“…Previous studies have also shown the least effect of Ni NPs among other investigated substances [ 15 , 46 ] and a strong toxic effect of CuNPs on the biological parameters of soils [ 22 , 47 , 48 , 49 ]. In addition, our studies have confirmed the hypothesis that the higher the dose of the pollutant, the stronger the inhibition of biological indicators, which is agreement with previously reported results [ 19 , 46 , 50 , 51 ].…”

An increase in the penetration of metal-based nanoparticles (NPs) into the environment requires an assessment of their ecotoxicity as they impair the critical activity of plants, animals, bacteria, and enzymes. Therefore, the study aimed to observe the effects of metal-based NPs, including copper (Cu), nickel (Ni), and zinc (Zn), on the Cambisols, which cover a significant part of the earth's soil and play an important role in the biosphere. Metal-based NPs were introduced into the soil at concentrations of 100, 1,000, and 10,000 mg/kg. The biological properties of the soil are being investigated as the most sensitive to external contamination. The highest ecotoxicity of the studied pollutants introduced into the soil at the same concentrations was shown by Cu (up to 34%) and Zn (up to 30%) NPs, while Ni NPs showed less (up to 22%). Microbiological (total number of bacteria, Azotobacter sp. abundance) and phytotoxic properties (radish seed germination and length of roots) of Cambisols were more sensitive (22–53%) to pollution by NPs of Cu, Zn, and Ni, while enzymatic activity (catalase and dehydrogenases) showed less sensitivity (14–32%). The present results could be useful for biomonitoring the state of contaminated soils, especially by NPs.

“…Since some are sensitive, and other indicators are informative, it is advisable to use the integral indicator of the biological state (IIBS). It was recently found that the biological condition of Haplic Chernozem was negatively influenced by the AgNPs, nanoparticles of nickel, iron, cobalt, zinc [32,33,43].…”

However, the ecological effects of soil pollution with AgNPs were studied poorly compared to the nanosized of other metal-based NPs, such as iron, nickel, zinc, and copper [32][33][34]. Therefore, it seems relevant to identify the influence of AgNPs on the biological properties of the Haplic Chernozem.…”

In recent years, silver nanoparticles (AgNPs) are increasingly used in various industries due to their antibacterial properties, which lead to an increase in pollution of the environment and soil ecosystems. However, the ecological effects of soil pollution by AgNPs were poorly studied than that with AgNPs of other metal-based NPs. The aim of this study is to assess the influence of AgNPs on the biological properties of Haplic Chernozem. Silver was introduced into the soil in the form of AgNPs with a concentration of 0.5; 1; 5; 10; 50, and 100 mg/kg in laboratory conditions. The influence of AgNPs on the biological properties of Haplic Chernozem was assessed 30 days after contamination. The degree of reduction in biological properties depends on the AgNPs concentration in the soil. This study showed that the sensitivity to contamination by AgNPs in the total number of bacteria and enzymatic activity was more than that in the abundance of bacteria of the genus Azotobacter. The integrated index of biological state (IIBS) of Haplic Chernozem was decreased by contamination with AgNPs. Silver nanoparticles in the concentration of 10 mg/kg caused a decrease in the indicator by 13% relative to the control. It also decreased IIBS by doses of 50 and 100 mg/kg by 22 and 27% relative to the control. All used biological indicators could be used for biomonitoring, biodiagnosis, bioindication, and regulation of ecological condition of soil contamination by AgNPs.

“…The advent of nanotechnologies in the recent decades has induced intensive development of many areas of human activities, first and foremost, medicine and analytical chemistry, since this made it possible to design new ways for drug delivery and diagnostic methods [27]. Ever increasing rates of production and use of nanoparticles in these technologies necessitate regarding them as a new class of toxicants, which can either directly or indirectly injure both the human health and the environment [2,4,12]. Diamond nanoparticles or nanodiamonds (NDs) occupy a special position among the nanomaterials with their increasing use [20].…”

An increasing rate of the use of nanoparticles necessitates regarding them as a new class of toxicants. Nanodiamonds hold a special position because of their use in consumer goods, such as fuels and lubricants, which increases the risk of soil pollution with these nanoparticles. The goal of this study was to assess the effects of water-soluble soil components on the electrokinetic potential (ζ-potential) and size of detonation nanodiamonds. Water extracts from 15 zonal soil samples were studied. Addition of nanodiamonds to soil water extracts caused an increase in the weighted average hydrodynamic diameter of nanodiamonds from 24 to 69-683 nm and a drop in absolute ζ-potential from -22 to -(11.2-19.50) mV; an increase in the absolute ζ-potential to -34.5 mV was observed in one case. The highest increase in the size of nanodiamonds was detected in the extracts with high pH values and high Ca/(Fe + Al) ratio. The observed inverse correlation of the ζ-potential of nanodiamonds with the extinction coefficient of the dissolved soil organic matter and the iron content in water extracts suggested that the stability of nanodiamonds could increase in soil solutions in the presence of low molecular weight components of dissolved soil organic matter and at high iron concentrations. Generally, the obtained results allow us to assume that coagulation of nanodiamonds and a decrease in their mobility in soil are due to their interaction with water-soluble soil components. Water extracts from solonetzes are an exception, because the mobility of nanodiamonds in them may increase.
