摘　　要：用超细玻璃纤维滤膜收集城市交通干道空气中的铅 ,硝化后使用石墨炉原子吸收分光光度法测定。本方法具有灵敏度高 ,精密度和准确度较好等优点。铅平均浓度在 10 .5 7～ 69.67μg/L时 ,其相对偏差在 0 .47%～ 5 .7%之间 ,标准差在 0 .18%～0 .3 3 %之间 ,CV在 0 .47%～ 3 .0 3 %之间 ,标准曲线的相关系数为 0 .998。The plumbum in air of a urban traffic main road was collected by filter film of super thin glass fiber and determined by graphite AAS. The determined data showed that when the concentration of plumbum was 10.57～69.67 μg/L, the relative deviation range was 0.47%～5.7%,the standard deviation range was from 0 18 to 0 33, the variations range was from 0.47% to 3.03% and the correlation coefficient was 0.998. Therefore this method had high sensibility, high accuracy and high precision.\;
