Abstract

Gaseous hydrocarbons were analyzed for interstitial water and soil gas of peat samples from Tateyama, Midagahara, Japan in order to clarify the relationship between the redox coditions and light hydrocarbons of terrestrial origin. Methane, C₂-C₄ alkanes and C₂-C₃ alkenes were recognized nevertheless high redox conditions, in which dissolved oxygen was saturated with the atmosphere. However, light hydrocarbon contents, particularly methane, are extremely low in comparison with other peat land such as Oze and Miyadoko moors. On the basis of the abundance ratios of alkanes and ethylene relative to methane, ethane/ ethylene, and i-butane/n-butane, it is suggested that where methane-bearing interstitial water discharged into aerobic environments microbial methane oxidation may occurred.
