“…fuel combustion residues from vehicles or agricultural machinery. [26] Some mono-and sesquiterpenes were also present, but only in low amounts. On the other hand, in the treated soil gas phase, mono-and sesquiterpenes appeared in higher concentrations, trans-caryophyllene, β-myrcene, p-cymene, α-humulene and α-terpinolene being the most important compounds identified.…”

“…In particular, potentially harmful products such as alkylbenzenes, including styrene as well as chlorinated compounds, are frequent volatile organic molecules from composts. [42] CONCLUSION Solid Phase Microextraction, combined with GC-MS, is a simple and fast fractionation technique useful for the identification of volatile compounds in soils. This technique was highly responsive to the nature and transformations of organic inputs applied to the soil.…”

The complex molecular assemblages were analysed in the soil gas phase after applying pine forest wastes (PFW) or sugarbeet vinasses (SBV) for soil-borne crop pests management. For this purpose, solid-phase micro-extraction (SPME) and gas chromatography (GC) were used coupled with mass spectrometry (MS). The organic wastes were applied either to Calcic Entisol or Haplic Arenosol moistened at field capacity and soil was covered with polyethylene sheet for 28−30 days to retain the volatiles. The PFW-treated soil mainly released volatile terpene hydrocarbons (trans-caryophyllene, β-myrcene and p-cymene), with α-humulene and ethylbenzotriazole prevailing in the untreated soil. After SBV application mainly alkyl compounds and alkylbenzenes were released, whereas cyclohexanone, limonene, butanone, acetic acid, camphor and benzaldehyde occurred in the untreated soil. Compound assemblages also depended on the increasing water saturation in terms of soil depth, with sulphur compounds prevailing in deep horizons. Our results showed that SPME can be directly applied to soils to provide valuable information on volatile products from organic amendments.

“…In their work, they studied the effects of column temperature, gas residence time, and inlet concentrations on the removal of these compounds in a compost‐packed biofilter. The study found out that the highest removal was for toluene, and the lowest removal was for CF . Furthermore, in a study of co‐metabolism of THMs (including CF and DCBM) conducted with a nitrifying biofilm in biofiltration by Wahman et al obtained a CF removal ranging between 13% and 43%.…”

“…There are a few research studies in the literature that reported the effective use of the biofiltration for the treatment of a mixture of CF and other VOC gasses. 29,30 Balasubramanian et al 29 studied how the elimination capacity (EC) and removal efficiency (RE) of biofiltration for treating a complex mixture of VOCs are affected by the inlet loading rate (LR) and empty bed residence time (EBRT). Their BTF was operated at both steady and transient conditions, for different inlet LRs, empty bed residence time, and inlet CF concentrations.…”

In this study, the biodegradation of a mixture of two trihalomethane (THM) compounds, chloroform (CF) and dichlorobromomethane (DCBM), was evaluated using two laboratory‐scale biotrickling filters (BTFs). The two BTFs, hereby designated as “BTF‐A” and “BTF‐B,” were run parallel and used ethanol as co‐metabolite at different loading rates (LRs), and a lipopeptide‐type biosurfactant that was generated by the gram‐positive bacteria, Surfactin, respectively. The results using BTF‐A showed that adding ethanol at a higher rate of 4.59 g/(m3 h) resulted in removal efficiencies of 85% and 87% for CF and DCBM, respectively. Conversely, for the same LR, the use of Surfactin without ethanol (BTF‐B) showed comparable removal efficiencies of 85% and 80% for CF and DCBM, respectively. The maximum rate constant for CF and DCBM for the BTF‐A was 0.00203 s−1 and 0.0022 s−1, respectively. For the same THMs LR, similar reaction rate constants resulted for the BTF‐B. Further studies were conducted to investigate and understand the microbial diversity within both BTFs. The result indicated that for BTF with co‐metabolite, Fusarium sp. was the most dominant fungi over 98% followed by F. Solani with less than 2%. F. oxysporum and Fusarium sp. were instead the dominant fungi for the BTF with Surfactin. Before introducing the Surfactin into the BTF, the batch experiment was conducted to evaluate the effectiveness of synthetic surfactant as compared to a biosurfactant (Surfactin). In this regard, vials with Surfactin showed better performance than vials with Tomadol 25‐7 (synthetic surfactant).

“…However, up to now, most researches on biofiltration have dealt with only single or binary gas, which seems to be impractical for real industrial application. This is because most of the emission sources contain multiple contaminants including sulfur and nitrogen compounds as well as VOCs, but limited to single or binary contaminants [16,17,20,[33][34][35][36][37][38]. Cox and Deshusses [20] investigated the treatment of the binary toluene-H 2 S containing waste air using bio-trickling beds.…”

Simultaneous removal of ternary gases of NH 3 , H 2 S and toluene in a contaminated air stream was investigated over 185 days in a biofilter packed with cork as microbial support. Multi-microorganisms including Nitrosomonas and Nitrobactor for nitrogen removal, Thiobacillus thioparus (ATCC 23645) for H 2 S removal and Pseudomonas aeruginosa (ATCC 15692), Pseudomonas putida (ATCC 17484) and Pseudomonas putida (ATCC 23973) for toluene removal were used simultaneously. The empty bed residence time (EBRT) was 40-120 seconds and the inlet feed concentration was 50-180 ppmv for NH 3 , 30-160 ppmv for H 2 S and 40-130 ppmv for toluene, respectively. The observed removal efficiency was 45-100% for NH 3 , 96-100% for H 2 S, and 10-99% for toluene, respectively. Maximum elimination capacity was 5.5 g/m 3 /hr for NH 3 , >20.4 g/m 3 /hr for H 2 S and 4.5 g/m 3 /hr for toluene, respectively. During longterm operation, the removal efficiency of toluene gradually decreased, mainly due to depositions of elemental sulfur and ammonium sulfate on the cork surface. The results of microbial analysis showed that nearly the same population density was observed on the surfaces of cork chips collected at each sampling point. Kinetic model analyses showed that there were no particular evidences of interactions or inhibitions among the microorganisms.
