Summary: The study showed that the presence of TiO2 and ZnO nanoparticles did not significantly affect the growth rate of earthworms and their superoxide dismutase activity during vermicomposting. However, higher concentrations of the nanoparticles promoted the humification of sludge and enhanced bacterial diversity. Furthermore, the study found that the presence of TiO2 and ZnO nanoparticle residuals modified the microbial community of sludge, hence promoting sludge humification during vermicomposting.

Summary: Pyrolysis combined with land application for dewatered municipal sludge disposal has advantages in solidifying heavy metals and utilizing resources. This study proposes and verifies the preparation of calcium-containing porous adsorbents from dewatered municipal sludge through pyrolysis. The results show that the adsorbent obtained from pyrolyzing at 900 degrees C has a high adsorption capacity for phosphorus and does not leach heavy metals. Additionally, the addition of this adsorbent promotes plant growth and economic estimates demonstrate its cost-effectiveness.

Summary: This study demonstrates a simple one-step pyrolysis method for synthesizing a catalytic sludge-based carbon (SBC) biochar containing Fe and Mn. The electrocatalytic degradation of triclosan (TCS) in water using an Fe/Mn-SBC cathode was evaluated. The catalyst generated at 500 degrees C exhibited a porous structure and high surface area, leading to improved conductivity and electron diffusion. By enhancing the catalytic performance of the biochar, the degradation of TCS was significantly improved. This study provides a simple and ecofriendly approach for the electrocatalytic degradation of organic pollutants.

Summary: NO2 emissions from wall-mounted gas stoves used for household heating have become a significant source of indoor pollution in Chinese urban areas. The high indoor concentration of NO2 poses potential health risks to residents. It is urgently necessary to establish relevant regulations and implement emission reduction technologies to reduce NO2 emissions from wall-mounted gas stoves.

Summary: This study investigates the relationship between dissolved organic matter (DOM) and Rare Earth Elements (REEs) in sediments from Yundang Lagoon, China. The results show four distinct fluorescent components, with protein-like substances being the most prevalent. Additionally, the total fluorescence intensity and LREE concentrations exhibit a synchronized increase from Outer to Inner to Songbai Lake core sediments. The findings demonstrate a strong correlation between DOM content and pollution levels.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Summary: In this study, inverse vulcanized polysulfides (IVP) were synthesized by reacting molten sulfur with 4-vinyl benzyl chloride, and then functionalized using N-methyl D-glucamine (NMDG). The functionalized IVP showed a high mercury adsorption capacity and a machine learning model was developed to predict the amount of mercury removed. Furthermore, the functionalized IVP can be regenerated and reused, providing a sustainable and cost-effective adsorbent.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
