摘要：The water quality parameters such as temperature, pH, salinity, conductivity, EC, TDS, TSS, DO, COD, BOD and E. coli were observed in the surface water and Cr, Cu, Zn, Pb, Ni, Cd, Mn, Hg, Fe and As were observed for surface water and sediment in dry and wet seasons for the Turag River. The mean value of observed parameters for surface water shows that the Turag River is highly polluted by pH (8.85), EC (1117.17 μS), DO (0.98 mg/L), COD (288.33 mg/L), BOD (157.67 mg/L), E. coli (<18000 cfu/100 mL), Cr (0.056 mg/L), Pb (0.015 mg/L) Mn, (0.7 mg/L) and Zn (0.30 mg/L) and for surface sediment is highly polluted by Cr (127.1 mg/kg), Cu (223.9 mg/kg), Zn (1419.4 mg/kg), Pb (26.3 mg/kg), Ni (35.3 mg/kg), Hg (624.6 mg/kg), Fe (12721.34 mg/kg) and Mn (313.3 mg/kg). Geoaccumulation status shows that surface sediment is strongly to extremely polluted by Zn.
