Description
Summary:[Display omitted] •Metal content of 27 household hygienic products available in Nigeria was determined.•SED values for metals in these products were below tolerable intake levels.•MoS values indicate that they are reasonably safe for human use.•However, products contained significant amounts of toxic and allergenic metals.•Effluents from use of products are likely sources of metals to the environment. This study presents data on the levels and risk of human exposure to Cd, Pb, Cr, Ni, Cu, Co, Mn, Zn and Fe in some popular brands of household hygienic products (HHPs) available in Nigeria. The HHPs were digested with a mixture of HNO3, HCl and HClO4 in a ratio of 1:3:1 and the concentrations of the selected metals were quantified by atomic absorption spectrophotometry. The metal concentrations (in μg g−1) in these products ranged from 0.4 to 5.4,
