Heavy Metal Pollution Induced Histopathological Changes in Anabas testudineus collected from Periyar River at Ernakulam district and the Recovery Responses in Pollution free water.
Journal Title: IOSR Journal of Pharmacy (IOSRPHR) - Year 2018, Vol 8, Issue 1
Abstract
Heavy metal (lead, nickel, zinc, arsenic and cadmium) pollution status in water, sediment and the corresponding bioaccumulation in biomass of Anabas testudineus from two different stations of Periyarriver at Ernakulam district (Station I- Eloor Industrial area, Station II- Irumbanam, Ernakulam) of two year period analysis showed that the bioaccumulation rate depends on pollution status in the environment. The histopathological changes in liver, gills and muscle varied based on the pollution load. The recovery responses were studied in fishes kept in aquaria maintained at controlled laboratory conditions for 30 days and from the results it was apparent that the pollution induces stress in fishes that has been reflected in the histological characteristics of vital organs. However by keeping them in pollution free waters positively influenced towards recovery from stress.
