Determination of Cd, Co, Cr, Ni and Pb metals in lipsticks samples by Flame atomic absorption spectrophotometry (FAAS)

Abstract

The study was conducted this work to analyze levels of toxic metals in lipsticks specifically sold in the Bhopal area. Acid digestion process was used to prepare the samples and to quantify the levels of heavy metals, including Cd, Co, Cr, Ni, and Pb Flame Atomic Absorption Spectrophotometry was used. Calibration curves were prepared with good linearity for accurate measurement of concentrations of these metals. All heavy metal observed were within the allowable limit. To assess the health risks, Average daily dose (ADD) and Hazard quotient (HQ) (Ingestion) for all the lipstick samples were calculated. Among these samples, three samples shows higher values among them one belonged to a branded category, while the remaining two were from the non-branded category. These particular Lipsticks samples exhibited higher HQ values (higher than 1), indicating a probable hazard linked of toxic-metals.
