2019, ChemosphereCitation Excerpt :This indicates that the biological removal of VOCs may primarily be carried out by the soil microcosm. Increased removal of formaldehyde by removing leaves of Chlorophytum elatum has previously been reported with an explanation that leaves covering the soil surface hindered diffusion of the pollutant into the soil for microbial degradation (Godish and Guindon, 1989). The leaves of H. helix partially covered the soil surface in this study and could potentially hinder the diffusion of the gasoline mixture into the soil.

2018, ChemosphereCitation Excerpt :Orwell et al. (2006) suggested that this was a result of toluene supporting a specific microbial population and inducing within that population the activity of the enzyme catechol 1,2 dioxygenase which is used for the biodegradation of both pollutants, however when toluene concentrations become limiting, m-xylene was then more effectively biodegraded. Numerous studies have noted the innate ability of plant growth substrates to adsorb VOCs (Godish and Guindon, 1989; Hörmann et al., 2017), and consequently substrates of different compositions have been trialled in experiments for their capacity to influence VOC removal. Aydogan and Montoya (2011) noted the substrate’s contribution to removal efficiency as their activated carbon substrate treatment demonstrated larger reductions in formaldehyde in comparison to expanded clay and growstone substrates, and concluded that substrates that have high adsorption capacities and provide sufficient microbial sites could lead to increased VOC removal.
