Summary

This editorial introduces a research collection on microbial responses to emerging contaminants — including microplastics, antibiotics, and heavy metals — in soil and sediment ecosystems. Researchers highlight the importance of understanding how these contaminants interact to alter microbial community diversity, function, and ecological balance in terrestrial and aquatic environments.

network. In addition to microplastics, antibiotics, and heavy metals, have also attracted wide attention for their environmental toxic effects and pollution mechanisms on soil in recent years, especially the comprehensive toxic effects of these two substances on soil microorganisms (Wang et al., 2021). As the backbone of various environmental ecosystems, microbial communities play a key role in maintaining ecological balance and function. There is therefore a need to understand how these contaminants alter microbial diversity, function, and the overall health of soil and sediment environments. Ammonia-oxidizing archaea and bacteria and their related soil nitrification functions play a key role in soil nitrogen turnover. Therefore, it is widely used to assess the ecological risks of soil pollution (Chen et al., 2023). Hou et al. found that the impacts of sulfadiazine (SDZ) and copper (Cu) on ammonia-oxidizing archaea and ammonia-oxidizing bacteria communities depended on soil types, and the specific phylotype corresponded to the PNR variation under the stress of SDZ and Cu.Microorganisms play a key role in the soil biogeochemical cycle, and in addition to the effects of emerging contaminants released into the environment, changes in the microbial community structure in the soil also interact with the characteristics of the soil environment (Du et al., 2022). Liu et al. found that soil enzyme activity and potential nitrification rate largely depended on the composition and richness of the bacterial community rather than the diversity, which were greatly changed by the availability of soil nitrogen and phosphorus. According to Symochko et al.cellulose-destroying microorganisms are chemical rot bacteria with high organic matter content in soil, and intensive agricultural practices in Ukrainian soil have greatly changed the content and composition of organic matter, resulting in a decrease in humus and soil organic matter reserves.Soil is responsible for many productive activities, such as mining and construction, but these activities affect the community structure and function of soil microorganisms to varying degrees.Coal mining is an important production activity, and it is also the most obvious example of man-made degradation of the ecological environment (Liu et al., 2016). It is very important to choose the appropriate vegetation restoration method to maintain the stability of the artificial restoration soil ecosystem in mining areas (Li et al., 2018). Liu et al. found that the bacterial community structure and diversity were closely related to the age and type of forest restoration, and soil total carbon, total nitrogen, NH4 + -N, total phosphorus, and pH were the main environmental factors to the bacterial community structure of coniferous forest and broadleaf forest, and this study was crucial to promote the use of microorganisms to reveal the effect of environmental restoration.Promoting energy transformation is crucial to the realization of China's dual-carbon goal, and the use of clean energy such as solar energy and wind energy has helped this transformation to a certain extent. However, the use of these two kinds of energy cannot be separated from the construction of solar panels and windmills. Now, many scholars are studying the impact of solar panel construction on the environment. At present, there is a view that the installation of solar power plants is considered a "win-win" strategy because it can reduce carbon emissions and prevent desertification in arid areas at the same time (Liu et al., 2020). Liu et al. assessed the potential environmental benefits and risks of solar photovoltaic power plants from the perspective of soil microbial ecosystems and found that solar photovoltaic devices affected plant aboveground biomass to change the total nitrogen content. In addition to the direct impact, changes in plant aboveground biomass also indirectly drove the diversity of fungal communities by changing the total nitrogen content in the soil. Reducing the proportion of functional microbiota, the temperature drop caused by solar panel shading also directly inhibited the growth and activity of soil microorganisms (Yue et al., 2021).In general, microorganisms play an important role in soil biogeochemical cycles. This research topic aims to explore and continue to pay attention to the impact that emerging contaminants (such as microplastics and heavy metals) on microorganisms and ecosystems in soil and sediment ecosystems. And stimulate the readership's interest in the various effects of emerging contaminants in soil ecosystems.
