Abstract
This study aimed to determine the levels of heavy metal(loid)s in local and
imported cosmetics purchased from the Kejetia market and to conduct their health
risk assessment. Seven (7) metal(loid)s (Pb, Cd, As, Fe, Ni, Cr, and Hg) were analyzed
in twenty-one (21) cosmetic samples. Atomic absorption spectroscopy (AAS) was
used in this study. Some of the metal(loid)s in imported cosmetic samples were
higher than those found in local cosmetic samples. However, there was no signifi cant difference between the concentrations of the metal(loid)s in both local and
imported cosmetic samples. The margin of safety (MoS) values for all the metal(loid)
s in the cosmetics sample were below the WHO standard of 100. The HQ and HI
values for almost all the metal(loid)s in the cosmetic samples were greater than
their permissible limit of 1, suggesting that there may be health risks associated
with using cosmetic samples for the sensitive sub-population. On the other hand,
carcinogenic risk (CR) for Cr and As in local and imported cream and lotion were all
higher than the tolerance levels. Moreover, from the results, the Pb, Cd, and Hg
concentrations were higher than the acceptable permissible limits set by the various
regulatory bodies. Cosmetic manufacturing industries are encouraged to adhere to
the permissible limits set by regulators. We admonish the regulatory agencies to
unforce regulations on permissible limits of heavy metals in cosmetics
