Agricultural soil is gradually becoming a primary sink for metal-based nanoparticles (MNPs). The uptake and accumulation of MNPs by crops may contaminate food chain pose unexpected risks human health. Here, we investigated the fate transformation CuO (NPs) in soil-rice system during rice lifecycle. results show that at maturation stage, 1000 mg/kg NPs significantly decreased redox potential 202.75 mV but enhanced electrical conductivity 497.07 mS/cm compared to controls. Moreover,...
The release of nanoparticles (NPs) to the environment poses an increasing potential threat biological systems. This study investigated phytotoxicity and accumulation copper oxide (CuO) NPs Elsholtzia splendens (a Cu-tolerant plant) under hydroponic conditions. 50% effective concentration (EC50) CuO E. was about 480 mg/L, implying tolerance NPs. Cu content in shoots treated with 1000 mg/L much higher than those exposed comparable 0.5 soluble bulk particles. NPs-like deposits were found root...
Many studies have shown the effect of solution chemistry on environmental behavior metal-based nanoparticles (NPs), except CuO NPs. Here, we investigated agglomeration, sedimentation, dissolution, and speciation NPs by varying pH, ionic strength, valence, natural organic matter (NOM). The results showed that as pH moved away from 6, size agglomerates decreased, along with enhanced NP suspension stabilization, due to increase electrostatic repulsive force. Increasing strength valence...
The waterlogging environment generally results in the deposition of iron plaque on plant roots, which may impact fate metal-based nanoparticles. Here, we investigated influence uptake, translocation, and transformation copper oxide nanoparticles (CuO NPs) rice plants. show that presence dramatically reduced Cu contents roots shoots by 89% 78% those without under 100 mg/L CuO NP treatment. Meanwhile, accumulation plants was negatively related to amount plaque. X-ray absorption near edge...
Flavonoids are natural polyphenolic compounds produced by many aquatic plants and released in their environments. In this study, the effects of several flavonoids on cyanobacterial Microcystis aeruginosa, especially relation to cell growth, photosynthetic activity, morphology, membrane integrity, were investigated. Significant growth inhibition was observed when cyanobacteria exposed three flavonoids, namely, 5,4'-dihydroxyflavone (DHF), apigenin, luteolin. Luteolin reduced effective quantum...
The rhizosphere is an essential pathway for the uptake of metal-based nanoparticles (MNPs) by plant roots. However, interaction between root exudates and MNPs still unclear. In this study, we initially identified major low-molecular-weight organic acids (LMWOAs) in rice using hydroponics. Then, individual LMWOAs were added to CuO nanoparticle suspensions investigate their effects on environmental behavior MNPs. results showed that both variety concentration impacted aggregation,...
