Abstract Most vegetable crops are severely affected by the uptake of heavy metals from soil. Heavy in bodies generate reactive oxygen species (ROS) that unbalance antioxidant defense system. This study was initiated to determine physiological and biochemical characteristics spinach plants grown on soil contaminated with responding Bacillus cereus aerius were isolated metals. metal contamination led a significant reduction seed germination, seedling biomass, protein, total nitrogen content soils compared control soils. In contrast, increase metallothioneins enzymes observed. Plants inoculated B. significantly reduced oxidative stress induced improving germination (%), growth, nitrogen, protein content.

Published: April 14, 2025

Heavy metal (HMs) toxicity has severely impacted wheat production and is considered an emerging threat to human health due bioaccumulation. The application of organic inorganic amendments proven effective in mitigating HM’s phytotoxicity by limiting their mobility soil plants. A pot experiment was conducted evaluate the efficiency biochar (BC), bentonite (BN), rock phosphate (RP), both individually combination, alleviating lead (Pb) enhancing growth, physiological attributes. present investigation revealed that BC, BN, RP, combined mineral (MBAs) at 1.5% level significantly enhanced growth along with reducing DTPA-extractable Pb 30.0–49.8% uptake roots 15.7–37.5% shoots 34.5–48.5%. Antioxidant enzymatic activities were improved, stress indicators reduced under stress, including hydrogen peroxide (H2O2) 50.7 81.0%, malondialdehyde (MDA) levels 16.0 74.9%, proline content 34.5 64.0%, respectively. effectiveness treatments described descending order viz.

Environmental protection, global food security, and nutritional quality are critical issues for worldwide sustainable development. Plums (Prunus domestica L.), well-known their rich content distinct phytochemical profile, have received increased attention due to potential health benefits. The present study evaluates the ecological conventional management systems of parameters in three plum varieties—Tuleu Gras, Record, Centenar—and establishes suitable practices improve fruit yields. morphometric features (color, firmness, soluble solid content, titratable acidity, total sugar) were analyzed during raw state, while different fruit-sample extracts assessed compounds heavy metal concentrations, specifically, zinc, copper, nickel, cadmium. results show a wide variability examined characteristics among that differentially accumulated throughout ripening phase significantly influenced value fruit. application an practice yielded small fruits (38 g) maintained more consistent vigorous color compared with system (83 g). Moreover, plums higher antioxidant activities, polyphenols, flavonoids (21.70–25.54 µM Trolox/g dw, 3.89–7.76 mg GAE/ g 1.45–3.65 CE/g respectively). Among metals fruit, copper exhibited highest concentrations (0.83–1.21 mg/kg), cadmium was detected at lowest levels (0.006–0.009 mg/kg). implications metals, by calculating estimated daily intake (EDI), target hazard quotient (THQ), index (HI), both adults children also analyzed. EDI values elements followed order Cu > Zn Ni Cd no concern human (THQ HI < 1). According this study’s findings, plums, providing compelling argument adopting agricultural practices. These highlight importance selecting practices, not only safeguard environment but ensure high-quality products consumption.
