Investigation on the Emission and Diffusion of Hydrogen Sulfide during Landfill Operations: A Case Study in Shenzhen

This study investigated the emission and diffusion of hydrogen sulfide (H2S), as one odorous gases generated from landfills, in a municipal solid waste landfill south Chinese city. To this end, flux H2S emissions working area its surrounding were measured. The was simulated at different wind speeds, directions, bare areas landfill, heights angles between direction long side area. results indicated that concentration around monitoring point ranged 0 to 60 µg/m3, data consistent with measured results. At uniform direction, pollution range narrow. Furthermore, an increase height dump, decreased but rose Notably, when angle 0°, largely spread along extension cord When increased 90°, influence extended significantly. site should be regulated based on monitored reduce effect harmful gas living environment, health staff nearby residents.
