Lead compounds in traditional eye cosmetics (“kohls”) available in Morocco
This study was undertaken in order to determinethe chemical composition of potentially lead-toxictraditional eye cosmetics (“kohls”) available in Morocco. Atotal of 9 kohl samples were obtained in the souks of varioustowns in Morocco. The techniques of X-ray powderdiffraction (XRPD) and low vacuum scanning electronmicroscopy (LVSEM) were used to analyse the samples.Overall, it was found that 5 (56 percent) of the samplescontained a lead compound (galena, PbS) as the maincomponent; with a further 2 samples having galena presentas a minor component. The other (4) main componentswere found to be either calcite or aragonite (i.e. CaCO3).
