During natural succession, there are decreases in the concentrations of toxic and harmful substances soil. Although environmental conditions improved, resulting spatial distribution pollutants soil remains unclear. Detection final heavy metals would enable pollutant migration transformation be better understood, thereby supporting restoration safety risk assessment mining areas. In this study, 23 were measured at various stages succession different layers during an abandoned area. Variations metal among vertical levels determined. The lead (Pb), zinc (Zn), cadmium (Cd) first increased then decreased succession; they mainly distributed surface layer late stage succession. ferrophilic (i.e., copper [Cu] nickel [Ni]) significantly total amount direction was influenced by cation exchange capacity (CEC) stratification (FC), which affected indirectly modifying their magnetic susceptibility (MC). At (Stage) positively correlated with soil, effects carbon (TC) humic acid (HA) Generally, migrated to upper strongly physical chemical properties These findings provide a scientific basis for understanding plant community on improvement

Heavy metals (HMs) contamination is a serious environmental concern in different parts of the world. In this study, two indigenous phytoextractors, Sida acuta and Melissa officinalis L. were used assisted with plant growth promoting bacteria (PGPB) vermicompost by-product (vermicast) produced for remediation purposes. The concentration heavy metal accumulation plants determined using atomic absorption spectrophotometry analyzed by canonical discriminant analysis (CDA). Pre- post-remediation physico-chemical properties soil was conducted. M.

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.

Abstract Many years ago, widespread and ineffective technologies led to significant ecological contamination, primarily due heavy metals (HMs), particularly lead (Pb) cadmium (Cd). Plant growth in contaminated calcareous soil is a challenge for all the growers worldwide. Several organic inorganic amendments are used by researchers different types of soils. However, their impact on with toxic alkaline reaction still unclear. Therefore, current pot experiment investigates relative effect (wheat straw biochar farmyard manure) at 10 20 t ha −1 (diammonium phosphate gypsum) 100 150 kg NPK availability, matter, properties, maize under Cd Pb stress. Highest pH (7.61), electrical conductivity (0.25 dS m ), matter (1.40%), plant height (92 cm), shoot dry weight (41 g), root (5.5 g) were observed because application . While highest total nitrogen (N) (0.13%), phosphorus (P) (8.16 mg ) recorded diammonium , moreover, manure increased potassium (K) (108.14 ). Biochar greatly reduced bioavailability high immobilization index, that is, (52%) (43.79%) lower concentrations roots shoots as well. A negative correlation was identified between pH, Cd, Pb, demonstrating positive terms reduction enhancing found be most effective amendment improvement stress condition.

Mining activities often contaminate soils with heavy metals, generating environmental and health risks. This study investigates the ecotoxicity of muddy (Mw) sandy (Sw) mining wastes on Phaseolus vulgaris assesses impact five locally sourced biochar amendments plant growth soil pore water (SPW) properties. Most biochars improved retention, except for argan nut shells (An) biochar, highlighting importance feedstock type. Sw supported better than Mw regardless addition, due to textural differences. Palm fronds (Pf) significantly enhanced surface leaf area in Sw. SPW analysis revealed that affected pH electrical conductivity (EC) differently across types. consistently increased pH, while Sw’s was biochar-dependent. A significant 5.1-fold EC increase recorded amended Pf. All reduced Pb availability at planting, Cu decreased harvest. In Mw, Pb, Zn, Cu, uptake accumulation were unaffected by a slight reduction observed roots. germination test Lepidium sativum confirmed these findings, particularly inhibition An. dual approach highlights toxicity biochars’ potential as remediation programs.
