4 new gas that damage the ozone layer

4 new artificial gas, which was discovered by British scientists adversely affect the ozone layer. The danger that gaseous contaminants pose to the ozone layer is not gone: there are four new products that have arisen as a result of human activities and contribute to the reduction of the ozone layer. Two of the newly discovered gas to dangerously accumulate in the atmosphere. Depletion of the ozone layer has led to limit the production of chlorofluorocarbons (CFCs) since the mid 1980-ies. The origin of these new substances are still not known.





Scientists of the British Antarctic service (BASS) were the first discoverers of the huge hole in the ozone layer over Antarctica in 1985. The culprits were recognized by CFC gases, which were invented in the 20-ies of the last century. Now, researchers have found evidence that one hundred and four new gas can destroy the ozone in the atmosphere that these gases was not until the 1960's And suggested that they are the product of human activity. The research materials published in the journal Nature Geoscience.





The grim discovery. Scientists to research taking samples from the permafrost. The air extracted from the snow is an archive of what was happening in the atmosphere over the past 100 years. The experts also reviewed current samples taken at Cape Grim, Tasmania. According to his estimates, about 74,000 tons of these gases into the atmosphere. Still do not know where the new gases are extracted. Likely culprits are the manufacturers of insecticides and solvents.
