从100个日本普通住宅收集的室内灰尘中的25种元素的水平进行了测量。对多元素数据进行因子分析，探讨了室内灰尘中Pb（中位浓度49.1mg/kg）的来源。提取了6个因子，Pb与Sb、Sn对第5因子的负荷较大，表明焊料（Sn）、塑料和金属（Sb）可能是日本住宅灰尘中Pb的来源。没有发现显着的负荷土壤相关的因素，表明非显着的贡献，铅在跟踪土壤。7种重金属（Cd、Cu、Mo、Pb、Sb、Sn和Zn）在室内灰尘中的浓度超过地壳丰度的10倍。这些元素的健康风险，儿童通过摄入房屋灰尘估计的基础上，与每日可耐受摄入量的比较，发现是不显着的大部分元素。
The levels of 25 elements in house dust collected from 100 general Japanese residences were measured. Factor analysis was applied on the multi-element data to explore source of Pb (median concentration 49.1 mg/kg) in house dust. Six factors were extracted and Pb was found to have great loading on the fifth factor with Sb and Sn, suggesting solder (Sn), and plastic and metals (Sb) may be the sources of Pb in the house dust of Japanese residences. No significant loading was found on soil-related factors indicating non-significant contribution of Pb in track-in soil. Seven heavy metals (Cd, Cu, Mo, Pb, Sb, Sn, and Zn) were found in house dust at >10 times more condensed than crustal abundance. Health risk of these elements to children via the ingestion of house dust was estimated based on the comparison with tolerable daily intake and found to be non-significant for most of the elements.
