Seasonal variation of heavy metals in selected stations of Periyar river at Ernakulam district, Kerala, India
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 17, Issue 2
Abstract
Pollution status of heavy metals like nickel, zinc, arsenic and cadmium in water, sediment and the corresponding bioaccumulation in biomass of Anabas testudineus from different stations of periyar river at ernakulam district during three seasons of an year was analysed. Result showed that the concentration of heavy metals was higher in the water, sediment, biomass from station I and II than control station indicating the pollution status of the river system. The metal bioaccumulations in tissues may be related to the influx of metals from the industries on the banks of the River and their increased bioavailability to the fish there. Out of the four selected elements arsenic was not reported (always below detection level) from any of the samples. Heavy metals followed the order Zn > Ni > Cd in all the samples. Concentration was highest in the sediment samples following in the water sample and the least in the biomass with significant positive correlation between them. Seasonal variation followed a trend as premonsoon > postmonsoon > monsoon in majority of cases with exceptions. Liver > gills > muscle was the commonly found trend in bioaccumulation and varied with respect to metal, season and site.
