The release of nanoparticles and biodegradable chelating agents into the environment may cause toxicological and ecotoxicological effects. The aim of this study is to determine the ecotoxic effects of zinc oxide (ZnO) nanoparticles and ethylenediamine disuccinic acid (EDDS) on most cultured four plants. The durum wheat, bread wheat, barley, and rye are exposed to 5 mL 10 mg L⁻¹ ZnO nanoparticles and 10 mg L⁻¹ EDDS in the seed germination stage. Results show that these different plant species have different responses to ZnO nanoparticles and EDDS. The germination percentage of bread wheat and rye decreases in the application of ZnO nanoparticles while the germination of durum wheat and barley increases as much as in radicle elongation and seedling vigor. While ZnO treatment causes a decrease in bread wheat and rye germinated rat in the range of 33–14.3%, respectively, there is no change in germination rate of these plants at EDDS treatment. In addition, EDDS treatment positively affects barley germination rate. In conclusion, it is clear that ZnO nanoparticles have more toxic effects on bread wheat and rye than EDDS, while barley is positively affected by ZnO nanoparticles and EDDS.

ZnO 纳米颗粒和乙二胺-N,N'-二琥珀酸对四种不同植物种子萌发的影响。


纳米粒子和可生物降解的螯合剂释放到环境中可能会引起毒理学和生态毒理学效应。本研究的目的是确定氧化锌 (ZnO) 纳米粒子和乙二胺二琥珀酸 (EDDS) 对大多数培养的四种植物的生态毒性影响。在种子萌发阶段，将硬粒小麦、面包小麦、大麦和黑麦暴露于 5 mL 10 mg L ^-1 ZnO 纳米粒子和 10 mg L ^-1 EDDS。结果表明，这些不同的植物物种对 ZnO 纳米粒子和 EDDS 有不同的反应。施用纳米氧化锌后，面包小麦和黑麦的发芽率降低，而硬粒小麦和大麦的发芽率增加，胚根伸长和幼苗活力增加。虽然 ZnO 处理导致面包小麦和黑麦大鼠的发芽率分别下降 33-14.3%，但 EDDS 处理时这些植物的发芽率没有变化。此外，EDDS 处理对大麦发芽率有积极影响。总之，很明显，ZnO 纳米颗粒对面包小麦和黑麦的毒性作用比 EDDS 更大，而大麦则受到 ZnO 纳米颗粒和 EDDS 的积极影响。
