关于雾霾的表达可是个技术活，英语中关于“雾”“霾”“烟”等的词汇可谓形形色色，一定要闹清楚了，下面举几个比较常见的词汇，具体情况如下，更多消息请关注应届毕业生网!
fog 雾
牛津词典给出的解释是这样的: thick cloud of tiny drops of water close to or just above land or sea;一般指靠近或悬浮于陆地或海洋上空的浓雾，能见度低。由此可见它的主要成分是水，常常指自然现象中的雾，对人体是无害的。
一般用thick, dense, light等形容词形容。
Dense fog is covering roads in the north and visibility is very poor.
浓雾笼罩了北部的公路, 能见度很低。
mist 薄雾
牛津词典给出的解释：cloud of minute drops of water vapour hanging just above the ground, less thick than fog but still difficult to see through;一般指薄雾、雾霭、雾气，这里已经很清楚地指出了，mist比fog轻、淡，但能见度仍然不是很高，所以，fog = thick mist。
一般用thick, dense, light等形容词形容。
early morning mists in autumn
秋日清晨的薄雾
haze 霾
The Free Dictionary给出的解释：Atmospheric moisture, dust, smoke, and vapor that diminishes visibility，a partially opaque covering;一般是由大气湿度、尘、烟、水汽等降低能见度的物体或不透明的悬浮颗粒引起的，而霾是指原因不明的大量烟、尘等微粒悬浮而形成的浑浊现象，核心物质是空气中悬浮的灰尘颗粒。因此，一定程度上来说haze包括霾，也可以用haze来表示雾霾。此外，haze还有薄雾、迷糊的意思。
一般用thick, dense, light等形容词形容。
a haze of cigarette smoke 香烟烟气
smog 烟雾
牛津词典给出的解释是mixture of fog and smoke ，即雾和烟的混合物。朗文词典给出的解释是dirty air that looks like a mixture of smoke and fog, caused by smoke from cars and factories in cities，明确指出了是由汽车尾气、工厂废气等烟气引起的空气污染，对人体是有害的;由此可见，用smog来形容雾霾是最贴切的。
可用dense、choking(令人窒息的)、noxious(有毒的)等形容词修饰。
而BBC、VOA、CNN等国外主流媒体对于雾霾的报道也是普遍倾向于用smog一词。

北京雾霾
For nearly 15 years the Chinese government has been talking about improving the air quality in Beijing, and by its own measures it seems to have done a pretty good job.
Since the city launched a campaign in 1998 to clean up the atmosphere, the number of “blue sky days” recorded by the government increased each year until 2011, when it achieved a record 286 days with supposedly clean air, compared with 100 in 1998.
But as anyone who has lived for long in Beijing can attest, “blue sky” is a somewhat redundant concept when applied to the celestial capital.
Over the weekend, air pollution readings in the city were the worst since records began about four years ago, with the concentration of fine particulates reaching a level 75 times greater than that considered healthy under the latest US standards.
A thick layer of toxic fog blanketing Beijing for days blotted out the sun and disrupted traffic as residents were warned to stay inside and avoid any strenuous activity to minimise their exposure to the hazardous fumes.
Despite years of official rhetoric and a couple of years when there was a noticeable improvement, the air seems to be getting worse and could even present the new administration of Xi Jinping with a credibility crisis. Chinese and international experts say one of the biggest problems the government faces is the willingness of officials at all levels to sacrifice environmental concerns for the overriding imperative of economic growth.
A lack of accountability, the weakness of agencies tasked with tackling the issue and the ease with which data collection and presentation is manipulated all compound the problem.
“China’s national leaders have ordered an improvement in air quality but thanks to misreporting and manipulation of data at the lower levels, they often aren’t aware of the severity of the problem,” says Steven Andrews, an environmental consultant who exposed official manipulation of air pollution data in Beijing in the run-up to the 2008 Olympic Games.
“For lower-level officials, they can often get the same results by manipulating the data as they do by enforcing emissions standards.”
Since enforcing these standards means confronting powerful state enterprises and power producers – many of which have emissions-treatment equipment installed but choose not to use it because of costs – many officials prefer to massage the numbers, Mr Andrews says.
Chinese scientists who have conducted independent studies on air quality say all sorts of tricks are used by the authorities in order to provide data that show improvements.
These range from blatantly changing the readings to putting city air monitoring stations in places where pollution levels are lowest, such as in parks.
Another problem is that China’s definition of unhealthy pollution levels seems designed to downplay the issue – the highest concentration of toxic particulates regarded as “excellent” in China is three times higher than the US considers healthy.
That many Beijing residents are even aware the “fog”?they?breathe is bad for them already marks a huge leap forward compared with just one year ago.
