Hydrogen sulfide flux measurements from construction and demolition debris (C&D) landfills

摘要

Hydrogen sulfide (H_2S) has been identified as a principal odorous component of gaseous emissions from construction and demolition debris (C&D) landfills. Although several studies have reported the ambient concentrations of H_2S near C&D landfills, few studies have quantified emission rates of H_2S. One of the most widely used techniques for measuring surface gas emission rates from landfills is the flux chamber method. Flux measurements using the flux chamber were performed at five different C&D landfills from April to August, 2003. The flux rates of H2S measured in this research were between 0.192 and 1.76 mg/(m~2-d).
