Effect of broad range doses of oral administration of Zinc Oxide Nanoparticles in freshwater fish Oreochromis mossambicus

Abstract

Due to high production and application, nanoproducts reaching aquatic environments have become unavoidable. Among aquatic species, fishes are more susceptible to waterborne contamination and are recognized as bioindicators for water quality monitoring. The present study is to evaluate the haematological and biochemical changes including enzymatic defence systems in freshwater tilapia (Oreochromis mossambicus), on exposure to Zinc Oxide (ZnO) nanoparticles (NP) orally in the range of 100, 200, 300, 400 and 500 ppm for 4 days. ZnO NP led to significant (P
