Nowadays, nanotechnology is one of the most dynamically developing and most promising technologies. However, the safety issues of using metal nanoparticles, their environmental impact on soil and plants are poorly understood. These studies are especially important in terms of copper-based nanomaterials because they are widely used in agriculture. Concerning that, it is important to study the mechanism behind the mode of CuO nanoparticles action at the ultrastructural intracellular level. It is established that the contamination with CuO has had a negative influence on the development of spring barley. A greater toxic effect has been exerted by the introduction of CuO nanoparticles as compared to the macrodispersed form. A comparative analysis of the toxic effects of copper oxides and nano-oxides on plants has shown changes in the tissue and intracellular levels in the barley roots. However, qualitative changes in plant leaves have not practically been observed. In general, conclusions can be made that copper oxide in nano-dispersed form penetrates better from the soil into the plant and can accumulate in large quantities in it.

不同分散度的CuO对春ley细胞结构和超微结构的毒性作用。

如今,纳米技术是发展最快,最有前途的技术之一。但是,人们对使用金属纳米颗粒的安全性问题,其对土壤和植物的环境影响知之甚少。这些研究在铜基纳米材料方面尤其重要,因为它们已广泛用于农业。关于这一点,重要的是研究在超微结构胞内水平上CuO纳米颗粒作用模式背后的机理。可以确定的是,CuO的污染对春季大麦的发育产生了负面影响。与大分散形式相比,通过引入CuO纳米颗粒已经发挥了更大的毒性作用。氧化铜和纳米氧化物对植物的毒性作用的比较分析表明,大麦根部组织和细胞内水平发生了变化。但是,实际上没有观察到植物叶片的质变。通常,可以得出结论,纳米分散形式的氧化铜可以更好地从土壤渗透到植物中,并可以在其中大量积累。
