A chemical used to deplete ozone layer. View Solution Ozone is an unstable, dark blue diamagnetic gas. It absorbs strongly the UV radiation, thus proteching the people on the earth from the harmful UV radiation from the sun. The use of chloroflurocarbon (CFC) in aeroslos and refrigrators...
Hemisphere polar region led to the 1987 Montreal Protocol on Substances that Deplete the Ozone Layer, the phasing out of CFCs worldwide and the expected gradual recovery of the stratospheric ozone layer - which is still not complete, owing to the long residence time of CFCs in Earth's ...
Then, they can react with ozone and deplete the ozone layer. Therefore, in order to save the ozone layer from being depleted, we should use other alternative chemicals such as butane and propane. 展开 关键词: Ozone Ultraviolet radiation CFC Butane Propane Article ...
cleaning solvents and foam blowing agents (such as fire extinguishers) used to contain CFCs and occasionally still do. The United Nations Environment Programme releases a list of chemical products that contain substances that deplete the ozone layer, as well as alternative products that do not harm ...
But they add to the depletion of the ozone layer. Using natural remedies and manmade manure for crops are ideal. This in turn improves the general health of the people. Don’t buy products with CFC’s : Although CFC’s are banned in most of the products, kindly make ...
Depletion of ozone in the atmosphere can have harmful effects on the environment and on human health. The Montreal Protocol on Substances that Deplete the Ozone Layer, an international treaty that protects the ozone layer by banning the use of substances believed to contribute to ozone depletion, ...
R-12: R-12 is the original chlorofluorocarbon (CFC) Freon used in car A/C systems until the mid-1990s. It was banned after the EPA discovered that it depletes the ozone layer. Vehicles manufactured pre-1995 often use R-12, but you can retrofit them with an R-134a system....
