The combination of micron zero-valent iron (mZVI) and microorganisms is an effective method for trichloroethylene (TCE) degradation, but electron transfer efficiency needs improvement. A new chem-bio hybrid process using a composite material (S-ZVI@biochar) was developed, consisting sulfurized mZVI biochar as chemical remover, Shewanella oneidensis MR-1 dechlorinating bacteria (DB) biological agent TCE degradation. S-ZVI@biochar showed improved stability, biocompatibility, removal compared to ZVI S-ZVI. system DB + exhibited the highest at 96.5% after 30 days, which 3.7 times higher than that bare ZVI. study revealed enhanced dechlorination performance due efficiency, adjustment microbial community structure, recycling. constructed transport channels in system, improving overall capacity. This shows promise long-term anaerobic environments.

Chlorinated hydrocarbons are typical organic pollutants in contaminated sites, and microbial remediation technology has attracted more attention. To study the structural characteristics assembly mechanism of archaeal community chlorinated hydrocarbon-contaminated soil, unsaturated-zone soil within 2~10 m was collected. Based on high-throughput sequencing technology, analyzed, main drivers, environmental influencing factors, mechanisms were revealed. The results showed that hydrocarbon pollution altered structure. composition significantly correlated with trichloroethylene (r = 0.49, p 0.001), chloroform 0.60, pH 0.27, 0.036), sulfate 0.21, 0.032), total carbon 0.23, 0.041). Under stress, relative abundance Thermoplasmatota increased to 25.61%. Deterministic processes heavily polluted resulting reduced species richness, while positive collaboration among surviving 100%. These provide new insights into organization communities sites a basis for activities.

This study presents a novel approach for the simultaneous identification and quantification of extractable chlorinated organic carriers (COCs) from diverse materials, including textiles, foam leather. COCs, valued chemical synthesis, dye transfer solvents formulations. In this work, dichloromethane under ultrasonic conditions at 25 ºC 30 minutes was employed extraction COCs. Gass chromatography mass spectrometry (GC-MS) utilizing DB-5MS column facilitated separation detection target analytes. Selective ion monitoring (SIM) ionization mode with precursor daughter ions were utilized detection. Optimization parameters such as extractant type, method, time resulted in high recoveries ranging 95% to 105%. The calibration curve exhibited range 5 120 ng mL-1 regression values 0.996-0.998. method demonstrated excellent precision relative standard deviations (RSD) below 10% test specimens pure standards. Limits (LODs) 0.1 mL-1, indicating sensitivity. Application developed real successfully detected COCs concentrations 2.60 9.94 affirming its effectiveness environmental risk assessment.
