Abstract:To describe the characteristics for the content and the distribution of atmospheric lead in urban China, the articles on atmospheric heavy metal contents in Chinese cities publicated from 2000 to 2012 were searched and collected through the search engines of CNKI, Wanfang, CQVIP, Science Direct, Google Scholar and PubMed etc. Based on the uniform criteria, 69 articles were selected for the further analysis. The atmospheric lead contents were reported in 42 cities of 30 provinces and included more than 5,489 samples. Atmospheric lead concentrations were expressed by the lead concentrations in PM10. The lead concentrations by those in PM2.5 and in TSP were transferred, including the limits of the national ambient air quality standards (NAAQS). The weighted mean of atmospheric lead level in urban China was (256.5±192.0) ng/m3. The atmospheric lead levels in 18cities (42.9%) were higher than 272.5ng/m3, the limits of NAAQS (GB3095-2012) in PM10, and the average was (551.0±350.3) ng/m3. The levels of lead in Changsha in Hunan province, Shaoguan in Guangdong province, Shengyang in Liaoning province, Yongxiu in Jiangxi province, Xi'an in Shanxi province and Hulu island in Liaoning province were 554.4, 637.0, 638.8, 764.1, 1018.6 and 1721.2ng/m3, respectively, these were higher than the seasonal limit of NAAQS (545.0ng/m3). The results also showed that levels of atmospheric lead in developed regions, such as Beijing-Tianjin-Tangshan economic zone, Circum-Bohai-Sea region and Pearl River Delta, were higher than those in other regions. The atmospheric lead contents in winter-spring were 1.2~1.9times as high as those in autumn-fall in north cities in China, while there were no significant differences in southeast coastal cities. It was showed that lead contents decreased remarkably in Guangzhou, Shanghai, Beijing and Chengdu since 2003. These results suggested that the atmospheric lead contents in urban China were much higher that those in developed countries, although the levels of lead showed the decreased trend.
