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.

Plant activators have emerged as promising alternatives to conventional pesticides for crop disease manage-ment due their unique mode of action. By priming the plant's innate immune system, these compounds can induce systemic acquired resistance against a broad spectrum pathogens without directly inhibiting proliferation. Key advantages plant include prolonged defense activity, lower effective dosages, and negligible risk developing pathogen resistance. Among various defensive pathways tar-geted, salicylic acid (SA) signaling cascade has been extensively explored, leading successful devel-opment commercial like benzothiadiazole widespread application in protection. While action sites many SA-targeting preliminarily mapped different steps along pathway, comprehensive understanding precise mechanisms remains elusive. This review provides historical perspective on activator development outlines diverse screening strategies employed across multiple levels, from whole-plant bioassays molecular transgenic approaches. We expound intricate components, biological relevance, regulatory circuits governing SA while criti-cally examining structural features, bioactivities, proposed modes classical such derivatives, analogs, other small molecules. Insights field trials as-sessing practical applicability are also discussed. Furthermore, we highlight current status, challenges, future prospects realm globally, with focus recent en-deavors China. Collectively, this aims synthesize existing knowledge provide roadmap research toward more potent mechanistically understood activa-tors that fortify immunity disease.

This study investigates efficacy dead cells from Microcystis aeruginosa blooms, collected agricultural drainage water reservoir, in removing cadmium, lead, and zinc aqueous solutions, simultaneously addressing mitigation M. bloom. Some physical characterization biomass was performed, including scanning electron microscope (SEM) which revealed that, form a dense, amorphous cluster, energy-dispersive X-ray (EDX) spectroscopy confirmed that carbon, oxygen, nitrogen are predominant elements biomass, Fourier transformation infrared (FTIR) identified several active function groups, hydroxyl, aliphatic C–H amide I II bands, carboxylate carbonyl (C=O). Key factors influencing process were examined. Under optimal conditions—pH 6, biosorbent dose 0.3 g, contact time 90 min, primary level 100 mg/L temperature 35 °C (313K)—a maximum removal efficiency exceeding 90% achieved. Isothermal analysis Cd(II), Pb(II), Zn(II) followed Langmuir isotherm model (R 2 = 0.96, q max > 67 mg/g). Kinetic studies indicated pseudo-second-order best described 0.94 e 81.3 mg/g.), suggesting dominant chemisorption mechanism. Thermodynamic is spontaneous endothermic. findings highlight potential as low-cost, sustainable heavy wastewater treatment applications.
