1. To Investigate The Effects Of Heavy Metals Toxicity On Vital Organs Of Rohu (Labeo Rohita)

by Ghina Islam | Prof. Dr. Muhammad Ashraf | Mr. Muhammad Hafeez-ur-rehman.

Material type: book Book; Format: print Publisher: 2013Dissertation note: At the time of collection of samples Temperature, Dissolved Oxygen, Total Dissolved Solids (TDS), Conductivity and pH were determined (YSI Digital meters) of selected sites for any possible relationship between water quality parameters, heavy metal concentrations and their effects on fish body. Fish from the selected water bodies was blotted dry and then weighed individually. After wet digestion of the sampled fish, the volume was prepared for the determination of heavy metals viz. chromium, copper, cadmium, lead, nickel and manganese. Samples for histological studies were collected on monthly basis. Slides were prepared. The results of this study provided valuable information on the metal contents in fish from different sampling stations. Fish from Balloki Headworks exhibited the highest tendency of accumulation of cadmium, lead and chromium in liver and intestine while it was the minimum in fish collected from controlled fish ponds from Ravi Campus Pattoki. Accumulation of these metals was, however, the minimum in fish muscle collected both from Fish ponds Pattoki and Balloki Headworks. The present situation can be considerably improved by taking effective measures such as better cleaning of waste water from the industrial enterprises and urban agglomeration as well as by installing new waste water treatment plants.
