【摘要】：为了解中国城市儿童血铅含量变化趋势及其影响因素,收集了1997—2010年166组城镇儿童血铅数据、23个土壤铅含量与25个城市年均PM10数据。统计结果显示,1997—2000年,中国儿童血铅年平均值逐年升高,平均值为98.56μg·L-1,自2000年禁用含铅汽油之后,血铅年平均值总体呈下降趋势,2001—2010年中国儿童血铅平均值为69.61μg·L-1。从不同省份来看,血铅含量随时间总体呈下降趋势,北京等省市已降至较低水平。相关分析表明,城市儿童血铅含量与城市土壤铅含量和大气颗粒物浓度有显著的正相关关系,城市土壤和大气颗粒物仍是儿童铅暴露的重要途径。
[Abstract]:In order to understand the changing trend and influencing factors of blood lead in urban children in China, the data of blood lead in 166 groups of urban children from 1997 to 2010, 23 soil lead levels and 25 cities average annual PM10 data were collected.The statistical results show that the annual average of blood lead in Chinese children increased year by year from 1997 to 2000, with an average value of 98.56 渭 g / L ~ (-1). Since the prohibition of leaded gasoline in 2000, the annual average value of blood lead in Chinese children was 69.61 渭 g / L ~ (-1).From different provinces, the blood lead content showed a general downward trend with time, Beijing and other provinces and cities have fallen to a lower level.The correlation analysis showed that there was a significant positive correlation between the blood lead content of urban children and the content of lead in urban soil and the concentration of particulate matter in the atmosphere. Urban soil and atmospheric particulate matter were still important ways for children to be exposed to lead.
