- Abstract
- Carbon dioxide and CH4, C6H6 and C7H8 fluxes from the soil cover of Case Passerini landfill site (Florence, Italy) were
measured using the accumulation and static closed chamber methods, respectively. Results show that the CH4/CO2, CH4/
C6H6 and CH4/C7H8 ratios of the flux values are relatively low when compared with those of the 'pristine' biogas produced by
degradation processes acting on the solid waste material disposed in the landfill. This suggests that when biogas transits
through the cover soil, CH4 is affected by degradation processes activated by oxidizing bacteria at higher extent than both
CO2 and mono-aromatics. Among the investigated hydrocarbons, C6H6 has shown the highest stability in a wide range of
redox conditions. Toluene behaviour only partially resembles that of C6H6, possibly because de-methylation processes require
less energy than that necessary for the degradation of C6H6, the latter likely occurring via benzoate at anaerobic conditions
and/or through various aerobic metabolic pathways at relatively shallow depth in the cover soil where free oxygen is present.
According to these considerations, aromatics are likely to play an important role in the environmental impact of biogas
released into the atmosphere from such anthropogenic emission sites, usually only ascribed to CO2 and CH4. In this regard,
flux measurements using accumulation and static closed chamber methods coupled with gas chromatography and gas chromatography-
mass spectrometry analysis may properly be used to obtain a dataset for the estimation of the amount of volatile
organic compounds dispersed from landfills (literal)
