摘　　要：采用电感耦合等离子体质谱检测法对贵州省9个市(州)线下实体经营企业的100批次祛斑美白类、62批次宣称隔离功效的彩妆类、30批次爽身粉及156批次涂抹式面膜类化妆品中锂等37种元素进行含量测定并对数据进行分析。质量浓度范围在0~100μg/L(汞为0~4μg/L)时,37种元素线性相关系数均大于0.999,回收率为88.7%~115.3%,检出限为0.004~4μg/kg,定量限为1~80μg/kg。结果发现,含元素种类较多且含量较高的产品,成分中大多含有土壤、矿物及植物提取物。Inductively coupled plasma mass spectrometry was used to determine the content of 37 elements such as lithium in 100 batches of skin-whitening/anti-freckle cosmetics,62 batches of makeup base cosmetics claiming isolation effects,30 batches of talcum powders and 156 batches of smear-style masks from offline entity enterprises in 9 cities(prefectures)of Guizhou Province and the data were analyzed.In the range of 0-100μg/L(Hg:0-4μg/L),the linear correlation coefficients of 37 elements were greater than 0.999,and the recovery rates were 88.7%-115.3%.The detection limits were 0.004-4μg/kg and the quantitative determination limits were 1-80μg/kg.The results showed that the most of cosmetics containing more kinds and higher levels of elements contained soil,mineral and plant extracts in their compositions.
