Abstract

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) 252.96µS/cm and 271.91 µg/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.

摘要

当前的研究聚焦于蓬奇河的特定水质参数、水中重金属含量、沉积物及鱼类中的重金属含量。在2015年4月至6月期间采集了沉积物、水和鱼类样本,包括六个不同地点。在研究期间,记录的水质参数平均值为pH值9.20、氧化还原电位(ORP)32.2毫伏、溶解氧(DO)6.95毫克/升、电导率(EC)252.96微西门子/厘米、总溶解固体(TDS)197.03、盐度0.77、浊度3.02、温度31.65以及压力13.37。记录的河水中、沉积物和鱼类中重金属吸收的平均值低于最大允许水平。当前研究的目的是表明该水域有利于鱼类生存和生长。因此,本研究表明,查谟和克什米尔自由邦蓬奇河的这一部分,其水质参数和重金属含量在可容忍范围内,对鱼类生长和繁殖无有害影响。
