Mechanisms of adsorption and functionalization of biochar for pesticides: A review

Ecotoxicology and Environmental Safety, Journal Year: 2024, Volume and Issue: 272, P. 116019 - 116019

Published: Jan. 30, 2024

Agricultural production relies heavily on pesticides. However, factors like inefficient application, pesticide resistance, and environmental conditions reduce their effective utilization in agriculture. Subsequently, pesticides transfer into the soil, adversely affecting its physicochemical properties, microbial populations, enzyme activities. Different interacting can lead to combined toxicity, posing risks non-target organisms, biodiversity, organism-environment interactions. Pesticide exposure may cause both acute chronic effects human health. Biochar, with high specific surface area porosity, offers numerous adsorption sites. Its stability, eco-friendliness, superior capabilities render it an excellent choice. As a versatile material, biochar finds use agriculture, management, industry, energy, medicine. Added helps absorb or degrade contaminated areas, enhancing soil activity. Current research primarily focuses produced via direct pyrolysis for adsorption. Studies functionalized this purpose are relatively scarce. This review examines biochar's absorption characteristics, formation mechanisms, impact, delves functionalization methods, prospects limitations.

Plant cultivation can influence the immobilization of heavy metals in soil. However, roles soil amendments and microorganisms crop-based phytoremediation require further exploration. In this study, we evaluated impact Zea mays L. cultivation, biochar application, arbuscular mycorrhizal fungi (AMF) inoculation on lead (Pb) immobilization. Our results indicated that addition resulted a significant, 42.00%, reduction AMF colonization. inoculation, all contributed to enhanced Pb immobilization, as evidenced by decreased levels diethylenetriaminepentaacetic acid- CaCl2-extractable Furthermore, subjected plant with displayed reduced concentrations bioavailable Pb. Biochar altered distribution fractions soil, transforming acid-soluble form into relatively inert reducible oxidizable forms. Additionally, biochar, AMF, their combined use promoted maize growth parameters, including height, stem diameter, shoot root biomass, phosphorus uptake, while simultaneously reducing concentration. These findings suggest synergistic effect phytostabilization. summary, despite adverse growth, cultivating concurrent emerges recommended effective strategy for phytoremediation.IMPORTANCEHeavy metal contamination is pressing environmental issue, has emerged sustainable approach mitigating problem. This study sheds light potential enhance contaminated The demonstrate during significantly improve offering promising practices. research contributes valuable insights field its address pollution agricultural soils.

Machine learning and computational chemistry to improve biochar fertilizers: a review

Environmental Chemistry Letters, Journal Year: 2023, Volume and Issue: 21(6), P. 3159 - 3244

Published: Aug. 17, 2023

Abstract Traditional fertilizers are highly inefficient, with a major loss of nutrients and associated pollution. Alternatively, biochar loaded phosphorous is sustainable fertilizer that improves soil structure, stores carbon in soils, provides plant the long run, yet most biochars not optimal because mechanisms ruling properties poorly known. This issue can be solved by recent developments machine learning computational chemistry. Here we review phosphorus-loaded emphasis on chemistry, learning, organic acids, drawbacks classical fertilizers, production, phosphorus loading, release. Modeling techniques allow for deciphering influence individual variables biochar, employing various supervised models tailored to different types. Computational chemistry knowledge factors control binding, e.g., type compound, constituents, mineral surfaces, binding motifs, water, solution pH, redox potential. Phosphorus release from controlled coexisting anions, adsorbent dosage, initial concentration, temperature. Pyrolysis temperatures below 600 °C enhance functional group retention, while 450 increase plant-available phosphorus. Lower pH values promote release, higher hinder it. Physical modifications, such as increasing surface area pore volume, maximize adsorption capacity biochar. Furthermore, acid affects low molecular weight acids being advantageous utilization. Lastly, biochar-based 2–4 times slower than conventional fertilizers.
