The GB/T 11739-1989 standard is suitable for the determination of lead concentration in the atmosphere of residential areas, using Atomic absirption spectroscopy-tometry, AAS. It is suitable for the determination of lead concentration in total suspended particulate (TSP) and respirable particulate matter (PM), with high Sensitivity and low detection limit. Methods The samples were treated with dilute nitric acid, and the characteristic spectral lines of lead were used for quantitative analysis. It is suitable for large Flow rate sampling and respirable particulate matter (PM) sampling. The standard describes in detail the reagents, equipment and operation steps required for the experiment, providing a scientific basis for the monitoring of lead content in the atmosphere.
