Concentration of heavy metals in the water and fish tissues of the river ravi, Pakistan
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2015, Vol 6, Issue 2
Abstract
The River Ravi has subject to severe disturbances due to contaminants discharge of untreated industrial wastes and domestic sewage. This study was planned to assess the status of heavy metals Copper (Cu), chromium (Cr), cadmium (Cd) and cobalt (Co) in water and indian major carp (Catla catla) collected from the sampling station, Baloki Headworks. The results showed significant differences among six fish organs viz. Gills, kidney, liver, skin, muscle and scales. Accumulation of Cu in all the six fish organs showed significant difference. Fish liver was the organ that accumulated significantly higher quantities of these metals followed by that of kidney and scales. The magnitude of heavy metals in both river stretch and tributary waters were Cu > Cr > Cd > Co while in the fish tissue the elements decreased in the order Cu > Cr >Co> Cd. The correlation coefficient between the metals toxicity of Catla catla body organs and water was positively significant. The result of this study indicated that the metals present in the river system were taken up by Catla catla through water, sediments and food, regardless of their biological needs, showed higher metal concentrations.
