| Abstract: | Objective ] The research aimed to evaluate the pollution status of lead in Liuchong River of Guizhou Province. Method ] The graphite furnace atomic absorption spectrometry was used to analyze the quality, especially the lead contents of three water samples in Liuchong River, Guizhou Province. Result] The results showed that recoveries were between 99.67% and 103.3%. The RSD was between 0.8 and 1.8. The concentrations of three samples were 2.93,2.86 and 2.76 μg/L, respectively. Conclusion] This research proved that the contents of lead in Liuchong River were low. While the river pollution caused by higher lead contents still should be emphasized. |
