The Priorities of Vehicle Emission Control in the future 未来机动车污染控制优先考虑的问题 Part 1 The Situation of Chinese Vehicle Pollution 中国机动车污染状况 In 2004, 210 cities exceeded the Class 2 limit values of the National Ambient Air Quality Standard (NAAQS) within the total 342 monitored cities. In which 69 cities exceeded the Class 3 limit. 　　2004年,受监测的342个城市中有210个城市的空气质量超过了国家环境空气质量标准的二级标准。其中有69个城市超出了三级标准。 There was 2/3 population in urban areas where air quality exceeded the limits of NAAQS.. 2/3的城市居民生活在空气质量不达标的环境中。 The major problems include SO2 and PM. SO2和颗粒物成为主要的问题。 In the past 10 years, air pollution in urban areas caused by coal burning had been under control in most regions in China. 　　过去10年中，中国大部分区域中由于燃煤而造成的城市空气污染已逐步得到控制。 Due to the fast growth of vehicles population in the recent 10 years, esp. in large cities, air pollution from vehicle emission has become increasingly significant. Days and hours NOx and O3 concentrations exceeding NAAQS increased continuously; most diesel vehicles smoked much; road dust resuspended by traffic;high concentrations of CO, HC and SO2 along roadsides. 　　近10年来，由于机动车保有量的快速增长，大城市中机动车污染显著恶化。 NOx 和 O3 浓度持续超标；柴油车冒黑烟问题严重；道路交通扬尘难以解决；道路两侧CO、HC和SO2污染严重。 Air Pollution Situation in Beijing City北京空气污染状况 In summer and autumn 2004, Beijing had 67 days and 285 hour
