Many translated example sentences containing "ozone depletion" The quantity of controlled substances of Group I (chlorofluorocarbons 11, 12, 113, 114 and  of R12 refrigerant gas, which is a chlorofluorocarbon (CFC), is controlled by Regulation (EC) No 1005/2009(1) on substances that deplete the ozone layer. Following bans on chlorofluorocarbons (CFCs) in the 1980s to slow depletion of the ozone layer, the new draft legislation targets use of several  en Damage of the ozone shield by chemicals released on Earth.

This is important because the ozone layer protects human skin and many living organisms from ultraviolet rays emitted from the sun. 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 … CFC gases were responsible for a massive hole in the ozone layer but they also had a powerful greenhouse effect.

The hydrochlorofluorocarbons (HCFCs) are less stable in the lower atmosphere, enabling them to break down before reaching the ozone layer. Nevertheless, a significant fraction of the HCFCs do break down in the stratosphere and they have contributed to more chlorine buildup there than originally predicted. Ozone gas (O 3) forms when oxygen molecules interact with ultraviolet rays from the sun.

Unlike the CFCs, however, most HCFCs are broken down in the lowest part of the atmosphere and pose a much smaller risk to the ozone layer. Nevertheless, HCFCs are very potent greenhouse gases , despite their very low atmospheric concentrations, measured in parts per trillion (million million). For example, the two gases carbon tetrafluoride (CF 4, produced mainly as a by-product of the manufacture of aluminum) and CFC-11 (CCl 3 F, used in a variety of human activities) are both much Ozone at High Risk From CFCs The ozone layer lies between about 9.3 and 18.6 miles (15 and 30 kilometers) above Earth's surface. This blanket of ozone, or O3, blocks most of the sun's China 'home foam' gas key to ozone mystery Ozone: The Earth's protective shield is repairing CFC-11 is also known as trichlorofluoromethane, and is one of a number of chloroflurocarbon (CFC) 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.

Ozone is a kind of oxygen in which each molecule has three atoms instead of two. The formula is O3 .
