Frontiers in Microbiology, Год журнала: 2020, Номер 11

Опубликована: Ноя. 5, 2020

Polycyclic aromatic hydrocarbons (PAHs) are wide-spread across the globe, mainly due to long-term anthropogenic sources of pollution. The inherent properties PAHs such as hetero-cyclic ring structures, hydrophobicity and thermostability have made them recalcitrant highly persistent in environment. PAH pollutants been determined be toxic, mutagenic, carcinogenic, teratogenic immunotoxicogenic various life forms. Therefore, this review discusses primary emissions, exposure routes their toxic effects on humans, particular. This briefly summarizes physical chemical remediation approaches membrane filtration, soil washing, adsorption, electrokinetic, thermal, oxidation photocatalytic treatments. provides a detailed systematic compilation eco-friendly biological treatment solutions for microbial using bacteria, archaea, fungi, algae co-cultures. In situ ex-situ treatments land farming, biostimulation, bioaugmentation, phytoremediation, bioreactor vermiremediation discussed detail summary factors affecting limiting bioremediation also discussed. An overview newly emerging technologies employing multi-process combinatorial newer concepts generation value-added by products during is highlighted review.

Integration of nanoscale zero-valent iron and functional anaerobic bacteria for groundwater remediation: A review

Environment International, Год журнала: 2019, Номер 124, С. 265 - 277

Опубликована: Янв. 16, 2019

The technology of integrating nanoscale zero-valent iron (nZVI) and functional anaerobic bacteria has broad prospects for groundwater remediation. This review focuses on the interactions between nZVI three kinds bacteria: organohalide-respiring (OHRB), sulfate reducing (SRB) (IRB), which are commonly used in bioremediation. coupling effects contaminant removal integrated system summarized. Generally, could create a suitable living condition growth activity bacteria. OHRB SRB synergistically degrade organic halides remove heavy metals with nZVI, IRB reactive passivated by (hydr)oxides surface nZVI. Moreover, roles these degradation mechanisms illustrated. In addition, this also discusses main factors influencing efficiency contaminants treatment system, including species dosage, inorganic ions, matters, pH, type pollutants, temperature, carbon/energy sources, etc. Among factors, dosage play fundamental role due to potential cytotoxicity might exert negative impact performance system. Lastly, future research needs proposed better understand effectively apply it
