Abstract
In this study, the influence of soil types on the effect of the commercial form of C-nZVI on tissue concentrations, cellular component, reproduction outcome in Eisenia fetida, and the soil health was investigated. C-nZVI at concentration level of 3 g kg(-1) soil showed no effect on the survival of E. fetida in the three soil types. However, varying effects such as concentration-dependent increase in tissue iron concentration, lipid peroxidation, and damage to DNA molecules by C-nZVI were observed. C-nZVI at an exposure concentration of 60 mg kg(-1) soil induced oxidative stress in E. fetida. Tissue Fe concentration appeared correlated to the DNA damage. Oxidative stress and DNA damage may explain the toxicity mechanisms of nZVI to E. fetida. Graphical Abstract Reactive oxygen species induced by nZVI.Entities:
