would cut down on power consumption and at the same time prevent the depletion of earth's ozone layer. Now, scientists from the Russian Institute of Light Alloys (VILS) in Moscow have successfully tested a new refrigerating unit that neither uses an …
OZONE levels have been depleting at the average annual rate of 4.3 per cent every decade in the Northern Hemisphere, and a slightly lower 4.1 per cent in the Southern Hemisphere, since 1979. These figures were disclosed by Rumen Bojkov of the World Meteorological Organization (wmo) in Geneva, Switzerland. The …
In a span of five years, Dutch sci4ntists R Hoekstra, C Elij and others at the Delft-based Institute of Applied Physics, have developed a spectrometer called the global ozone monitoring experiment (GOME). A spectrometer is a spectroscope equipped with a photoelectric photdAeter to measure radiant intensities at various wavelengths. GOME, …
WHILE the debate on global warming -continues, the detection of an astounding 45 per cent depletion of the mone layer, over an area stretching froth Greenland to western Siberia, gives atmospheric scientists MoTe woorries. The discovery was repwted by the World Meteorological Organization, a United Nations agetcy, in Geilmeva, Switzerland, …
EFFORTS to abolish the use of chlorofluorocarbons (CFCs) in developing countries, has received a jolt: evidence of a thriving black market for CFCs has been detected recently in the US. The chemical, which is wreaking havoc on the earth's fragile ozone layer, is used primarily in air-conditioning and refrigeration industries. …
THE race to save the depleting ozone layer may yet be won. Scientists belonging to the Yale University in New Haven, us, announced recently that they have discovered a new method by which chlorofluorocarbons (CFCs) which eat into the ozone layer can be broken down into harmless derivatives. A particular …
Shoppers in the US will now have a choke of refrigerators apprising them about the effect of the product on the environment thanks to a lawsuit. Four big refrigerator manufacturers agreed recently to relabel their products to inform the buyers that their appliances will harm the ozone layer, even though …
SURFACE ozone is produced as a result of chemical reactions in the atmosphere, driven by the action of ultra-violet (UV) radiation in the sunlight, involving both nitrogen oxides (NOX) and volatile organic compounds (VOCs). While both Nox and VOCs are emitted in large amounts by motor vehicles, other important sources …
THERE is apparently more to lightning than mere white flashes of light. Excited scientists from the National Aeronautics and Space Administration's Marshall Space Centre in Huntsville, Alaska and the University of Alaska in Fairbanks unknowingly stumbled upon bizarre bolts which materialise high above and strangely, instead of shooting downwards, they …
THE 10th anniversary of the Vienna Convention, which led to the 1987 Montreal Protocol, saw more than 100 governments meet at Vienna to continue the struggle to save the ozone layer. The two-week meet led to an agreement to add two new chemicals in addition to the existing ones to …
GOOD deal of attention has ently been given to scientific - ideas and information in emational relations literae - some of which looks scientific knowledge as a rce of foreign policy and international cooperation. e book in review makes a for understandiDg the portance of scientific knowledge as a political …
A HIGH-altitude Russian spy plane has been donated to western European scientists for studying ozone layer depletion over the Arctic region. Russia will provide the European Science Foundation in Strasbourg with (;eophysika, a specially transmuted version of the Mvasishchev Ni-55 aircraft, having an instrument bay capable of carrying more Than …
J C WILSON of the University of Denver has found that the first and only commercially run supersonic airliner - the Concorde - emits loads of sulphur particles in the atmosphere. He says that the discovery may compel engineers to alter the design of the engine and the fuels to …

The Republican Congressmen in the US continue to go hammer and tongs against all things environmental. This time it is the ozone layer. Led by representative John T Doolittle, partyman from California, they have introduced a hill to postpone until January 1, 2000, a ban on the production of chlorofluorocarbons …
EVEN as the un celebrated September 16 as the International Day for Preservation of the Ozone Layer, a report published by the World Metereological Organisation (wmo), considerably dampened the spirits of "save ozone" campaigners revealing that the hole in the stratospheric ozone layer -- which protects the earth from harmful …
