因此，非法进口氯氟化碳的黑市已经扩大。
Consequently, a black market in imported illicit CFC's has grown.
此外，氯氟化碳也用于灭火器中。
每年，全世界大约使用乃万公吨的氯氟化碳。
Each year, the world USES approximately 750,000 metric tons of CFC's.
然而，工业所需的氯氟化碳并不是容易被替代的。
However, the CFC's needed for industry are not easily replaced.
新的空调已经进入到空气，少量的氯氟化碳已被查封。
The new air conditioner is getting into the air, a small amount of CFCs has been sealed.
一批被广泛应用的称为氯氟化碳的气体造成了最大的化学威胁。
A group of widely used gases called chlorofluorocarbons (CFC's) posed the greatest chemical threat.
也许这样一来，就能够发现过量的氯氟化碳(如果外星人也使用头发定型剂的话)。
Or maybe finding excessive chlorofluorocarbons (if the aliens all use hairspray).
这样，即使立即停止所有氯氟化碳的生产，臭氧损耗的威胁也会持续一个多世纪。
So even if all CFC production stopped immediately, the threat of ozone depletion would continue for more than a century.
对科学家和化学工程师的挑战，是找到与氯氟化碳一样有效井没有其他有害效应的替代物。
The challenge for scientists and chemical engineers is to find substitutes that will be as effective as CFC's and that will not have some other group of harmful effects.
1987年9月，24个国家在加拿大的蒙特利尔签署了一个协议，以限制氯氟化碳的生产。
In September 1987, 24 nations signed an agreement in Montreal, Canada, to limit the production of CFC's.
电子设备制造商使用氯氟化碳清洗金属，并且一般都利用氯氟化碳作为制冷剂和制造泡沫绝缘材料。
Electronic equipment manufacturers use CFC's to clean metal, and CFC's are commonly used as refrigerants and to make foam insulation.
我们使用的氯氟化碳等臭氧消耗物质将保护我们免受有害的太阳紫外线辐射的臭氧层撕裂出一个空洞。
Our use of ozone-depleting substances such as chlorofluorocarbons (CFCs) had torn a hole in the ozone layer that protects us from the sun's harmful ultraviolet radiation.
根据该公约的《蒙特利尔议定书》，全世界团结起来减少了氯氟化碳和其他臭氧消耗物质的生产和消费。
Under its Montreal Protocol, the world united to slash the production and consumption of CFCs and other ozone-depleting substances.
氢氯氟化碳以替换破坏臭氧层物质的形式被引进进来，尽管氢氯氟化碳不会破坏臭氧层，但是它却是强有力的全球变暖催化剂，被当成“超级”温室气体。
Introduced as replacements for ozone depleting substances, HFCs do not damage the ozone layer but are potent global warming agents and considered 'super' greenhouse gases.
事实上，目前几乎每辆美国汽车和卡车都采用了氢氯氟化碳（hydrofluorocarbon）制冷剂。 与全球变暖潜力值为1400的HFC-1234yf款相比，HFC-134a 款采用的新型制冷剂全球变暖潜力值仅有4分之差。
The HFC (hydrofluorocarbon) refrigerant currently used in virtually every American model car and truck, HFC-134a, has a GWP of 1, 400 compared to the new refrigerant's (HFC-1234yf) GWP of just four.
而且在这些当中有些你或许认识，是二氯二氟化碳，它也是众所周知的氟利昂。
And, this one here, some of you might recognize, is dichlorodifluoromethane. It's also known as a CFC.
最后，炼油厂排放很多的气体，如二氧化硫(SO2)、二氧化氮(NO2)、二氧化碳、一氧化碳、甲烷、双环氧乙烷、氟化氢、氯、苯和其他气体。
Finally, refineries emit many gases like sulphur dioxide (SO2), nitrogen oxide (NO2), carbon dioxide, carbon monoxide, methane, dioxins, hydrogen fluoride, chlorine, benzene and others.
