摘要
分析了不同高度的大气中铅尘含量。结果表明 ,铅尘在大气中的分布随着高度的降低而大幅度增加。儿童身高刚好在大气铅浓度最高的范围内 ,这也正是儿童血铅超标比例大的主要原因。马路边的铅尘大于公园绿地上的铅尘 ;干旱多尘土季节大气中的铅尘大于雨季。
Lead-dust was analysed in atmosphere with different height.The result shows that lead-dust largely adds in atmosphere scope with degression of height.The children's height is just in atmosphere with high lead field.This is also the chief cause of children's lead poisoning.Lead-dust on sideway is larger than green-park.In drought season lead-dust in atmosphere is larger than that in rainy season.
