Abstract
Eco-toxicity is an important consideration in understanding the potential environmental impacts of the release of nanomaterials into the environment. In this study, the potential genotoxicity of nanosized magnetic iron-based oxide particles used in the treatment of contaminated effluents by chemical catalysis processes such as Fenton reaction or photocatalysis was investigated using a simple method for the quantitative evaluation of DNA degradation. The selected nanoparticles were magnetite (Fe3O4), silica, citrate, poly (acrylic acid) and polyethylenimine coated magnetite (Fe3O4@SiO2, Fe3O4@Citratete, Fe3O4@PAA, Fe3O4@PEI) and two different magnetite nanocomposites with TiO2 and ZnO. The obtained results highlight the need for caution during the use and disposal of these manufactured nanomaterials, as DNA oxidation effects may be observed at very low concentrations.
