2011-2016年贵州省市售化妆品汞含量测定研究

Determination of mercury in commercial cosmetics in Guizhou province in 2011-2016

对2011—2016年贵州省市售多类化妆品中汞含量进行检测分析,以了解全省市售化妆品中汞的分布情况,并分析其安全风险。实验采用微波消解法对样品进行预处理,氢化物原子荧光光度法对样品中的汞含量进行测定。结果表明,832批次样品中512批次检出汞,检出率61.5%;40批次样品汞含量超过国家标准,超标率4.8%;研究出现汞超标的样品中,国产宣称美白或祛斑类产品超标率最高,为11.5%,该类超标产品中83.3%超过国家标准1 000倍。

The content of mercury in the cosmetics sold in the market of Guizhou province in the years from 2011 to 2016 was tested and analyzed to understand the distribution of mercury in cosmetics sold in the province and to analyze its safety risk. The samples were pretreated by microwave digestion. Hydride generation atomic fluorescence spectrometry was used to determine the content of mercury in samples. The results showed that mercury was detected in 512 batches among the 832 batches of samples, thus the detection rate was 61.5%. There were 40 batches of samples whose content of mercury had exceeded the national standard, thus the exceeding rate was 4.8%. The exceeding rate was highest （11.5%） for the products declaring whitening or freckle removing, 83.3% of which had exceeded the national standard by 1000 times.
