“…In the current research, it was found that the activity of dehydrogenases is more sensitive to Ag pollution than that of activity catalase. The high sensitivity of activity of dehydrogenases to Ag was also confirmed by Yan et al [24]. Previous research has found impacts of AgNPs on enzyme activities, microbial biomass, microbial diversity, nitrification, and decomposition of organic matter of soil [19,20,22,60].…”

“…Our study is consistent with the hypothesis that the higher the concentration of AgNPs in the soil, the more pronounced the toxic effect on the biological parameters of soils (enzyme activity, the number of soil bacteria, phytotoxic indicators). Earlier dose-dependent inhibitory effect of AgNPs on the germination of rice seeds and their subsequent growth and development on the microbial and enzymatic activities of the soil was noted [24,64].…”

“…There are studies devoted to the ecotoxicological effect of AgNPs on the activity of soil of acid and alkaline phosphatase, β-glucosaminidase, β-glucosidase, arylsulfatase, urease, dehydrogenases, phenoloxidases, and arylamidase [23][24][25]61]. Arylamidase and phenoloxidase activity was inhibited by high doses of 100 mg/kg of AgNPs [62].…”

“…The effect of AgNPs on the activity of urease, β-glucosidase, alkaline phosphatase, and the composition of the microbial community in sandy loam soils, which differ in their properties from Haplic Chernozem [64]. The effect of AgNPs on the activity of enzymes in calcareous soils, which are similar to Haplic Chernozem, was investigated [24]. The effect of similar doses of AgNPs (0.01, 0.1, 0.5, 1, 5, 10, 20, 50 mg/kg) on the activity of soil urease and phosphatase was investigated [23].…”

“…It was found that the AgNPs were affected plants [14][15][16][17], soil microorganisms [18][19][20], and the activity of soil enzymes [21][22][23][24]. In addition, silver is known to accumulate in plants, mainly in root tissues [25].…”

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 effects of silver nanoparticles (Ag NPs) on the soil environment have attracted considerable research attention. Previous studies mainly focused on agent‐coated Ag NPs, which inevitably introduce additional disturbance of chemical agents to the intrinsic property of Ag NPs. We investigated the environmental effects induced by pure surfactant‐free Ag NPs (SF‐Ag NPs), including soil enzyme activities (urease, sucrase, phosphatase, and β‐glucosidase), bacterial community structure, and functional profile, over different exposure periods in the present study. The results indicated that these enzymes, especially urease and phosphatases, exhibit different responses to SF‐Ag NPs and are more susceptible to SF‐Ag NPs than other enzymes. Surfactant‐free Ag NPs can also induce a decrease in bacterial diversity and a change of bacterial community structure. The abundance of SF‐Ag NPs in Proteobacteria increased, but decreased in Acidobacteria after 14 days of exposure. Moreover, the abundance of genus Cupriavidus was significantly higher than those of the respective controls. By contrast, SF‐Ag NP exposure for 30 days could attenuate these negative effects. The phylogenetic investigation of communities by reconstruction of unobserved states (PICRUSt) prediction revealed that SF‐Ag NPs exert a negligible effect on bacterial function, thereby suggesting that functional redundancy is conduced to bacterial community tolerance to SF‐Ag NPs. These findings will help us further understand the environmental toxicity of Ag NPs. Environ Toxicol Chem 2023;42:1685–1695. © 2023 SETAC
