Profiling of toxic metals from fish (tor putitora), water and sediments with microbial and chemical water quality appraisals

The current study was focused on selected quality parameters of water, heavy metal contents of water, sediments and fish from Poonch river. Sediments, water and fish samples were gathered including six different sites in the period of April to June 2015. During the study period the mean value recorded for water quality parameters were pH 9.20, mv Oxidation Reduction Potential (ORP) 32.2, Dissolved (Oxygen) DO 6.95 mg/l, Electrical Conductivity (EC) 252.96mS/cm and 271.91 mg/cm, Total Dissolved Solids (TDS) 197.03, Salinity 0.77, Turbidity 3.02, Temperature 31.65 and Pressure 13.37. Mean values recorded for heavy metal absorption in river water, sediments and fish were below the maximum permissible levels. The aim of current study was to show that water is good for the existence of fish survival and its growth. So, this study exhibits that the part of Poonch River, Azad Jammu and Kashmir having water quality parameters and heavy metals were within the tolerable range and no harmful effects on the fish growth and reproduction.
