Abstract: The effluent and receiving water and soil quality from six chemical industries in Ibadan metropolis was investigated. The heavy metal, minerals and physicochemical properties of the effluents and receiving waters were determined using standard methods. Results show that Cobalt, chromium, copper, Iron, magnesium, manganese, zinc and lead contents of effluents range between 0.17-0.39, 0.04-0.11, 0.01-0.06, 0.04-0.16, 0.09-1.47, 0.06-0.90, 0.12-0.14 and 0.15-0.37 mg L 1, respectively. The heavy metal contents the effluents fall within recommended range. Iron, lead and zinc levels are significantly (p< 0.05) higher in environments around compared with the control samples. The effluents are rich in inorganic compounds, free ammonia, phosphates, chlorides and nitrates. Significant decreases were recorded in the electrical conductivity and total solids of receiving waters while significant increases were recorded in hardness, dissolved solids, BOD and COD. The levels of calcium and zinc were low and values within the critical limit thus posing little threat to ground water quality.
