Summary: This study investigates the effects, uptake, bioaccumulation, localization, and possible transformations of two different forms of zero valent iron nanoparticles (nZVI) in a model plant, Arabidopsis thaliana. The results indicate that Arabidopsis plants do take up, transport, and accumulate nZVI in all parts of the plants, including the seeds. This will provide a better understanding of the behavior and transformations of nZVI once released into the environment, which is a critical issue from the point of view of food safety.

Summary: Coupling ZVI with plant biomass in the ecological floating bed (EFB) can enhance denitrification performance, as plant biomass promotes electron transfer of ZVI and improves Fe(II)-mediated denitrification. High-throughput sequencing analysis showed that IB-EFB enriched iron-related denitrifying bacteria more effectively than ICEFB, with high abundance of phototrophic Fe(II)-oxidizing bacteria Rhodopseudomonas (19.26%). This study indicates the potential for enhanced nitrogen removal in EFB by coupling ZVI with plant biomass.

Summary: Research has shown that nanoscale zero-valent iron (nZVI) used to remediate polluted aquifers can cause stress to bacteria. This study aimed to investigate the physiological and transcriptomic response of the bacterium Pseudomonas putida NCTC 10936 to nZVI and dissolved iron obtained from nZVI suspension. The results revealed that dissolved iron had a stronger physiological effect than nZVI, activating genes related to oxidative stress responses, antioxidant activity, and metabolism, while downregulating genes associated with sensing external stimuli. Despite the stress caused by dissolved iron, cell viability was not affected.

Summary: nZVI treatment resulted in decreased soil pH value, redox potential, and Fe (II) content. It also significantly decreased the relative abundance of certain microbial communities related to carbon and nitrogen cycles. Additionally, nZVI treatment led to reduced grain yield and decreased protein content and essential nutrient levels in a dose-dependent manner. The metabolomics results indicated that nZVI interfered with the expression of lysine and glutathione by regulating antioxidant and protein synthesis pathways in rice.

Summary: Zero valent iron (ZVI) has been shown to reduce antibiotic resistance genes (ARGs) in microbes by inhibiting horizontal transfer of ARGs and decreasing proliferation of resistant strains. However, a higher dosage of 20 g/L ZVI had negligible effects on ARGs reduction, possibly due to iron-catalyzed oxidative damage and reduced physiological activity.

Summary: In this study, an integrated system of Fe-0 and hydrogenotrophic microbes mediated by nitrate (NMB-Fe-0) was established to remediate Cd(II)-contaminated sediment. The results showed that the system successfully immobilized and enriched Cd(II)(aq) on iron surface through the promotion of iron corrosion and increased biomineral production. The Cd(II)(aq) removal rate in the NMB-Fe-0 system was much higher compared to the NM-Fe-0 system, and the leachability of Cd(II) decreased significantly while the residual fraction increased.

Summary: A strain of Cr(VI)-resistant bacterium, identified as Bacillus cereus ZY-2009, showed high tolerance to Cr(VI) and effectively removed Cr(VI) through enzyme-mediated bioreduction. Co-existing Fe3+ and Cu2+ enhanced Cr(VI) removal, while Cd2+ inhibited it. This strain has potential for bioremediation of Cr(VI)-containing wastewater with Fe3+ and Cu2+ as stimulators.

Summary: This study investigates the combined effects of soil amendments and indigenous microorganisms (IMOs) on the immobilization and accumulation of heavy metals (HMs) in coriander plants grown in acidic soils contaminated with HMs. The study demonstrates that the application of nano-hydroxyapatite (n-HAP), with or without IMOs, increases plant biomass and reduces Cd and Pb uptake in most cases. Furthermore, the combination of IMOs and n-HAP shows a synergistic effect in reducing the extractable Cd and Pb concentrations in slightly contaminated soil. Overall, the combination of IMOs and n-HAP is optimal for stabilizing and reducing HMs' uptake and promoting plant growth in contaminated soil.

Summary: Through a 10-month soil incubation experiment, we found that both nitrogen deposition and microplastics have significant effects on soil multifunctionality. Nitrogen deposition increased carbon cycling processes but inhibited nitrogen fixation, nitrification, and denitrification. Microplastics also stimulated these processes, especially in soils with nitrogen deposition.

Summary: The use of arbuscular mycorrhizal fungi (AMF) is important for enhancing phytoremediation of heavy metals, but their role under molybdenum (Mo) stress is unclear. This study investigated the effects of AMF inoculation on Mo uptake, transport, and physiological growth of maize plants under different Mo levels. The results showed that AMF inoculation increased biomass and induced different growth allocation strategies in response to Mo stress. It also enhanced the uptake of nutrients, improved photosynthetic leaf pigment content, and reduced Mo transport, indicating their potential for the bioremediation of Mo-polluted soil.

Summary: The effects of micro(nano)plastics (MNPs) on soil nutrient cycling, particularly carbon (C), nitrogen (N), and phosphorus (P), are reviewed. MNPs can alter soil nutrient cycling by affecting soil nutrient availability, enzyme activities, microbial communities, and ecological functions. The effects of MNPs depend on their characteristics, chemical additives, soil conditions, and biota. Multi-scale experiments using environmentally relevant MNPs are needed to further understand the impacts of MNPs on soil nutrients.

Summary: Microplastics (MPs) are widely distributed in agroecosystems and pose a potential threat to soil-plant systems. The effects of high-density polyethylene (HDPE), polystyrene (PS), and polylactic acid (PLA) on peanuts and soil N-fixing bacterial communities were explored. MPs did not have phytotoxic effects on plant biomass, and PS and PLA even increased plant height. All MPs changed soil nitrogen contents and the activities of urease and FDAse. PLA especially had pronounced effects on plant nitrogen content and soil N-fixing bacterial community structure. The findings suggest that biodegradable MPs may have more profound consequences for nitrogen biogeochemical cycling than traditional MPs.

Summary: The effect of different fermentation methods on heavy metal bioaccessibilities in wheat flour is uncertain. This study assessed the gastric and gastrointestinal heavy metal bioaccessibility in wheat flour products, and found that cadmium, zinc, and manganese bioaccessibility was higher in the gastric phase than in the gastrointestinal phase, while copper showed the opposite pattern. Lead bioaccessibility in the gastrointestinal phase was significantly greater than in the gastric phase for the QD sample, and only the control had higher bioaccessibility in the gastrointestinal phase than in the gastric phase for the NX sample. The over-fermented treatments showed higher bioaccessibilities of cadmium, copper, zinc, and manganese in the gastric phase compared to the control and normally fermented treatment. However, in the gastrointestinal phase, only the over-fermented dough with Na2CO3 showed higher manganese bioaccessibility compared to the control for the NX sample. The enhanced degradation of heavy metal-phytate following over-fermentation may contribute to the increased bioaccessibility of heavy metals.
