Levels of Heavy Metals in Soil, Water and Vegetables around Industrial area in Bauchi, Northeastern Nigeria

This study examined the levels of heavy metals in soil, water, and vegetables (amaranthus, hibiscussabdariffa, allium cepa leaves) around industrial area Bauchi, Northeastern Nigeria. The composite samples were collected determine level (Mn, Zn, Cd, Pb, As) using Atomic Absorption Spectrophotometer (AAS). decreased order Mn > Zn Pb Cd respectively. Among vegetables, amaranthus had highest followed by leaves hibiscus sabdariffa. obtained below tolerance recommended world health organization (WHO). bio-concentration factors for studied one except amaranthus. daily intake was found to be children estimated 1.149 mg/person/day. Health risk index amaranthus, sabdariffa both adults above 1, adults, signifying provable risks consumption area. Therefore, these as food could pose a hazard, regular monitoring is prevent metal accumulation with their associated implications consuming public.
