| 摘 要： | 通过采集南宁市居民室内积尘，采用石墨炉原子吸收法进行铅含量的测定，根据JJF1059—1999〈〈测量不确定度评定与表示》对影响测量结果的不确定度分量进行了量化的计算，结果表明影响铅含量测定不确定度的主要因素为试样制备和校准曲线绘制，在该样品铅含量测定中，室内积尘中铅含量为21．4mg／kg，其扩展不确定度±2．78ms／kg。

| Abstract: | With resident indoor dust from Nanning City, this study adopts graphite furnace atomic absorption method to deter- mine lead content. According to JJF 1059 - 1999 ＂Evaluation and Expression of Uncertainty in Measurement＂, the uncertainty in component results were calculated quantitatively. The results show that the main factors influencing the uncertainty of lead content are the sample preparation and calibration curves plotting. In this study, the lead content in indoor dust is 21.4 mg/kg with ex- tended uncertainty of±2. 78 mg/kg. |
