Devising exceptional S-scheme heterojunction photocatalysts utilized in annihilating pharmaceuticals and chromium contamination is significant for addressing the problem of global water pollution. In this work, a chemically bonded Mn0.5Cd0.5S/BiOBr heterostructure with oxygen vacancies ingeniously developed through facile in-situ solvothermal synthesis. The designed exhibits eminently reinforced photo-activity destruction tetracycline hydrochloride Cr (VI) as compared its individual components. This substantial photo-redox performance amelioration benefitted from creation an intense internal electric field (IEF) via supplying powerful driving force migration highway by interfacial chemical bond to foster electron/hole disintegration. More intriguingly, IEF at hetero-interface drives fast consumption photo-induced holes Mn0.5Cd0.5S photoelectrons BiOBr, profoundly boosting enrichment active photo-carriers sparing photo-corrosion Mn0.5Cd0.5S. Furthermore, anti-interference property can work efficiently real matrices. Multiple uses recycled Mn0·5Cd0·5S/BiOBr evidence prominent robustness stability. achievement indicates vast potential photosystems structural defects design photo-responsive materials effective wastewater treatment.

Potential Toxic Mechanisms of Neonicotinoid Insecticides in Rice: Inhibiting Auxin-Mediated Signal Transduction

Environmental Science & Technology, Journal Year: 2023, Volume and Issue: 57(12), P. 4852 - 4862

Published: March 16, 2023

Inappropriate application of pesticides not only causes sub-lethal effects on ecosystem service providers but also reduces crop yield and quality. As a xenobiotic signal molecule, may interact with transduction receptors in crops, resulting oxidative damage even metabolic perturbations. We discovered that three neonicotinoid insecticides (NIs), namely, imidacloprid, thiamethoxam, clothianidin, at 0.06-0.12 kg ai/ha significantly inhibited the auxin pathway rice leaves, thereby reducing intracellular (IAA) content. Molecular simulation further confirmed NIs occupied binding site where transporter-like proteins 1 (LAX11) 2 (LAX12), which Thr253 Asn66 LAX11, as well Thr244 Asn57 LAX12, were bound to nitroguanidine via H-bonds. Meanwhile, LAX11 LAX12 interacted aromatic Moreover, phenylpropanoid biosynthesis was disturbed because pathway. Notably, peroxidase-coding genes downregulated maximum value greater than 10-fold, decreased antioxidant metabolites flavone (37.82%) lignin content (20.15%). Ultimately, biomass reduced by up 25.41% due decline IAA capacity. This study deeply explored molecular mechanism perturbations crops stressed pesticides, thus providing scientific basis for pesticide environmental risk assessment agricultural product safety.

Published: Jan. 1, 2024

The coastal region of Agadir, Morocco, is subject to various human activities and industrial development, raising concerns about potential heavy metal pollution in the surrounding seawater. This study aimed assess levels metals seawater along coast Agadir by conducting sampling at six sites: Aglou Beach (S1), Wassay (S2), Douira Desalination Plant (S3), (S4), Anza (S5), Cap Ghir (S6). In addition analysis, physicochemical parameters such as temperature (T°C), pH, conductivity, salinity, chlorides, sulfates, nitrate, nitrite were measured further understand overall water quality these areas. concentration selected was range 10 – 70 μg/l, 24 440 20 85 40 1500 μg/l 400 980 for Cd, Hg, Pb, Zn, Fe, respectively. maximal recorded from site 5, minimum location 6. pH ranges 8.18–8.35 stations 6 1, Electrical conductivity values surface ranged 44,254 50,210 μS/cm 5. maximum salinity concentrations 30.29 34.37 g/L sites 4 3, Our results revealed that nearly identical across all zones apart Douira. probably related anthropogenic (industrial, wastewater, desalination plants, etc.…) two

Antibiotics-heavy metals combined pollution in agricultural soils: Sources, fate, risks, and countermeasures

Green Energy & Environment, Journal Year: 2024, Volume and Issue: unknown

Published: July 1, 2024

Agricultural soil is related to food security and human health, antibiotics heavy metals (HMs), as two typical pollutants, possess a high coexistence rate in the environmental medium, which extremely prone inducing antibiotic-HMs combined pollution. Recently, frequent activities have led more prominent antibiotics-HMs contamination agricultural soils, especially production spread of antibiotic resistance genes (ARGs), metal (MRGs), resistant bacteria (ARB), complexes (AMCs), seriously threaten ecology health. This review describes main sources (Intrinsic manmade sources), composite mechanisms (co-selective resistance, oxidative stress, Joint toxicity mechanism), fate potential risks (soil ecological health risks) HMs soils. Finally, current effective source blocking, transmission control, attenuation strategies are classified for discussion, such application additives barrier materials, well plant animal remediation bioremediation, etc., pointing out that future research should focus on whole chain process "source-process-terminal", intending provide theoretical basis decision-making reference research.
