环保部称将大力防治机动车尾气污染 译者：yinchaoliang  Post By：2013/1/15 12:51:22
环保部昨天表示，我国将全面实施机动车氮氧化物总量控制，切实加强机动车生产、使用、淘汰等全过程环境监管，加大力度防治机动车尾气污染。
我国已连续三年成为世界机动车产销第一大国，机动车污染已成空气污染的重要来源，是造成灰
霾、光化学烟雾污染的重要原因。监测表明，我国城市空气开始呈现出煤烟和机动车尾气复合污染的特点，直接影响群众健康。2011年，全国机动车排放污染物
4607.9万吨，比2010年增加3.5%，其中氮氧化物(NOx)637.5万吨，颗粒物62.1万吨，碳氢化合物(HC)441.2万吨，一氧化碳
(CO)3467.1万吨。
汽车是污染物总量的主要贡献者，其排放的NOx和PM超过90%，HC和CO超过70%。
按车型分类，全国货车排放的NOx和PM明显高于客车，而客车CO和HC排放量则高于货车。按环保标志分类，仅占汽车保有量16.4%的“黄标车”却排放
了63.7%的NOx、86.6%的PM、55.9%的CO和60.4%的HC。
环保部新闻发言人陶德田表示，环境保护部将进一步加大工作力度，会同有关部门，从行业发展规划、城市公共交通、清洁燃油供应等方面采取综合措施，协调推进“车、油、路”同步发展，大力防治机动车尾气排放对大气环境和人民群众健康的影响。China has pledged to vigorously curb
vehicle exhaust emissions after hazardous air pollution has shrouded
parts of the country for several straight days, the environmental
watchdog said Monday.
China will take effective measures to limit the total amount of nitrogen
oxide emitted by vehicles and intensify supervision over the
production, use and elimination of motor vehicles, said Tao Detian,
spokesman for the Ministry of Environmental Protection.
The ministry will make more efforts to step up urban public transport
development and promote the use of clean energy to cut vehicle exhaust,
which is the main factor contributing to the smog in cities, Tao said.
According to data from the country's auto industry, China remained the
world's largest producer and market for automobiles for the fourth
consecutive year in 2012, with auto sales at 19.31 million units and
production at 19.27 million vehicles.
Carbon monoxide, nitrogen oxide and other pollutants emitted by motor
vehicles are among the major contributors to the air pollution problems
like smog and acid rain that frequently occur in some Chinese cities.
Heavy fog has enveloped a large portion of east and central China in
recent days, causing highway closures and flight delays in several
provinces.
Beijing's air has been heavily polluted. Readings for PM2.5, or airborne
particles with a diameter of 2.5 microns or less -- small enough to
deeply penetrate the lungs -- were as high as 993 micrograms per cubic
meter of air on Saturday evening.
