Summary: A bioluminescent-enzyme-inhibition-based assay was used to predict the potential toxicity of different soil samples. The inhibitory effect of the soil samples on the enzyme system activity decreased with a decrease in humic organic matter content in the soils. This method can be used to detect pollutant mobility and the extent of soil contamination.

Summary: Residual antibiotics and heavy metals continuously released from soil, reflecting their intensive use and contamination of water and soil, pose a significant environmental problem. This study explored the effects of single and combined actions of copper and antibiotics on the soil microbial community. The results showed that the combined effects of antibiotics and heavy metals can inhibit or promote the function of soil microbial communities, and the Integrated Biological Responses version 2 (IBRv2) method proves to be an effective method to evaluate the impacts of contaminants on soil health.

Summary: Soil enzymes play a significant role in the storage of soil organic carbon (SOC) and nitrogen (TN), but their relationships in aggregates, particularly in sodic-alkali agricultural fields, have been understudied. This study found that soil enzymes were heterogeneously distributed in aggregates, and their activities were closely related to SOC and TN across different aggregate sizes. Moreover, the study revealed that enzyme activities were higher in the surface layer compared to the subsurface layer, indicating the importance of biophysical processes associated with enzymes in the SOC and TN sequestration within soil aggregates.

Summary: Molecular oxygen is a sustainable oxidation reagent with strong oxidizing properties and stability, ultimately forming water as the reaction product. The activation of O-2 can occur through various pathways, with enzymes typically forming metal-oxygen coordination complexes to facilitate the process. The formylglycine generating enzyme (FGE) demonstrates a unique strategy for activating O-2, involving binding of O-2 near, but not coordinated to, its catalytic copper atom.

Summary: This study investigated the influences of polyethylene (PE) and phenanthrene (PHE) on soil ecosystems through a soil microcosm experiment. Results showed that the addition of PE and PHE affected soil chemical properties, enzymatic activities, and bacterial community diversity/composition. The significantly positive effect of PE on the nitrogen cycle and metabolic function led to notable changes in soil organic matter/nitrogen content and urease/FDAse activities.

Summary: Grasslands are important biomes on Earth, and this study assessed the impact of grazing on soil structure and quality. It found that heavy grazing reduces soil nutrient content and enzyme activities, as well as decreases water stability of soil aggregates. Therefore, heavy grazing should be avoided in grasslands of this type, and long-term monitoring of soil structure is necessary.

Summary: Understanding the vertical distribution and driving mechanisms of soil carbon, nitrogen, and phosphorus contents and enzyme activities along elevation gradients is important for the sustainable management of forest ecosystems. This study investigated samples from different altitudes in natural secondary Quercus spp. forests and found that the soil nutrient content was low, with higher values at higher altitudes. The stoichiometric attributes of the soil ecosystem fluctuated with altitude, and soil enzyme activities increased with altitude and were influenced by soil organic carbon, total phosphorus, and pH.

Summary: This study investigated the contamination characteristic of lithium in soil, and found that soil properties and enzyme activities were affected. The content of ammonium nitrogen, total nitrogen, and exchangeable potassium increased significantly, while electric conductivity and available phosphorus content increased as well. Soil pH and cation exchange capacity slightly changed, and nitrate nitrogen and sulfate content significantly decreased under higher lithium stress. The activities of some enzymes were promoted or inhibited by different levels of lithium treatment.

Summary: This study found that exposure to sublethal concentrations of cyantraniliprole led to reduced survival rate and hatchability of the small brown planthopper (SBPH). It also prolonged the nymphal duration and shortened the adult preoviposition period. The increase in detoxification enzyme activity may contribute to the development of insecticide resistance. This research provides valuable insights for managing resistant SBPH populations.

Summary: The study showed that continuous use of TFM can increase resistance of SBPH to TFM, but the resistance level can gradually decrease after stopping use. The resistant strains did not show cross-resistance to other neonicotinoid insecticides, but the increased activity of P450 enzyme may be due to the overexpression of P450 genes.

Summary: This study evaluated the chronic toxicity of fluopicolide to earthworms. The results showed that fluopicolide could cause oxidative stress and DNA damage in earthworms. As the dose and exposure time increased, the levels of reactive oxygen species increased, while the activities of antioxidant enzymes showed an increasing trend followed by a decreasing trend. The activity of glutathione S-transferase and the malondialdehyde content increased in a dose-dependent manner.
