Key process for reducing grains arsenic by applying sulfate varies with irrigation mode: Dual effects of microbe-mediated arsenic transformation and iron plaque
Environ Pollut. 2023 Sep 16:122569. doi: 10.1016/j.envpol.2023.122569. Online ahead of print.ABSTRACTSulfate affects the transformation of arsenic (As) in soil and its absorption by plant roots. However, the influence of sulfate and irrigation interactions on the mobility of As in the soil-rice system remains poorly understood. To address this gap, we conducted a pot experiment with varying sulfate levels and irrigation modes to examine their effects on rice As translocation, soil As forms, iron plaque formation, and microorganisms involved in As transformation. The addition of exogenous sulfate significantly reduced grain...

Rotenone nanoparticles based on mesoporous silica to improve the stability, translocation and insecticidal activity of rotenone
Environ Sci Pollut Res Int. 2023 Sep 19. doi: 10.1007/s11356-023-29842-6. Online ahead of print.ABSTRACTNanotechnology has been widely applied for pesticide carriers, which is an important way to improve the utilization, stability, and sustained release of pesticides. Mesoporous silica nanoparticles (MSNs) are a nanomaterial with adjustable particle and pore sizes, with a high specific surface area and good biocompatibility. Rotenone is a non-systemic botanical insecticide that is easily degraded in the environment. We used a modified soft-template method to prepare MSNs, in which rotenone was loaded using the solvent evap...

Se Ameliorates Cd Toxicity in Oilseed rape (Brassica napus L.) Seedlings by Inhibiting Cd Transporter Genes and Maintaining root Plasma Membrane Integrity
Bull Environ Contam Toxicol. 2023 Sep 16;111(3):42. doi: 10.1007/s00128-023-03804-7.ABSTRACTSe (Selenium) has been reported to be an important protective agent to decreases Cd (Cadmium) induced toxic in plants. However, it remains unclear how Se mitigates the uptake of Cd and increased the resistance to Cd toxicity. Hydroponic experiments were arranged to investigate the changes of physiological properties, root cell membrane integrity and Cd-related transporter genes in rape seedlings. Comparison of the biomass between the addition of Se and the absence of Se under Cd exposure showed that the Cd-induced growth inhibition ...

Congener-specific uptake and accumulation of bisphenols in edible plants: Binding to prediction of bioaccumulation by attention mechanism multi-layer perceptron machine learning model
In this study, the uptake, translocation, and accumulation of five bisphenols (BPs) in carrot and lettuce plants were investigated through hydroponic culture (duration of 168 h) and soil culture (duration of 42 days) systems. The results suggested a higher bioconcentration factor (BCF) of bisphenol AF (BPAF) in plants than that of the other four BPs. A positive correlation was found between the log BCF and the log Kow of BPs (R2carrot = 0.991, R2lettuce = 0.784, P < 0.05), while the log (translocation factor) exhibited a negative correlation with the log Kow (R2carrot = 0.882, R2lettuce = 0.723, P < 0.05). The result...

A comprehensive health risk assessment associated with bioaccumulation of heavy metals and nutrients in selected macrophytes of Loktak Lake, Manipur, India
Environ Sci Pollut Res Int. 2023 Sep 15. doi: 10.1007/s11356-023-29606-2. Online ahead of print.ABSTRACTThe Loktak Lake, a Ramsar site in Northeast India, is known for its rich biodiversity that includes a variety of macrophyte species, most of which have not been studied for their phytoremediation capacities and potential toxicity via consumption of the edible species. Therefore, a comprehensive assessment was conducted to evaluate the accumulation of selected heavy metals and nutrients in 10 dominant macrophyte species growing in Loktak Lake and to assess the potential health risks associated with consumption of the edib...

Maternal exposure to sunlight-irradiated graphene oxide induces neurodegeneration-like symptoms in zebrafish offspring through intergenerational translocation and genomic DNA methylation alterations
This study demonstrates that maternal exposure to SL-PEI-GO induces clear neurodegeneration-like symptoms in offspring through both the intergenerational translocation of nanomaterials and differential DNA methylation. These findings may provide new insights into the health risks of nanomaterials altered by nature conditions.PMID:37690221 | DOI:10.1016/j.envint.2023.108188

Effects of blast furnace slag on the immobilization, plant uptake and translocation of Cd in a contaminated paddy soil
This study was conducted to investigate the remediation effects of blast furnace slag (BFS) on the bioavailability of Cd in a contaminated paddy soil from a perspective of soil solution chemistry. Batch experiments, pot culture experiments, and principal analysis (PCA) were used to study the effects and mechanisms of BFS addition changing Cd chemical behavior and Cd toxicity. Results indicated that BFS facilitated Cd adsorption in soils, increased pH, Eh, and EC values in soil solution, whereas reduced dissolved Cd content. BFS amendment was efficient in decreasing root Cd intake and Cd upward transport in rice plant, with...
