Determination Of Heavy Metals In Some Cosmetic Products Commonly Used Among Students Of Kaduna Polytechnic

ABSTRACT

The toxicity of heavy metals to humans as a result of long term exposure to pollutants consumer products such as cosmetics and other pollutants has been established. In this study, the levels of heavy metals in different cosmetic products commonly used among Kaduna Polytechnic students were assessed. The cosmetics were analyzed for heavy metals (chromium, copper, nickel and lead) using Atomic Absorption Spectrophotometer (AAS) after digestion with concentrated HNO3 and HCl acids. The concentrations of the selected heavy metals were determined in duplicates. All the samples analyzed contain detectable amount of the selected heavy metals which range from 0.02813 – 13.6628ppm in Lipstick, 2.4162 – 81.7835ppm in Powder and 0.0019 – 39.2720ppm in Soap although within the allowed limits. It is confirmed from this study that the use of cosmetic product exposes the users to low concentrations of toxic heavy metals which may lead to potential health risk to such users, since the metals can accumulate in the body over time. Recommendations on how to curb this challenge was also given.
