Abstract:

flame-less atomic absorption spcctropholometry technique lias been used to determine mercury concentrations in 14 skin-lightening creams and soaps commonly sold in the Kenyan market and 10 in the Norwegian market. The use of borohydride or stannous chloride as the reducing agents for mercuric salts gave different results. When slannous chloride was used as the reducing agent the range of mercury content was 222 to 4920 jjg/kg. When borohydride was used as the reducing agent the range of mercury content was 0.95 to 1121.86 |jg/kg. The difference in results has been attributed to the difference in digestion modes and the ability of the boric acid to encapsulate the mercuric salts. In general the Kenya products had slightly higher mercury content.
