Abstract The study aims to assess the concentrations of heavy metals in road dust from different land uses Aizawl, Mizoram, by implementing a methodology that includes descriptive statistics (mean, median, and standard deviation), one-way ANOVA, Pearson correlation coefficient. Enrichment contamination factors were also determined identify sources level pollution area. health risks for children adults assessed based on established guidelines. From study, ranged as follows: Cr (18.19 36.28 mg/kg), Pb (20.64 27.12 Cd (-1 0.06 Ni (32.32 47.91 Cu (-0.51 32.49 Zn (30.80 119.84 mg/kg). highest concentration was found agricultural area (47.91 possibly due jhum cultivation practices. When compared with background values, levels lower, while Pb, Ni, exceeded values 94.66%, 41.47%, 228.54%, respectively, indicating anthropogenic activities. A ANOVA analysis showed significant difference metal across various use areas. Except ecological risk assessment indicated low risk. associated non-carcinogenic effects humans, especially children, other elements within safe levels. Proper management safety measures still needed improve environmental impact individuals living

Agricultural soils and crops are increasingly vulnerable to contamination by potentially toxic elements (PTEs), exacerbated anthropogenic activities. This study aimed evaluate the human health risks associated with PTEs (Cd, Cr, Hg, Cu, As, Zn, Ni) in agricultural soil rice grains from different cultivated paddy Northern Cameroon. In this research, a modified Susceptible-Infected-Removed-Susceptible (SIRS) model, based on mathematical derivatives, was employed alongside carcinogenic non-carcinogenic risk assessment method through various indices. A total of 100 samples including (Oryza sativa) were analysed using inductively coupled plasma–mass spectrometry (ICP-MS) (Perkin Elmer Nixon 300Q). The mean concentration Cr (43.56 mg/kg) Vele, as well (43.48 Ni (36.24 Zoulla, exceeded geochemical background values. concentrations Cd, Ni, Zn within limits set WHO/FAO, except for Djogoidi, which WHO/FAO recommended value 0.1 mg/kg. Additionally, content Droumka twice high value. Similarly, bioaccumulation factor (BAF) (3.53 mg/kg), Cu (3.25 (2. 59 Djogoidi Cd (4.44 (3.22 (2.44 one two-fold higher than 1 denoting potential bioaccumulates metals grains. Also, (CRFS) indicates Hi (4.49E+02) children exceeding critical (threshold = 1) carcinogenicity standards, indicating very risk. results dynamic model also confirm susceptibility mortality over time due ingestion contaminated crops. is particularly evident following PTEs: show an increasing trend I_h (t), increase, α 0.25. Therefore, targeted mitigation measures necessary be adopted food protection pollution area.

The ‘Cavendish’ banana is cultivated for its flavor and nutritional value, but climacteric nature leads to rapid ripening reduced shelf life. Preserving postharvest quality crucial minimizing losses ensuring consumer satisfaction. Nanoparticles such as ZnO Ag 2 O have shown promise in extending the life maintaining of perishable fruits. Therefore, this study aimed evaluate efficacy ZnO- Ag₂O-enriched edible coatings on physicochemical bananas stored at ambient temperature. Bananas were treated with five different formulations: (1) moringa extract alone (MG), (2) combined carboxymethyl cellulose glycerol (MG + CMC GLY), (3) nanoparticles (Ag O), (4) (ZnO), (5) a combination ZnO). effects key parameters, including weight loss, color retention, total soluble solids, acidity, pH, peel structure, assessed. At end storage period, fruits Ag₂O demonstrated significantly lower decay incidence 44.44% than control (100%). Similarly, nanoparticle-enriched treatments maintained higher L* (1.46-fold), b*(1.38-fold), h o (1.11-fold) values treatment. Remarkably, composite formulation showed most significant positive stomatal cell integrity toward improving quality. This highlights potential ZnO/Ag composites effective enhance extend life, providing promising approach reduce ensure fruit during transportation.
