Heavy metals and metalloids (HMs) contamination in the environment has heightened recently due to increasing global concern for food safety human livability. Zinc (Zn2+ ) is an important nutrient required normal development of plants. It essential cofactor vital enzymes involved various biological mechanisms Interestingly, Zn2+ additional role detoxification HMs plants its unique biochemical-mediating several soil plant processes. During any exposure high levels HMs, application would confer greater resilience by decreasing oxidative stress, maintaining uptake nutrients, photosynthesis productivity optimising osmolytes concentration. also ameliorating toxicity regulating metal through expression certain transporter genes, targeted chelation translocation from roots shoots. This review examined roles nano Zn described their involvement alleviating Moving forward, a broad understanding uptake, transport, signalling tolerance /zinc nanoparticles will be first step towards wider incorporation into agricultural practices.

Progress and prospects for remediation of soil potentially toxic elements pollution: A state-of-the-art review

Environmental Technology & Innovation, Год журнала: 2024, Номер 35, С. 103703 - 103703

Опубликована: Июнь 7, 2024

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.

The experimental study was contrived to characterize two zinc-solubilizing bacteria (ZSB), namely BMRR126 and BMAR64, their role in zinc (Zn) biofortification of rice. These solubilized Zn profoundly, determined qualitatively by halo-zone formation on a solid medium quantitatively liquid broth AAS SEM-EDX. lowering pH contact angle assessment the unveiled establishment acidic conditions suitable for solubilization. characterization both isolates basis 16S rRNA gene analysis identified as Burkholderia cepacia Pantoea rodasii, respectively. strains were also found have some plant probiotic traits phosphate solubilization, production siderophore, indole acetic acid (IAA), exopolysaccharide (EPS), ammonia. field experiments performed at diverse locations under all treatments; simultaneous use BMAR64 with oxide (ZnO) resulted highest growth productivity paddy crop. utmost achievement grain estimated treatment (T9) (25.07 mg/kg) containing consortium along ZnO Terai region. single ZSB bioinoculant (T7) showed an elevated amount rice (33.25 Katchar soil parameters (pH, EC, organic carbon, NPK, available Zn, dehydrogenase activity) positively influenced bacterial treatments compared uninoculated control. Our clearly accentuates need solubilizing (ZSB) provide benefits Zn-biofortification different regions.
