Zno Nanoparticles: Characterization And Acute Lethal Studies In Eudrilus Eugeniae

Engineered nanoparticles (NPs) are increasingly being used in a range of consumer products and entered into the environment. NP ZnO is one of the most widely used and potentially toxic NPs in soil organisms. The purpose of this study is to identify the particle size of the synthesized ZnO NPs by FTIR and UV-Vis spectroscopic which helps to investigate their effect on surface interaction with biological organisms. The synthesized ZnO NPs size is found as 47nm. Eudrilus eugeniae earthworm species is used for identify the median lethal concentration of ZnO NPs. The LC50 for ZnO NPs is observed between 1.80 to 2.00 gm/kg. Exposure of ZnO NPs to Eudrilus eugeniae cause toxicity while increased NPs concentration increases the impact.
