Concentrations and probable health risks of potentially toxic metals (Pb, Cd and Cr) in some Nigerian lipstick products

Paints and coatings add aesthetics to our daily lives. Their demand has increased due to urbanization and has led to an increase in lead (Pb) in the ecosystem and its potential risks to health. Pb is toxic and has no safe levels for children. This study examines the levels of lead in paints from major paint distribution markets in Southwestern Nigeria. Analyses were done using wet acid digestion and graphite-furnace atomic absorption spectrophotometry (AAS 220GF). The levels of Pb (µg/g ± SD in dry weight) ranged from 4,790 ± 40–79,300 ± 80 in a light silver and matte black automobile paint, while in the decorative paints, samples ranged from 2,220 ± 10–91,500 ± 49 in a cream (plastic) and black (enamel) color. The highest level of Pb in the plastic paints was up to 142 fold and 944 fold, while in the enamel, 153 fold and 1017 fold, above the 600 µg/g and 90 µg/g recommended limits by the United States Environmental Protection Agency and Consumer Product Safety Commission, respectively. Lead compounds are pigments used to improve the color quality of paint formulations. The present study poses a serious concern. As a result, there is a need for greater public awareness and strict enforcement of the ban on leaded paint by government regulatory bodies.

The use of cosmetic products is expanding globally, and with it, so is the range of chemical substances employed in their production. As a result, there is also a higher risk of intoxication, allergic reactions, prolonged chemical exposure, adverse effects, and indiscriminate use. Cosmetic products can contain more than 10,000 ingredients. Most users of synthetic cosmetics are unaware of the harmful effects if they even are. However, it is linked to many diseases like cancer, congenital disabilities, reproductive impairments, developmental systems, contact dermatitis, hair loss, lung damage, old age, skin diseases and reactions, allergies, and harm to human nails. Many beauty products also create a high demand for natural oils, leading to extensive and intensive cultivation, harming natural habitats through deforestation, and contaminating soil and water through pesticides and fertilizers. The adverse effects of hazardous substances in synthetic cosmetics extend beyond human health and influence ecosystems, air quality, and oceans. Thus, this review aims to assess the environmental and health impacts of cosmetics using published scientific articles. The study used a systematic review based on Scopus, Science Direct, Web databases, Scholar Google, and PubMed. The results of this review showed that the formulation of cosmetics until the disposal of their containers could adversely affect environmental and human health.
