  Abstract: This study employs advanced analytical techniques to assess heavy metal contamination (Pb, Cd, Cr, Ni, Zn) in 18 commercially available eyeshadow products (local and imported) from Owerri Metropolis, Nigeria. Quantification was conducted using atomic absorption spectroscopy (AAS), while risk evaluations incorporated chemometric modeling approaches. Results revealed significant contamination in locally manufactured brands, particularly those containing calabash chalk (Nzu) as a base ingredient. Lead and nickel concentrations reached 166.58 ± 6.5 …
