Abstract

Humic acid can vary the toxicity of biotoxins at different environments when it is bond to them. Therefore, the interaction between nanoparticles and humic acid is specially considered in the view of environmental point. The objectives of this study were the investigation of ZnO nanoparticle toxicity on rapeseed at germination stage, and the reduction of the nanoparticle toxicity by humic acid in laboratory condition. The experiment was conducted with nine concentrations of 0, 250, 500, 750, 1000, 1250, 1500, 1750, 2000 mg / L zinc oxide nanoparticle and two concentrations of 0, 100 mg / L humic acid, as factorial in a completely randomized design with three replications. The results showed that increasing of the ZnO nanoparticle concentration caused increasing the activity of superoxide dismutase, ascorbate peroxidase, catalase and peroxidase enzymes, while the protein content showed a reduction trend. Humic acid application decreased the toxicity effects of ZnO nanoparticle. Increasing the concentration of ZnO nanoparticle caused reduction in Germination indices (such as final germination percentage, germination energy, germination rate and seed vigor index). However, application of humic acid resulted in improving the Germination indices, antioxidants activity in the plant and a reduction of toxicity by protecting the plant against the ZnO nanoparticle.
