OZONE-LAYER - svensk översättning - bab.la engelskt

Gases such as CFC’s had damaged the ozone layer, creating a huge hole through which dangerous ultraviolet light could penetrate. Where the hole in the ozone layer developed, these dangerous rays penetrated and reached the earths surface. The industrial production of CFCs started in the 1920’s, causing an average reduction of the ozone layer of 3 per cent. Fortunately, chlorine has “natural enemies” as well, such as methane (CH4). Thanks to them, the natural ozone layer could recover over 50 years, as long as CFCs are no longer used on a global level.

ODS include chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), halons, methyl bromide, carbon tetrachloride, hydrobromofluorocarbons, chlorobromomethane, and methyl chloroform. ODS are generally very stable in the troposphere and only degrade under intense ultraviolet light in the stratosphere. The ozone hole is an area in the stratosphere above Antarctica where chlorine and bromine gases from human-produced chlorofluorocarbons (CFCs) and halons have destroyed ozone molecules.

This blanket of ozone, or O3, blocks most of the sun's Clean Air Act and U.S. Environmental Protection Agency (EPA) regulations further restricted the use of CFCs for non-consumer products.

Ozone - Engelska - Walesiska Översättning och exempel

A happy side-effect of the gradual ban of these products is that CFCs are broken down by the sun's ultraviolet rays, and chlorine atoms are released into the ozone layer, thus causing a chain resolution of the ozone layer. Harmful ultraviolet rays reaching the Earth increase. the stratosphere sunbeams the troposphere the ozone Layer CFCs (Case of CFC-11) 2019-05-22 · CFC-11 is one of a class of compounds called chlorofluorocarbons that destroy atmospheric ozone. They are also potent greenhouse gases that contribute to atmospheric warming. ADVERTISEMENTS: Read this essay to learn about the smuggling of CFC which is an ozone depleting substance. The gases, mainly chlorofluorocarbons, or CFCs, are used in air conditioning and refrigerators. Scientists say their continued use – particularly in populous developing counties—could undo efforts to replenish the ozone layer under the 1987 Montreal Protocol.

Ozone-depleting gases cause damage to stratospheric ozone or the "ozone layer". There is great uncertainty about the combined effects of different gases in the stratosphere, and all chlorinated and brominated compounds that are stable enough to reach the stratosphere can have an effect. The ozone layer, our Earth’s sunscreen, absorbs about 98 percent of this devastating UV light. The ozone layer is getting thinner. Chemicals called chlorofluorocarbons (CFCs) are a reason we have a thinning ozone layer. A chlorofluorocarbon (CFC) is a molecule that contains the element s carbon, chlorine, and fluorine. The processes through which CFCs harm the ozone layer are the same as the ones that eventually help remove CFCs from the atmosphere.
