Abstract:
Metal pollution from multifarious sources like effluents from industries, agricultural
runoff and untreated sewage system has adverse effects on aquatic ecosystem. Metallopesticides,
including insecticides, fungicides, and herbicides are also known to contain
various metals that can increase metal accumulation. The presence of metal pollutant in
fresh water is known to disturb the delicate balance of the aquatic systems. Fish are often
at the top of the aquatic food chain and may concentrate large amounts of some metals
from the water. The study correlated the level of metal ions (Fe, Cu, Zn, Mn) in tissues
and in water in a time dependent as well as dose dependent manner in both the species of
teleost (O.mossambicus and L.rohita). Further Bioconcentration factor added metal based
affinity towards tissue. Hence, the study gears up and proves that among both the fishes
tested on exposure to micronutrient mixture, O.mossambicus was found to be more sturdy
i.e it was able to with stand more metal load compared to L.rohita in a time dependent
manner.
