Introduction: Soil pollution directly impacts food quality and the lives of both humans animals. The concentration heavy metals in Egypt’s drain-side soils is rising, which detrimental to soil crops. key reducing effects on ecosystem having accurate maps spatial distribution subsequent use environmentally sustainable remediation approaches. objective this work assess contamination utilizing mapping metals, determine levels using Principal Component Analysis (PCA), calculate severity potential for bioremediation surrounding main drain Bahr El-Baqar. Furthermore, evaluating capacity microorganisms (bacteria, fungi, “Actinomycetes) degrade elements soil. Methodology: 146 sample locations were randomly selected near El-Baqar examine degree Ordinary Kriging (OK), method was used map analyze by seven (Cr, Fe, Zn, Cd, Pb, As, Ni). Modified (mCd) PCA research area’s levels. process involved isolating, identifying, classifying present study area. findings showed that variography suggested Stable model effectively matched pH, SOM, Cd values. exponential proved suitable predicting Pb Ni, while spherical appropriate Cr, Zn. Results: revealed three contamination, with an extremely high (EHDC) affecting approximately 97.49% EHDC exhibited average concentrations metals: 79.23 ± 17.81 20,014.08 4545.91 201.31 112.97 1.33 1.37 40.96 26.36 211.47 13.96 46.15 9.72 Ni. Isolation identification a significant influence breakdown organic inorganic pollutants environment. demonstrated exceptionally removal efficiency As reached 100%, achieved Rhizopus oryzae , Pseudomonas aeruginosa Bacillus thuringiensis . Conclusion: This has designated management zones pollutants, geo-identified them, found could significantly reduce

The rhizosphere hosts diverse microbes crucial for plant growth. This is because roots secrete organic compounds, thereby enriching the with essential nutrients. Biochar improves soil quality, while nano-biochar shows promise in contaminant adsorption. Its production from biochar easily achievable through top-down methodologies including hydrothermal synthesis, ball-milling, sonication, and centrifugation. advantages of employing are evident several aspects. Nano-biochar exhibits enhanced properties such as greater surface area, increased porosity, reactivity compared to bulk-biochar. area allows adsorption capacity, enabling effectively immobilize contaminants environment. In this review, detailed interactions applications summarized. interacts by electrostatic interaction, cation-π redox reactions, influencing microbial communities resilience. can adsorb rhizosphere, heavy metals pollutants. Thus, it helps alleviate abiotic stresses, nutrient availability, supports Furthermore, mechanistic processes oxidation, mineral dissolution, matter release, mechanical fragmentation discussed, culminating ageing formation, which creates a conducive environment microorganisms. review examines nano-biochar-rhizosphere interactions, highlighting their effects on plant-soil dynamics Future research should address synthesis scalability safety concerns unlock nano-biochar's potential sustainable agriculture environmental management.

The rise of antibiotic pollutants in water threatens ecosystems and human health. Iron-modified biochar (BC) exhibits adsorption properties offers a promising approach for effective environmental remediation. current study explored the potential iron-loaded synthesized from pine cones removal water. In this study, cones, sustainable renewable source, were used to produce iron-modified employed remove azithromycin, ciprofloxacin, their mixture aqueous solutions. Biochar was through pyrolysis modified by addition iron salts. analysis Fourier-transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), scanning electron microscopy (SEM) suggested crystalline structure rich minerals functional groups (O–H, C=O, C≡C) loaded with iron, having plate-like roughness distorted morphology along sharp edges corners. Antibiotic evaluated changing physical parameters, including dose, pH, temperature. maximum percentages obtained as 87.8%, 91.3%, 84%, respectively, at low Fe-modified higher Application kinetic models that antibiotics on is more inclined toward pseudo-second-order ( R 2 > 0.98) kinetics, indicating chemisorption nature process. findings highlight removing
