摘要
采用高分辨电感耦合等离子体质谱技术(HRICPMS)分析了48个不同季节大气气溶胶颗粒样品中铅同位素丰度(A)比值,为中国城市铅污染源研究提供数据。样品采自中国北京和山东长岛地区(2002～2003年期间不同季节)。A(206Pb/207Pb)和A(208Pb/207Pb)的10次测定精密度为0.05%～0.19%RSD。
The results of lead isotope ratios in atmospheric aerosol determined by HR-ICP-MS is provided for the purpose of monitoring and assessment of current lead pollution in the urban atmosphere in China. Samples were collected from two locations in the urban areas of Beijing and Changdao Shandong, China at different seasons in 2002 and 2003. The relative standard deviation of ten measurements for A(^(206)Pb/^(207)Pb) and A(^(208)Pb/^(207)Pb) at different concentration levels was in range of 0.05%～0.19%.
