摘要：Effluent (wastewater) were collected from a metal finishing company, Zaria -Nigeria over a period of 2 years. Physical and chemical characteristics of the effluent were determined using standard methods. The means of: pH (4.5), TD S (4348.00mg/l), TSS(395.00mg/l), NO3-N(84.50mg/l), SO42-(1992.67mg/l), ClG(823.87mg/l), Cu(7.97mg/l), Pb(1.10mg/l), Ni (11.85mg/l) and Zn(5.06mg/l) were far outside the limits set by FEPA for the discharge of wastewater from metal finishing company into surface water. Even though FEPA limits does not include electrical conductivity, total alkalinity, total hardness, total solids, and dissolved oxygen for this category of industry, the values of these parameters obtained for the company effluent samples were obviously very high for wastewater to be discharged into surface w ater.
