摘　　要：在仪器最佳条件下,样品经前处理后,采用ICP-MS和AAS2种方法测定无公害大气总悬浮颗粒物中铅及其化合物的含量,最终2种方法的测定结果一致,但ICP-MS线性范围宽、检出限低、精密度好。Under the optimal conditions of the instrument,samples were pretreated.The total lead in pollution-free atmospheric total suspended particulate matter was determined by ICP-MS and AAS.But the results of ICP-MS method shows wider linear dynamic range,lower detection limit,better precision.
