“…thermal desorption (ITRC 2005;Javorska et al 2009;Osgerby 2006). Studies have shown that ozone effectively removed polycyclic aromatic hydrocarbons (PAHs) (Rivas 2006), polychlorinated biphenyls (Javorska et al 2009), diesel fuel (Yu et al 2007), and residual oil following long-term biodegradation (Liang et al 2009). Ozonation is also an effective pre-treatment that enhances the subsequent biodegradation step by reducing the toxicity of the contaminants, producing more biodegradable intermediates, and/or improving the bioavailability of the parent compounds (Goi and Trapido 2004;Liang et al 2009;Nam and Kukor 2000;Sutton et al 2011).…”

“…Added as a gas, ozone can diffuse into soil aggregates. Furthermore, soils can be reused after ozonation (Javorská et al, 2009;Russo et al, 2012), as ozone reverts to oxygen (O 2 ) within a short period of time. This contrasts with other gas-phase oxidants (e.g.…”

“…Combining ozonation and bioremediation has already shown a high efficiency for accelerating the biodegradation of a range of other recalcitrant organic contaminants in soil (e.g. PAHs, substituted phenolics) (Adams et al, 1997;Bijan and Mohseni, 2005;Javorská et al, 2009;O'Mahony et al, 2006;Russo et al, 2012;Zeng et al, 2000).…”

The molecular complexity and the low solubility of petroleum hydrocarbon residuals in weathered soil hinder bioremediation as a clean-up strategy. Pretreatment with advanced oxidation, such as with ozone gas (O 3 ), is a means to transform recalcitrant organics to more biodegradable forms. The efficacy of gas-phase ozone for enhancing the biodegradability of heavy residual petroleum hydrocarbons in weathered soil was tested. Ozonating soil containing ∼1% (w/w) residual petroleum hydrocarbons with a dose of 6 kg ozone/kg initial total petroleum hydrocarbons (TPHs) achieved nearly 50% TPH reduction, simultaneous with a >20-fold increase in soluble chemical oxygen demand, but with a ≤12% loss of total organic carbon. TPH molecules were converted to partly oxidised products, ten of which were identified as n-monocarboxylic acids, which were readily biodegraded, and ozonation resulted in a fourfold increase in 5-d biochemical oxygen demand (BOD 5 ). BOD 5 results after ozonation were the same with or without a microbial seed, which suggests that bioaugmentation is likely not necessary after ozonation. Deoxyribonucleic acid sequencing over the time course of the BOD 5 tests showed increased diversity and changes in predominant genera, both of which underscore that ozonation made the heavy hydrocarbons readily biodegradable for soil bacteria.

The objective of this study was to investigate the rhizosphere effect of rape plants on polychlorinated biphenyls (PCB) dissipation in soils spiked with seven indicator congeners. Depletion of PCB in the rhizosphere was significantly higher in the soil with lower organic matter content. While in the Chernozem soil, 87% of PCB related to bulk soil were found in the 1st mm from roots, only 62%-69% were found in the Fluvisol soil with no significant influence of increased initial PCB concentration. Further from the roots, the concentration of lower chlorinated congeners decreased, which indicates their greater biodegradation in comparison with more chlorinated ones.
