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.

Differentiated effects and mechanisms of N-, P-, S-, and Fe-modified biochar materials for remediating Cd- and Pb-contaminated calcareous soil

Ecotoxicology and Environmental Safety, Год журнала: 2025, Номер 289, С. 117661 - 117661

Опубликована: Янв. 1, 2025

To investigate the remediation effects of various modified biochar materials derived from different impregnation agents on Cd- and Pb-contaminated calcareous soil, nitrogen (N-), phosphorus (P-), sulfur (S-), iron (Fe-) (NBC, PBC, SBC, FBC) were fabricated through impregnation-pyrolysis method employed to immobilize Pb Cd in soil. The characterization results showed that NBC exhibited an uneven pore size distribution increased aromaticity, while PBC SBC had pH ash content. Pot experiments demonstrated significantly soil immobilization plant uptake Pb. With regard pH, FBC caused a notable decrease both rhizosphere non-rhizosphere areas, other increase. NBC, effectively immobilized reduced their accumulation Chinese cabbage by 34.4 %-58.9 % for 9.2 %-53.1 Pb, with having best effect, attributed complexation, precipitation, adsorption. However, strong acidity poor ability, which available concentrations Additionally, promoted growth, enzyme activity, tolerance cabbage. Overall, identified as most effective stabilizing reducing heavy metal cabbage, boosting activity.

Antibiotics are identified as an emerging contaminant due to their persistence in the environment. Antibiotics, accumulation freshwater sources and wastewater have become a pollutant of concern. Every year million tons these contaminants discharged into water bodies. Through, feces urine humans animals, antibiotics metabolites enter Aquatic ecosystems exposed persistent pollutants they escape treatment process. Excessive usage has resulted generation antibiotic-resistant genes bacteria To maintain vitality environment, it becomes imperative mitigate toxic metabolites. avoid adverse consequences on non-target organisms, removal from environment is vital. Various remediation methods such conventional including ion exchange, precipitation used for degradation, however, efficacy traditional limited production sludge high cost maintenance. Biological bioremediation phytoremediation sustainable strategies eradicate antibiotics, hence widely. There many reviews antibiotic using microbes antibiotics. But not all can be remediated microorganisms, so there need more recent strategies. In present review, web-based search literature published between 2010 2022 carried out. Previous studies reported that living organisms like bacteria, fungi, algae, plants could utilized degradation degraded may get affected by factors inoculum size, microbial strain, culture conditions. Therefore, techniques use fuel cells, biochar, sawdust possible For elimination recalcitrant combined processes seem efficient permanent solution bypassing toxicity

Engineered biochar improves nitrogen use efficiency via stabilizing soil water-stable macroaggregates and enhancing nitrogen transformation

Biochar, Год журнала: 2023, Номер 5(1)

Опубликована: Сен. 1, 2023

Abstract The use of inorganic nitrogen (N) fertilizers has increased drastically to meet the food requirements world's growing population. However, excessive chemical fertilizer caused a series soil and environmental problems, such as hardening, lower efficiency (NUE), nitrate pollution water sources, nitrous oxide emissions, etc. In this review, we aimed elaborate discuss role engineered biochar in inducing stability water-stable macroaggregates, improving N transformation, utilization address current uncertainties loss maintaining quality. Firstly, elucidated characteristics quality work multifunctional player ecosystem promote resource utilization, conservation, preservation. Secondly, discussed how modulates macroaggregates transformation enhance plant response under various toxic or deficient conditions soil. Thirdly, biological fixation, mediating nirK , nirS nosZ genes conversion 2 O decreasing denitrification emission was reviewed. Altogether, suggest that amendment can regulate reduce input, improve metabolism, finally, NUE crop growth. To best our knowledge, is first time evaluate combined interactions "engineered × growth,” providing advantages over increasing productivity separately with aim enhancing together on sustainable basis.
