Plastic mulch films support global food security, however, their composition and the potential release rates of organic, metal metalloid co-contaminants remains relatively unknown. This study evaluates low molecular weight organic additives, content leaching from density polyethylene (LDPE) biodegradable plastic films. We identified 59 non-intentionally added substances in new LDPE (39.8 mg m-2) 60 (129 m-2). The compounds high concern for ecosystem human health (e.g. phthalates, organophosphite antioxidants) was comparable to those (fatty acids, fatty amides, alkanols).

Zn is an indispensable nutrient for crops that usually presents low bioavailability. Different techniques have been proposed to improve the bioavailability of Zn, including use nanofertilizers. The objective study was evaluate applications drench (D) and foliar (F) ZnO nanoparticles (NZnO) compared those ionic Zn2+ (ZnSO4) in lettuce. plants cv. Great Lakes 407 produced pots 4 L with perlite-peat moss (1:1) under greenhouse conditions. treatments consisted NZnO replaced total provided a Steiner solution, as follows: (100%D) (control); (50%D+50%F); (100%D); (75%D); (50%D); (75%F) (50%F). Four were made frequency 15 days. 75 days after transplant (DAP), fresh dry biomass, chlorophyll a, b, β-carotene, phenolics, flavonoids, antioxidant capacity, vitamin C, glutathione, H2O2, protein, enzymatic activity PAL, CAT, APX, GPX evaluated. mineral concentrations (N, P, K, Ca, Mg, S, Cu, Fe, Mn, Mo, Ni, Si) leaves roots also determined. results showed that, Zn2+, promoted increases biomass (14-52%), chlorophylls (32-69%), compounds such C. enzymes like CAT well concentration Si increased NZnO. A better response found most variables equivalent 50-75% applied conventionally. These demonstrate replacement possible, promoting fertilizer efficiency nutraceutical quality

Nano-Hydroxyapatite and ZnO-NPs Mitigate Pb Stress in Maize

Agronomy, Journal Year: 2023, Volume and Issue: 13(4), P. 1174 - 1174

Published: April 20, 2023

Heavy metals (HMs) stress, particularly lead (Pb) is one of the most hazardous environmental stresses that can negatively affect plants’ growth, yield, and quality. Therefore, effects zinc oxide nanoparticles (ZnO-NPs; 50 mg L−1), nano-hydroxyapatite (HP-NPs; kg−1), their combination on physiological, yield traits maize grown in soil contaminated with Pb (i.e., 100 kg−1) were investigated. The results showed stress significantly reduced plant leaf area by 50.9% at 40 days after sowing (DAS), 55.5% 70 DAS, 54.2% DAS comparison to unstressed plants (control). However, combined application ZnO-NPs (50 L−1) + HP-NPs adverse growth terms increasing 117.6% Pb-contaminated (100 kg−1). Similarly, resulted increments total chlorophyll content 47.1%, photosynthesis rate 255.1%, stomatal conductance 380% obtained from stressed Pb. On other hand, antioxidants such as sodium dismutase (SOD; 87.1%), peroxidase (POX; 90.8%), catalase (CAT; 146%), proline (116%) increased a result compared plants. Moreover, N, P, K, Zn contents whole under decreased 38.7%, 69.9%, 46.8%, 82.1%, respectively, those control. Whereas treatment uptake nutrients and, consequently, highest values ear weight, grain harvest index obtained. Furthermore, biomass 77.6% grains 90.21% exposed stress.

Nanomaterials (NMs), particularly ZnO nanoparticles (NPs), show great promise in sustainable agriculture for enhancing crop production, mineral nutrition, and food safety. However, custom synthesis of NMs to optimize performance is still a bottleneck. This study synthesized three types (NPs) (nZnO-1, nZnO-2, nZnO-3) with different particle size, charge, dissolution properties were foliar-applied wheat under field conditions. Foliar application nZnO-3 significantly increased grain by 15.2% biological yield 9.5% compared that the unamended control. Both nZnO-2 improved Zn content whole (21.0 15.6%, respectively) starchy endosperm (31.8 13.1%, respectively), enhanced bioavailability (40.9 43.3%, estimated daily intake (EDI) (55.1 23.8%, respectively). Impressively, also reduced Cd concentration (17.2%) although it did not affect level flour. Additionally, all treatments levels crude protein (5.2–15.7%) other nutrients (e.g., S, Fe, Mn) grains. These findings underscore potential tailored NPs biofortification point toward approach agricultural production through controlled platform.
