| 单词 | Chlorofluorocarbon |
| 释义 | 含氯氟烴 Abbr – CFC. An aliphatic carbon compound (an organic compound containing open chains of carbon atoms) possessing both chlorine and fluorine atoms. CFC 11 (trichlorofludiromethane) and CFC 12 (dichlorodifluoromethane) have been commonly used as aerosol propellants. The Montreal Protocol on Substances that Deplete the Ozone Layer 1988 proposed the phasing out of CFCs. CFCs are known as ‘freons’ in the United States and ‘arctons’ in the United Kingdom. Chlorofluorocarbons are scheduled substances under the Ozone Layer Protection Ordinance (Cap 403), which was enacted to give effect to Hong Kong’s international obligations under the Vienna Convention for the Protection of the Ozone Layer 1985 and the Montreal Protocol on Substances that Deplete the Ozone Layer 1987. The manufacture of chlorofluorocarbons is prohibited: Ozone Layer Protection Ordinance (Cap 403) s 3. The importation and exportation of chlorofluorocarbons is controlled by way of a licensing scheme: s 4. See also Greenhouse effect; Ozone. 簡稱 – CFC 具有氯原子與氟原子的一種脂肪族碳化合物（一種含有碳原子鏈的有機化合物）。三氯氟甲烷及氯二氟甲烷普遍作為噴霧用的壓縮氣體。《1987年關於消耗臭氧層的物質的蒙特行爾議定書》建議分階段停止使用含氯氟烴。在美國，含氯氟烴被稱為氟氯烷，在英國則稱為冷煤。含氯氟烴是《保護臭氧層條例》（第403章）所指的受管制物質，該條例履行香港根據《1985年保護臭氧層維也納公約》及《1987年關於消耗臭氧層的物質的蒙特行爾議定書》而承擔的國際責任。生產含氯氟烴是受禁制：《保護臭氧層條例》（第403章）第3條。含氯氟烴的進口及出口是受特許計劃控制：第4條。另見 Greenhouse effect; Ozone。n. |
