Sample of waste water from Kasuwan Shanu abattoir was collected for determination of levels of some heavy metals (Cd, Fe, Mn, Hg, Zn, Ni, Cr) and physicochemical properties. The sample was analyzed according to standard procedures. The results of the study revealed the order of the concentrations of the studied heavy metals as Ni > Zn > Mn = Hg > Cd > Fe > Cr. The levels of the heavy metals were above the permissible limits set by WHO except Fe, Mn and Zn which fall within acceptable limits. The physicochemical parameters were also within the permissible limit except turbidity and electrical conductivity values which stood at 34 FTU and 1784 µS/cm respectively, against the 5 and 1000 µS/cm standard limits for their discharge.
