Synergism of Heavy Metals on the Respiration of Oreochromis mossambicus

This study highlights the impact of heavy metals from electroplating industrial waste water on the respiration of the fish - Oreochromis mossambicus. Bioassays were conducted separately with chromium, nickel and mixed electroplating effluent on the fish. Results revealed quantum decrease in oxygen consumption levels in fish exposed to the highest concentrations of electroplating industrial effluent when compared to those exposed to chromium or nickel. The Two way ANOVA analysis exhibit significant influence of heavy metals in electroplating effluent on the respiration of fish. Synergism of heavy metals in electroplating effluent is projected in this work.
