DETERMINATION OF SOME HEAVY METALS IN SELECTED COSMETIC POWDERS
Abstract
we assessed the levels of some heavy metals in different Cosmetic powders sold at local shops in Kano. The Cosmetics Powders were purchased from various shops at different locations in Kano. The Cosmetics were analyzed for heavy metals (Cadmium, Chromium, Copper, lead and Zinc) after digestion with concentrated acids HNO3, HCl in ratio 1:3. The concentrations of the selected heavy metals were determined in triplicate using a flame Atomic Absorption spectrophotometer. The samples analyzed contained a detectable amount of Metals of interest. The concentration of the heavy metals in the samples ranged from 0.012 to 4 .156 mg/Kg. It is obvious from the present study that the use of Cosmetic products exposes users to low concentrations of toxic heavy metals which could constitute potential health risk to users since it has been known that heavy Metals can accumulate in the biological system over time and are known to induce skin problems or diseases such as Cancer. Further research to better understand the sources of heavy metals in Cosmetic products is recommended.
