Order of the National Green Tribunal in the matter of In Re: News Item titled "Nayar river is vanishing - a yatra reveals conservation goes beyond science and policy" appearing in ‘The Down To Earth’ dated 03.06.2025. The original application was registered suo-motu based on the news item titled "Nayar …
following a widespread ban on the production of ozone-destroying chlorofluorocarbons ( cfc s), researchers in the us are now attempting to turn massive stockpiles of these substances into useful or at least benign materials. Chlorine atoms from cfc s are known to destroy stratospheric ozone, thereby causing exposure to harmful …
winter ice, which severely disrupts shipping in colder climes, may no longer pose a problem. A Canadian marine engineer, Per Andersen, claims that he has found a technique to control ice formation. His wave generator projector could prevent sea water from freezing, by producing artificial waves ( New Scientist , …
Researchers from the Southampton Oceanography Centre in the US have recently developed a measuring device which could enhance the efficiency of clean up operations following an oil spill. Traditionally, oil spills have been detected by radar. But once oil and water emulsify, the radar cannot be used to track the …
scientists from the University of Miami in Florida, us, have concluded that it is a toxin secreted from red tide which has caused a record number of deaths among manatees (sirenian mammals belonging to the genus Trichechus , found in the waters of the Atlantic and adjacent rivers) in Florida …
the slightest spark in a forest could turn into a major inferno, engulfing the entire vegetation in flames. This happens when the forest fire heats the air above it and fierce, high-speed winds cause the flames to spread. But surprisingly, scientists who study the behaviour of fires have rarely collaborated …
the best way to ascertain whether or not manufacturers are complying with pollution laws related to toxic hazardous metals, is to monitor what comes out of their smokestacks. Till now, scientists have been periodically monitoring emissions by studying samples from these factories in their laboratories. A study at source is …
researchers at the Long Ashton Agricultural Research Station near Bristol in southwest uk, are combining genetic engineering and largescale field experiments to find ways by which to reduce the use of pesticides, herbicides and fertilisers. Cutting down on the use of such chemicals will help protect the environment and also …
Ninety per cent of the world's most important food crops are threatened because human behaviour is pushing pollinators towards extinction. American entomologists Stephen Buchmann and Gary Nabhan argue in their recently published book, The forgotten Pollinators , that "The world is facing an impending global pollination crisis that may have …
Danish researchers have called for a national monitoring of lindane after traces of this chemical (banned in the country) were found in certain remote locations. An investigation by the Danish office for the Environment has established the fact that airborne lindane is being deposited in the southern and the western …
David Vaughan and Chris Doake, glaciologists with the Bristish Antarctic Survey have published a paper which states that atmospheric warming has caused the disintegration of five ice shelves in the Antarctic peninsula, over the last 60 years. The breaking down of the shelves has taken place in the warmest part …
nearly hundred and fifty years ago, William Grove, an amateur British scientist, discovered that he could produce electricity as a byproduct of the process which mixes hydrogen and oxygen to make water. Now, some British engineers say that his discovery will be the key to smog-free driving in the next …
Ionising radiation can be used to destroy pollutants like polychlorinated biphenyles (PCBs) and heavy metals from water. The radiation treatment is being developed at the US government's National Institute of Standards and Technology in Gaithersburg, Maryland, and the University of Maryland in College Park. In the case of a PCB …
the weathering of rocks is a natural phenomenon which leads to the enrichment of various metal ores. The process was found to be mediated by bacteria, as research conducted in northern Chile revealed. According to the findings of the study, bacteria could be mediators in copper sulphide enrichment during the …
The bacterium belonging to the Rhodococcus genus can not only neutralise benzene but may also be able to transform it into a source of useful chemicals. This was reported by microbiologists at the University of New South Wales in Australia. The bacterium neutralises benzene's effect by metabolising it. It destroys …
it may escape one's notice, but every time we breathe, we inadvertently inhale an invisible stream of gases, aerosols, particles, microbes, pollen and dust into our lungs. Although many take it for granted, it is an act that is not easy on millions of people all over the world. The …
research on finding safer substitutes for ods like cfcs, halons, and carbontetrachloride are underway. In fact certain replacements have already been made and are successfully being used. cfcs are regarded as being harmful because they damage the ozone layer which helps screen out damaging ultraviolet rays emitted by the sun …
