“…The concentrations of Cr, Cu and Pb were highest in the effluent at 20 m (2.69±0.32 mg/l, 2.51±0.40 mg/l and 2.69±0.70 mg/l respectively). The concentrations of the Cd, Cu, Pb and Zn in the effluents from NGL were higher than 0.38 mg/l, 0.37 mg/l, 1.03 mg/kg and 1.87 mg/l respectively reported in polluted river dam in Jos [17] . The results of Cd and Zn for GCL were within the range of 0.01-0.38 mg/l and 0.95-1.87 mg/l reported respectively for both metals in Jos.…”

The study assessed the environmental quality around industrial areas of Jos and Kaduna, north-central Nigeria using heavy metals concentration in waste water (effluent) and atmospheric dust. Effluent and moss samples collected in replicates from two industrial sites in Jos and Kaduna were analyzed for Cd, Cu, Pb, Zn and Cr using Atomic Absorption Spectrophotometer (Buck Scientific -210 VGP). The concentrations of heavy metals in the effluents varied with site and location. Heavy metals concentrations were highest at the point of drain (0 m) across the industrial sites. Heavy metals contaminations were observed in mosses across the sites, with NGL (Jos) recording the highest levels. The pollution load indices reflected depletion in environmental quality across the industrial sites.
