Summary: The study demonstrates that aging of metal-oxide nanoparticles in soil significantly enhances metal uptake by plants, leading to impacts on biomass accumulation and chlorophyll formation in cucumbers. This highlights the importance of careful consideration when using aged metal-oxide NPs for agricultural purposes, especially with essential and non-essential metals interacting with cucumber plants.

Summary: The study found that there were no significant differences in PBDE concentrations in air, rhizosphere soil, and crop samples collected from e-waste dismantling areas. PBDEs were selectively enriched in different tissues, suggesting a complex transport and distribution mechanism in the environment.

Summary: When multiple metals are present at levels slightly below their investigation levels, they can still cause phytotoxicity due to synergy. Three successive trials showed that a mixture of Cd, Cu, and Zn, even at lower concentrations than the Australian ecological investigation level, caused a reduction in plant growth.

Summary: Metal uptake and distribution in crops vary depending on the metal and crop type. This study compared the uptake and distribution of Hg, As, Zn, Pb, Cd, and Cu in three crops (leafy, fruit, and grain) grown near a copper mining field in Yunnan, China. Leafy crops had a higher propensity to accumulate Hg, As, and Zn, while grain crops had a lower accumulation of Cd and Cu. None of the crops accumulated Pb in their edible tissues. There was no correlation between DTPA-extracted metal concentrations in soil and metal concentrations in crop tissues.

Summary: This study quantified the uptake and size distribution of CeO2, La2O3, Fe3O4, and MnFe2O4 nanoparticles (NPs) in five different plants. The results showed that all four types of NPs were taken up by the plants, and their size distribution varied in different plant parts. Amaranth had the highest particle concentration, while kidney beans had the highest concentration of Fe (MnFe2O4)-based NPs. In addition, in vitro digestion experiments revealed that these NPs may be accessible to the human system.

Summary: This study investigates the accumulation of erythromycin (FRY) in soil and hydroponic vegetable cultivation systems. It finds that FRY can be absorbed by pakchoi and water spinach, but has limited translocation from roots to shoots in these vegetables. The accumulation level of FRY is similar between the two vegetables in soil systems, but pakchoi has a higher accumulation than water spinach in hydroponic systems. The intake of FRY through vegetable consumption is much lower than the maximum acceptable daily intake, indicating negligible risks.

Summary: The widespread use of metal-based nanoparticles has generated great interest in nano-biosafety. As these nanoparticles are released into the environment and eventually reach the soil, plants are at a higher risk of exposure and response. Arabidopsis, being a model plant, can provide valuable insights into the impact of environmental stress on plant growth and development, which can be applied to other plants as well. This study reviews the interactions between metal-based nanoparticles and Arabidopsis, focusing on internalization and phytotoxic effects, in order to understand how nanomaterials affect plant growth and development. The study also identifies unsolved problems in this field and suggests future research directions.

Summary: This paper is the first meta-analysis that examines the effects of microplastics on plant and soil health in the plant-soil system. The study finds that the composition of polymers in microplastics can impact plant morphology, antioxidant production and photosynthesis capacity. Different agricultural plants also show varying sensitivity to microplastics. Microplastic-impacted soils tend to be more porous and retain more water, but this does not improve soil stability or increase soil microbial diversity.

Summary: Arsenic and copper are common co-contaminants in soils, and their accumulation and distribution in As-hyperaccumulator Pteris vittata are influenced by their interactive effects. Increasing arsenic concentration reduces copper accumulation in fronds, while copper does not affect arsenic accumulation. P. vittata accumulates more copper than arsenic in roots, contributing to the low translocation of arsenic.

Summary: The study suggests that silver nanoparticles demonstrate the highest antimicrobial activity, especially those with a size of 97 nm. However, silver nanoparticles do not exhibit viral properties compared to copper and bimetallic nanoparticles, which have higher virus titres. Additionally, bimetallic nanoparticles combining silver and copper show no genotoxicity compared to pure metal nanoparticles.

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: The choice of workflow in wastewater surveillance has a significant impact on SARS-CoV-2 concentrations, while having minimal effects on HF183 and no effect on HAdV 40/41 concentrations. Certain components in the workflow can be interchangeable, but factors such as buffer type, chloroform, and homogenization speed can affect the recovery of viruses and bacteria.

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: Growing pressure from climate change and agricultural land use is destabilizing soil microbial community interactions. Little is known about microbial community resistance and adaptation to disturbances, hindering our understanding of recovery latency and implications for ecosystem functioning. This study found that anthropic disturbance and natural disturbance have different effects on the topology and stability of soil microbial networks.

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.
