Maize and wheat grains are at significant risk of accumulating excessive heavy metals in acidic soils, but relatively few comparative studies have been conducted on the two. This study employed Spearman correlation analysis, random forest modeling, structural equation modeling to systematically investigate interdependences between soil properties metal accumulation (Cd, Cr, As, Pb, Hg) cereal grains. The results revealed distinct patterns content sequences maize grains: exhibited Cr > Pb As Cd Hg, while followed Hg. Bioconcentration factor (BCF) differed significantly, showing Hg versus wheat. Soil cation exchange capacity demonstrated strongest influence both crops. Arsenic mechanisms displayed species-specific dependencies, with primarily regulated by organic matter clay content.

Moreover, showed responses properties, particularly their Cd. By addressing contamination this work supports development safer agricultural practices improved crop quality control.

This study investigated the morphological dependence of ZnO nanostructures, specifically nanotube- and nanorod-based electrodes, on their electrochemical performance for detection lead ions (Pb2⁺) in aqueous solutions. The results demonstrate that nanotubes exhibit significantly enhanced sensitivity compared to nanorods during CV measurements. During SWV measurements, (116.79 mA·mM−1) a lower limit 0.0437 μM were determined. hollow, high-aspect-ratio structure provides larger active surface area facilitates better ion accessibility, resulting superior electron transfer efficiency catalytic activity. These underscore critical role morphology optimizing ZnO-based sensors. Analysis real water samples from various natural reservoirs revealed no detectable lead, while was identified exclusively artificially prepared containing exposed hunting shot. Over 30-day period, sensor retained over 95% its initial when stored under vacuum conditions, demonstrating minimal signal degradation. Under ambient stability loss attributed moisture adsorption porous nanostructure. also displayed outstanding reproducibility, with current response variations across multiple probes remaining within 4%. cost-effective simple fabrication process nanostructures further highlights potential scalable production, environmental monitoring, integration into portable sensing devices.
