**4. Heavy metal profile**

### **4.1. Water**

Concentrations of heavy metals in the water samples collected from different location have been summarized in Table 3. It is clearly evident from the table that heavy metals were consistently higher in zone 2 compared to zones 1 and 3. Cr content was markedly higher among the metals in zone 2 followed by zone 1. The concentration of heavy metals in water samples ranged from 0.018 – 0.095 mg Pb l-1, 0.025 – 0.341 mg Cd l-1, 0.47 – 1.76 mg Zn l-1, 0.27 – 1.58 mg Cu l-1, 0.001 – 0.005 mg Co l-1, 0.80 – 9.37 mg Cr l-1 and 0.078 – 0.32 mg Ni l-1. As was not detected in any sample.
