Quantification of Heavy Metal Accumulation in Water and Edible Fish Tissue Samples Collected From the River Tawi, Jammu, India

The present study estimated the concentration (in ppm) of heavy metals Zn, Fe, Cu and Pb in water samples edible tissue Labeo boga; both collected from non polluted (Station I) II) locations river Tawi, Jammu, India. mean (Zn, Cu, Pb) at Station I were 0.048±0.008 (ppm); 0.016±0.001 0.157±0.002 (ppm) 0.0001±0.0001 respectively; while II, these values 0.133±0.001 0.022±0.002 0.206±0.002 0.002±0.001 statistical difference between stations significantly higher (p<0.05). order metal load obtained was found to be Fe>Zn>Cu>Pb. Also, bioaccumulation viz. fish 0.374±0.011 (ppm), 0.105±0.02 0.094±0.04 and0.001±0.0001 on other hand, 0.539±0.013 0.156±0.04 0.121±0.023 0.0013±0.0001 respectively II. Even though experimental sites did not exceed acceptable limits recommended by agencies like FAO WHO, results showed an increasing trend accumulation, which definitely poses a serious threat survival aquatic organisms area.
