| 摘 要： | 通过电感耦合等离子体质谱(ICP-MS)对北京、太原、苏州、成都四城市40份成人血铅进行了浓度及其同位素比值的同时测定,以考查不同地区血铅的地区性特征。结果显示工业城市成都、太原血铅浓度高于非工业城市北京、苏州,说明工业污染仍是造成高血铅的重要因素;同位素测试结果显示各城市血铅同位素比值具有特征分布区域和分布特点,食源性铅可能已取代大气铅成为北京等发达城市血铅的主要来源,全球化带来的的物产多样化削弱了一些发达城市铅污染的地区特征。

| Abstract: | Blood lead is a reflection of environment lead in vivo,its concentration could be used to assess lead exposure of environment quantitatively,and its isotopic ratio could be used to fingerprint environment source qualitatively.In the present study,concentrations and isotopic ratios of blood lead(BPb) of four cities in China were measured by ICP-MS for the first time.The regional effects of BPb in four Chinese cities were observed in our study.The BPb levels of industrial cities(Taiyuan and Chengdu) are highe... |
