Summary: This study found that leachate leakage enhances microbial diversity and transfers specific bacteria from landfills to groundwater, with organic matter being the key driving factor for microbial community evolution. Leachate pollution changes the assembly mechanism of microbial communities, reducing their efficiency and stability in groundwater. Microbial indicators are more sensitive to leachate leakage and can accurately identify landfills where leachate leakage occurs and other extraneous pollutants.

Summary: Most pharmaceuticals are stored in synthetic polymer bottles made of polyethylene, which can lead to toxicological impact on Donax faba. The leachate from the pharmaceutical container contained various organics and inorganics, with concentrations of heavy metals exceeding the standard reference value for drinking water. The leachate treatment resulted in increased protein concentration, elevated levels of reactive oxygen species (ROS) and malondialdehyde (MDA), and decreased activity of superoxide dismutase (SOD) and catalase (CAT). Moreover, the PET pharmaceutical containers could potentially release additives, causing oxidative and metabolic damages to higher organisms including humans.

Summary: The annual growth of water pollution, especially heavy metals like Pb2+ ions, is a crucial global concern due to its impact on human health. This study aims to evaluate the effectiveness of two new nano-adsorbents (Fe3O4@ZIF-8 and Fe3O4@SiO2@ZIF-8) in removing Pb2+ ions from water. Results showed that both nano-adsorbents had high removal efficiency, with Fe3O4@SiO2@ZIF-8 nanoparticles performing better due to their higher porosity and surface area ratio. Therefore, Fe3O4@SiO2@ZIF-8 can be considered a cost-effective and ideal nanosorbent for heavy metal removal from water.

Summary: This paper reviews the research progress of organophosphate esters (OPEs) in soil through bibliometric analysis, providing a comprehensive understanding of their pollution status, potential sources, and environmental behaviors. OPEs are widely distributed in soil at concentrations ranging from several to tens of thousands of ng/g dw. Waste processing areas serve as important point sources of OPE pollution in soil. The transfer process of OPEs in soil is influenced by emission source intensity, physicochemical properties of compounds, and soil properties. Microbial degradation, particularly by Brevibacillus brevis, Sphingomonas, Sphingopyxis, Rhodococcus, and other microorganisms, holds potential for the remediation of OPE-contaminated soil. This review clarifies the pollution status of OPEs in soil and provides insights for future research.

Summary: Rare earth elements (REEs), considered as emerging pollutants, have been increasingly released into the environment due to their extensive use in industries, agriculture, and high-tech devices. However, limited research has been conducted on REEs in urban soils. The objective of this study was to investigate the potential sources and risks of REEs in the urban environment. The study analyzed the concentration and distribution of REEs in urban park soils and used microgeochemical and random forest methods to determine the pollution sources of REEs. The results showed that the high concentrations of REEs were mainly found in the western part of Beijing near an industrial area, confirming the anthropogenic pollution sources from industry and traffic. Risk assessment indicated that the daily intake of REEs for both children and adults was below the reference threshold, suggesting negligible health risks.

Summary: Organophosphate esters (OPEs) are a new type of emerging contaminant in soil, attracting increasing attention due to their biological toxicity and potential threat to human health. This study investigated the pollution characteristics of two typical OPEs, tri-OPEs and di-OPEs, in soils of 104 urban parks in Beijing. The results indicate that consumer materials, traffic emissions, and reclaimed water irrigation may be critical sources of tri-OPEs, while di-OPEs mainly come from the degradation of parent compounds and industrial applications. Machine learning models were used to identify influencing factors and predict future changes in OPEs concentrations.
