Abdulhadi Y ^[2] | Salisu A ^[2] | Kawo A. H.

Abstract: The effects of environmental pollution associated with industrial effluents of some industrial establishments in Kano, Nigeria were examined. The physico-chemical parameters of pH, temperature, turbidity, color, odor, suspended solids, total dissolved solids, electrolytic conductivity, dissolved oxygen, biochemical oxygen demand, chemical oxygen demand, alkalinity, oil and grease, lead, sulphide, chloride, chromium, phenol, nitrate, phosphate and sulphate were examined in some major establishments involved in sack-making activities, tanning, pharmaceutical and beverage productions. The microbiological parameters examined included the coliforms and Escherichia coli. The values obtained were compared with the State and Federal Ministries of Environment standards for effluent discharge into either water bodies or soil (land). It was generally found that all the parameters of the treated effluents examined were generally below the specifications of the State Interim Primary Effluent Standards and Federal Ministry of Environment standards for quantitative industrial effluent discharge into either the land (soil) or water bodies. The implications of these pollutants on the ecosystem were discussed in line with sustainable clean environment.
