The efficiency of polycyclic aromatic hydrocarbon (PAH) removal by indigenous microorganisms is often suboptimal, resulting in constraints on its practical application. To enhance the degradation benzo[a]pyrene (B[a]P) contaminated soil, an effective microbial fermented product (EMF) was employed as a biostimulant. Our findings demonstrated that when 1‱ or 1‰ (w/w) EMF applied to B[a]P-contaminated soil for 21 days, biodegradation rates B[a]P were 59.37% and 100%, respectively, which much higher than natural attenuation (18.79%). abundance 16S rDNA PAH-RHDα GP genes both significantly increased due EMF. Soil enzymatic activities also affected, different degrees, addition diversity, composition, functionality community changed varying degrees. These results suggest use may hold promise remediation PAH-contaminated soils.

Land Degradation and Development, Journal Year: 2025, Volume and Issue: unknown

Published: April 23, 2025

ABSTRACT Carbendazim, a commonly used fungicide, was identified as contributor to soil degradation. Despite the extensive use of carbendazim, degradation mechanisms and removal process carbendazim in environment were not yet fully understood. A deeper understanding pathways considered essential for developing effective strategies mitigate long‐term environmental impacts. The using ozone water environments investigated with simulation experiments exposure soil, efficiency also explored under different conditions study. results showed that ozone‐induced proceeded three stages: rapid removal, slow equilibrium. In water, directly reacted generating hydroxyl radicals (˙OH), which oxidized into intermediates, including 2‐aminobenzimidazole, 2‐hydroxybenzimidazole, 2‐benzimidazolone, o‐phenylenediamine. intermediates eventually degraded nontoxic byproducts such carbon dioxide water. treatment enhanced by catalyzing production active substances, (˙OH) hydrogen peroxide (H 2 O ). Increasing aeration frequency four times daily significantly improved reaching peak rate 70.4% after 21 days soil. findings this study clarified theoretical remediation, highlighted critical role process, established scientific foundation remediation targeting carbendazim‐induced contamination.
