摘　　要：研究了沈阳市一环及其内主要街道在不同粒径区间灰尘中Pb的空间分布特征,共采集61个样品。分别测定了灰尘在100～125,63～100和小于63μm这3个粒径区间中Pb的含量。结果表明:此3个粒径区间中Pb含量相近,63～100μm粒径中Pb含量稍高;铁西区污染程度处于市内5区之首。Sixty one samples were collected to investigate the space distribution of lead in different granularity of street dust from main streets of Shenyang. The samples were sieved into three particle size ranges： 100-125,63～100μm and 〈 63μm, then the lead concentrations in these three granularities were analyzed. The results indicated that the concentrations of lead in these three granularities approached to each other, and the highest one was in 63～100μm which was a little higher than others. Tiexi district was the most polluted one in the five districts.
