“…Despite the limitations of bioaugmentation (Megharaj et al 2011;Gao et al 2014;Shahi et al 2016), it can be used to remediate sites polluted with recalcitrant pollutants (Philp and Atlas 2005). Nevertheless, biostimulation is a more cost-effective and practical approach to bioremediation (Simpanen et al 2016). Remediation by enhanced natural attenuation (RENA), which involves improving nutrient, aeration, and moisture content is a good example of land farming in situ bioremediation approach, which have recorded many successes towards pollutant removal (Okukoya and Lambert 2015).…”

“…Further, pollutant inhomogeneity coupled with changes in climate contributes to variability in results obtained during fieldscale bioremediation (Garg et al 2016). This makes it difficult to directly compare the results of lab-scale with that of field-scale bioremediation studies (Simpanen et al 2016). This study was carried out to determine bacterial community shift and the efficacy of RENA towards pollutant removal during field-scale bioremediation project at Okodia-Rumuekpe, Ikarama Community, Yenagoa, Bayelsa State, Nigeria.…”

Acute and chronic pollution of environments with crude oil does not bode well for biota living within the vicinity of polluted environments. This is due to environmental and public health concerns on the negative impact of crude oil pollution on living organisms. Enhancing microbial activities by adding nutrients and other amendments had proved effective in pollutant removal during bioremediation. This study was carried out to determine how microbial group respond during remediation by enhanced natural attenuation (RENA) during a field-scale bioremediation. Crude oil-polluted soil samples were collected (before, during, and after remediation) from a site undergoing remediation by enhanced natural attenuation (RENA) at Ikarama Community, Bayelsa State, Nigeria, and were analyzed for total petroleum hydrocarbon (TPH), polyaromatic hydrocarbon (PAH), and a shift in microbial community. The gas chromatography-flame ionization detector (GC-FID) results showed that the pollutant concentrations (TPH and PAH) reduced by 98 and 85%, respectively, after the remediation. Culturable hydrocarbon utilizing bacteria (CHUB) was highest (8.3 9 10 4 cfu/g) for sample collected during the remediation studies, whilst sample collected after remediation had low CHUB (6

“…Typical factors that limit natural soil degradation capacity are the lack of nutrients (especially N), soil anoxia, low temperature, insufficient soil moisture, or unsuitable pH (Simpanen et al 2016; Kauppi et al 2011; Suni et al 2007; Vallejo et al 2001; Margesin 2000; Romantschuk et al 2000). When the soil C:N ratio was balanced by N amendments in the present study, bacterial growth increased but also the community structure changed.…”

The use of in situ techniques in soil remediation is still rare in Finland and most other European countries due to the uncertainty of the effectiveness of the techniques especially in cold regions and also due to their potential side effects on the environment. In this study, we compared the biostimulation, chemical oxidation, and natural attenuation treatments in natural conditions and pilot scale during a 16-month experiment. A real fuel spill accident was used as a model for experiment setup and soil contamination. We found that biostimulation significantly decreased the contaminant leachate into the water, including also the non-aqueous phase liquid (NAPL). The total NAPL leachate was 19 % lower in the biostimulation treatment that in the untreated soil and 34 % lower in the biostimulation than oxidation treatment. Soil bacterial growth and community changes were first observed due to the increased carbon content via oil amendment and later due to the enhanced nutrient content via biostimulation. Overall, the most effective treatment for fresh contaminated soil was biostimulation, which enhanced the biodegradation of easily available oil in the mobile phase and consequently reduced contaminant leakage through the soil. The chemical oxidation did not enhance soil cleanup and resulted in the mobilization of contaminants. Our results suggest that biostimulation can decrease or even prevent oil migration in recently contaminated areas and can thus be considered as a potentially safe in situ treatment also in groundwater areas.Electronic supplementary materialThe online version of this article (doi:10.1007/s11356-016-7606-0) contains supplementary material, which is available to authorized users.

“…11,12 The tightly soilsorbed cationic surfactants facilitate the transport of solubilized PAHs to immobile sorbed surfactants, favouring the environmental remediation of PAHs at the localized scale. 13 The mechanism of PAH adsorption on cationic surfactants is similar to the distribution role of SOM, and the distribution intensity of cationic surfactants is stronger than that of natural OM by 10-30 times. 14 Studies have reported that cetyltrimethyl ammonium bromide (CTMAB) and dodecylpyridinium bromide (DDPB) effectively inhibited the solid-vapor volatilization of PAHs and enhanced the soil retention of PAHs (p < 0.05) under aerobic conditions.…”
