The mechanisms of cadmium (Cd) uptake and redistribution throughout the peanut lifecycle remain unclear. This study employed multi-isotope labeling techniques in hydroponic soil-foliar systems, revealing that Cd during podding (Cdp) constituted 73.7% kernel content, whereas contributions from flowering (Cdf) seedling (Cds) stages were 22.2 4.1%, respectively. Stem-stored (Cdstem) contributes 53.2% to accumulation, while leaf-stored (Cdleaf) 46.8%. Prestored Cdf shoots demonstrated most efficient transport pods, approximately twice Cds Cdp. predominantly stored leaves (51.0%), Cdp mainly stems (46.3%), 2.8 times its presence (16.5%), indicating distinct root-stem-kernel translocation. In transfer shoot 29.3% Cdleaf 25.0% Cdstem exported. provides novel insights into dynamics peanuts, establishing a foundation for future regulation strategies.

Rapid economic development has led to an alarming increase in soil pollution by potentially toxic elements (PTEs), significantly reducing productivity and posing long-term threats sustainable agriculture human well-being. Over the past two decades, it been observed that PTEs severely impacted biodiversity, with damage rates of 94.7 % plants, 77.4 humans, 68.4 animals. In response, various remediation technologies have developed, considering factors such as practical applicability, treatment duration, ecological safety. Microbial shown a removal efficiency ranging from 32.0 95.2 %, while multi-technology combined approaches demonstrated broader efficacy, 18.7 381 %. However, selection suitable technology must also consider cost ensure efficient contaminant removal. This review provides comprehensive overview local international status, sources, hazards associated PTEs, well environmental influencing their migration. It examines detoxification mechanisms plants microbial evaluates strengths weaknesses physical, chemical, biological, methods. Furthermore, underscores requirements opportunities for developing effective techniques. The insights presented here are crucial agronomists strategies interdisciplinary research into integrated emission sources pathogenesis, thereby enhancing efforts safeguard Earth's environment.

Nature reserves are integral to sustaining ecological balance, functioning like a precise regulator, where various species depend on and constrain one another collectively form stable ecosystem. Nevertheless, in the wake of economic development, pollutants heavy metal contamination have insidiously emerged, imperceptibly influencing all these processes. To understand risk metals an estuarine nature reserve, this study focused Yellow River Delta Reserve (YRDNNR) analyzed distribution, potential environmental risks, possible sources (Mn, Cu, Zn, Cr, As, Cd, Pb) surface sediments region. The results indicated that YRDNNR was rich As with Cd presenting most substantial risk. Further analysis suggested high levels could be ascribed agricultural activities. This also found practices made significant contribution carcinogenic pose certain risks natural environment human health. More in-depth monitoring testing should carried out, measures adopted accordance their development. Moreover, systematic regulation fertilizer pesticide use, along enhancements farmers’ awareness, is great significance alleviating pollution hazards. findings carry implications for conservation coastal wetlands, serving as critical alert proliferation other areas delta.

Employing crop cultivars with low cadmium (Cd) accumulation and high yield is an effective strategy for the sustainable safe utilization of Cd-contaminated farmland. However, current understanding peanut cultivars, particularly under field conditions, limited. This study identified low-Cd their rhizosphere microbial characteristics in acidic alkaline fields moderate Cd contamination. The results indicated that LH11, FH1, LH14, YH9414 exhibited yield, kernel content reduced by 27.27% to 47.28% increased 9.27% 14.17% compared cultivar SLH. Among them, FH1 was validated achieve production two fields. A unique community formed recruitment diverse microbes, such as Alphaproteobacteria, Acidobacteria, Gemmatimonadetes, Chloroflexi, soil which might be associated immobilization promotion plant growth. Functional predictions further these findings, revealing enhanced functional pathways related proliferation, stabilization, detoxification. provides valuable germplasm resources agriculture Cd-polluted soils elucidates different conditions. These findings are important targeted management contaminated farmland ensuring food production.
