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.
在这项研究中，研究了土壤类型对商业形式的 C-nZVI 对赤子爱胜蚓组织浓度、细胞成分、繁殖结果以及土壤健康的影响。在三种土壤类型中，浓度为 3 g kg(-1)土壤的 C-nZVI 对赤子爱胜蚓的存活率没有影响。然而，观察到了不同的影响，例如 C-nZVI 导致组织铁浓度、脂质过氧化和 DNA 分子损伤的浓度依赖性增加。在 60 mg kg(-1)土壤暴露浓度下，C-nZVI 诱导赤子爱胜蚓产生氧化应激。组织铁浓度似乎与 DNA 损伤有关。氧化应激和 DNA 损伤可能解释了 nZVI 对赤子爱胜蚓的毒性机制。
