The main focus of the study is to estimate the pollution level in University of Gujrat from Pakistan. For this purpose physical and chemical analysis of different water sample was performed. Different parameters like pH, TDS, electrical conductivity, bacterial growth, hardness, chlorides, BOD and COD was estimated. The results show that all the samples have high bacterial growth and four samples contain high electrical conductivity than standard value. PM, flue gases, ambient air and noise level was estimated. Air analysis gives a very alarming result due to high NOx level in the smoke of generators. All these were performed in order to warn the management about the environment of university of Gujrat so that steps should be taken to make the atmosphere healthy and safe.

This study aims to investigate the uptake of Zinc, Copper and Chromium in the muscles of Cyprinus carpio from Akram Shaheed Bridge and Rasul Barrage at river Jhelum in Punjab province, Pakistan in 2010. The Cyprinus carpio is one of the most edible fishes in Punjab. So it is necessary to determine the concentration of heavy metals in muscles as these can cause public health risks. Some heavy metals are biologically important as trace elements but many of them have the biotoxic effects in human biochemistry. So, it is essential to know about their sources, concentrations, their modes of deposition to pollute the environment, leaching processes, conversions and oxidation states which make them harmful and also how these become biotoxic, because when ingested the metals combine with biomolecules as proteins and enzymes to form compounds which are biotoxically stable. The domestic, industrial wastes and mining are the main sources for the heavy metals accumulation. So, this book will help you to know about the Cyprinus carpio and the health risks to fish as well as to man if he takes the fish contaminated with heavy metals.
