The phytoremediation potential of the halophytic plant, Tamarix smyrnensis (T. smyrnensis), was examined in toxic metal spoils assisted by biochar and irrigation air nanobubbles. substrate (spoil) used present study derived from areas close to laterite (Ni-containing ores) mines. efficiency addition two rates (5 t/ha 20 t/ha) improve microbial properties stabilize soil aggregates also examined. Furthermore, effect with air-nanobubble-supplemented water evaluated for remediation spoils. physiological condition plant species investigated terms biomass, height, chlorophyll content, antioxidant enzymes. alkali heavy accumulation their distribution parts were assessed explore whether metals could accumulate root further translocate aboveground tissues. growth T. not adversely affected its cultivation lateritic spoil, highest rate exhibited a beneficial on weight (aerial subterranean biomass). application led significant increases total showing 97.6% increase when is alone 136% combined nanobubble irrigation. Remarkably, only combining nanobubbles low supplementation did translocation tissues occur as factor estimated be greater than unity (TF > 1). bioconcentration factors remained below 1.0 (BCF < 1) across all treatments, demonstrating limited mobilization despite amendments. Finally, increased slightly but substantially uptake metals, which showed decrease compared control groups lower dosage utilized.

The volumetric mass transfer coefficients (kLa) of oxygen during sorption and desorption were analyzed using nanobubbles (NBs) air pure under various experimental conditions. results showed that NBs achieved an increase in dissolved (DO) levels absorption, reaching peaks 30–34 mg∙L−1 stabilizing at 31.3 ± 0.2 mg∙L−1, with a coefficient 0.105 0.002 min−1. In comparison, lower efficiency, peak DOs 8∙10 kLa 0.048 0.001 studies, had higher DO retention, reducing from 30.0 to 15.0 300 min, 0.042 0.003 min−1, while decreased more rapidly, 0.028 When was used, outperformed both absorption desorption, stability. addition, the show residence time has important impact on performance NBs, showing direct influence flow dynamics surface/to/volume ratio influences value kLa. highlight superior versus terms efficiency stability effect NB composition applications requiring efficient transfer, given promising prospects for development advanced aeration technologies industrial environmental contexts.

Irrigation Water Treated with Oxygen Nanobubbles Decreases Irrigation Volume While Maintaining Turfgrass Quality in Central Chile

Grasses, Год журнала: 2025, Номер 4(1), С. 6 - 6

The efficient use of water resources is a growing priority in multiple sectors, including the turfgrass industry. Nanobubbles (NB) represent an innovative technology that, by enriching solutions with various gases, offers significant benefits several industrial areas. In crop irrigation, they have been shown to increase dissolved oxygen root zone and thereby boost yields. objective this study was evaluate impact NB irrigation on quality, considering different levels restriction (0%, 30%, 50% daily evapotranspiration), compared conventional irrigation. During summer 2024, trials were conducted using turf quality indices based multispectral reflectance RGB digital image analysis. results showed that allowed for reduction without compromising reaching values similar treatments restriction. contrast, treatment same but (WNB50%) deterioration quality. This shows as tool optimize use, great potential applications landscape green areas, promote efficiency, reduce costs associated
