鱼儿离不开水,人类离不开空气。空气质量对人类的重要性自然足不言而喻的。汽车排放的尾气对空气质量的影响是非常巨大的。一辆老旧汽车的尾气污染物排放量相当于4辆已达到欧Ⅰ排放标准的机动车的排放量,相当于7辆达到欧Ⅱ排放标准的新车的排放量和14辆达到欧Ⅲ排放标准的新车的排放量!本期,我们请有关专家来解读这个听上去很专业,但与每个人的生活又都关系如此密切的话题:即将到来的欧Ⅲ距离举办2008年奥运会的日子越来越近了,可对首都北京来说却并不那么轻松。北京的空气质量近年来虽在逐步改善,但是离“绿色奥运”的要求仍有很大差距。据测算,约60%的大气污染物来自于汽车尾气。怎么
Fish can not do without water, human beings can not do without air. The importance of air quality to human beings naturally goes without saying. The impact of car exhaust on the air quality is enormous. The emission of exhaust pollutants of an old car is equivalent to the emission of four vehicles that have reached Euro I emission standard, which is equivalent to the emissions of seven new cars meeting Euro II emission standard and 14 vehicles meeting Euro III emission standard This issue, we ask the experts to interpret this sounds very professional, but with everyone’s life are so closely related topic: the upcoming Euro Ⅲ from the 2008 Olympic Games day more and more It’s not that easy for the capital, Beijing. Although the air quality in Beijing has been gradually improved in recent years, there is still a long way to go to meet the requirements of the “Green Olympics.” It is estimated that about 60% of air pollutants from the vehicle exhaust. how
