Abstract
Chemical analysis of the effluents of the industrial area in Ibadan, Southwestern Nigeria, and their effect on three communities were evaluated. The degree of pollution was ascertained by determination of the concentration of 12 metals including Pb, Cu, Ni, K, Cd, Fe, Zn, Ca, Cr, Mn, Na, Mg, a specific nonmetal phosphorus, as well as chloride (Cl) and nitrates (). The study established the presence of metals in concentrations higher than the recommended limits in effluent discharges in all the samples in the study area.
