Increasing environmental pollution causes the search for new methods of purification. Currently, the remediation potential of nanoparticles is increasingly being studied. Unfortunately, there is still a lack of data on the impact of these compounds on living organisms, including plants. This study was designed to test the effects of nanoFER 25 and nanoFER 25S iron on Lolium westerwoldicum Breakw. After cultivation of plants in a soil contaminated with nanoparticles, the biometric parameters, content of polyphenols, flavonoids, chlorophyll changes, carotenoids, anthocyanins, superoxide dismutase, catalase and pyrogallol peroxidase were studied. The conducted experiment showed that nano zero-valent iron (nZVI) is slightly taken from the soil to the plants. The iron passes to the root but there is no further transport up the plant. The content of polyphenols and flavonoids in aboveground parts of plants decreases with a simultaneous increase in roots compared to the control sample. The chlorophyll content in the leaves is strongly related to the concentration of the contaminant. Similarly, the enzyme activity of the antioxidant system in the whole plant is strongly related to the concentration of the pollutant. The amount of vegetable pigments in the leaves increases for low concentrations of contamination and then decreases at higher levels of contamination. The study has shown that both types of nanoFER are not indifferent to the plants’ growth.

不同类型的nZVI对黑麦草的影响比较

日益严重的环境污染导致人们寻求新的净化方法。当前,越来越多地研究纳米颗粒的修复潜力。不幸的是,仍然缺乏有关这些化合物对包括植物在内的活生物体的影响的数据。这项研究旨在测试nanoFER 25和nanoFER 25S铁对黑麦草的影响早餐 在被纳米颗粒污染的土壤中种植植物后,研究了生物测定参数,多酚,类黄酮,叶绿素变化,类胡萝卜素,花色苷,超氧化物歧化酶,过氧化氢酶和连苯三酚过氧化物酶的含量。进行的实验表明,纳米零价铁(nZVI)从土壤中略带到植物中。铁传递到根部,但没有进一步向上运输的植物。与对照样品相比,植物地上部分中多酚和类黄酮的含量随着根部的同时增加而降低。叶片中的叶绿素含量与污染物的浓度密切相关。同样,整个植物中抗氧化剂系统的酶活性与污染物的浓度密切相关。叶片中植物色素的含量随着污染物浓度的降低而增加,然后在污染物含量较高时降低。研究表明,两种类型的nanoFER对植物的生长都没有影响。
