摘要

进行这项研究是为了评估在联合王国(英国)、美利坚合众国(美国)、印度和中华人民共和国(中国)生产并在坦桑尼亚达累斯萨拉姆销售的一些市售化妆品中的重金属含量。来自上述国家的面霜、美容皂、口红和身体乳从达累斯萨拉姆当地市场购买,并采用火焰原子吸收光谱法(FAAS)分析方法测定铅(Pb)、镉(Cd)和铜(Cu)的含量。结果表明,口红样品中Pb含量最高,为23.36µg/g, Cd含量最高,为23.30µg/g, Cu含量最高,为22.91µg/g。美容皂样品中的最高浓度为21.99µg/g Pb, 0.98µg/g Cd和18.8µg/g Cu。面霜样品中Pb含量最低,为6.52µg/g, Cd含量最低,为0.16µg/g, Cu含量最低,为3.75µg/g。体乳未检出铅、镉;Cu含量较高,可达1.4µg/g。不过,被评估的产品含有有毒的重金属,浓度没有达到令人担忧的水平。建议对这些产品的健康风险进行进一步的研究和分析,并必须高度重视生产过程中的重金属。

Level of selected heavy metals in some commercially available cosmetic products in Dar es Salaam, Tanzania
The study was conducted in order to assess heavy metal content in some commercially available cosmetics products that are manufactured in United Kingdom (UK), United States of America (USA), India and the Peoples Republic of China (PRC) and sold in Dar es Salaam, Tanzania. Face creams, beauty soaps, lipsticks and body lotions from the mentioned countries were purchased from local markets in Dar es Salaam and analytical procedures were employed to determine the contents of lead (Pb), cadmium (Cd) and copper (Cu) using Flame Atomic Absorption Spectrometry (FAAS). The results showed that lipstick samples contained the highest Pb at 23.36 µg/g, Cd at 23.30 µg/g and Cu at 22.91 µg/g. The highest concentrations in the beauty soap samples showed 21.99 µg/g Pb, 0.98 µg/g Cd and 18.8 µg/g Cu. Face cream samples contained the least contents of Pb at 6.52 µg/g, Cd at 0.16 µg/g, and Cu at 3.75 µg/g. In body lotions, no Pb and Cd were detected; in contrast, the contents of Cu was high (up to 1.4 µg/g). The products evaluated contained toxic heavy metals, though, not at an alarming concentration. Further research and analysis on the health risks of these products is proposed and extreme attention must be given to heavy metals during manufacture.
