New atmospheric environment research from Dongeui University outlined

  2008 AUG 18 - (VerticalNews.com) -- According to recent research from South Korea, "In this study, the environmental behavior of reduced sulfur compounds (RSCs: H2S, DMS, CS2, DMDS, and CH3SH) was investigated in an area influenced by strong anthropogenic processes based on a numerical modeling approach. The RSC emission concentrations were measured from multiple locations around the Ban-Wall industrial complex (BWIC) in the city of An San (AS), Korea, during a series of field campaigns held between August 2004 and September 2005."

  "These emissions were then used as input for a CALPUFF dispersion model with the 34 dominant chemical reactions for RSCs. The impact of RSC emission on SO2 concentrations was assessed further in the study areas. The model study indicated the possibility that RSCs emitted in and around the BWIC can exert a direct impact on the ambient S02 concentration levels in its surrounding areas with the most prominent effect observed during summer. Our prediction indicated that a significant fraction of SO2 was produced photochemically in and around the BWIC during the summer (about 30% of total SO2 concentrations) and fall events (similar to 20%). These photochemical productions of SO2 were mainly ascribable to H2S (similar to 60% of total contributions) and DMDS (similar to 25%) out of all five target RSCs," wrote S.K. Song and colleagues, Dongeui University.

  The researchers concluded: "Meteorological contribution (dispersion) to S02 concentration level was also highest during summer."

  Song and colleagues published their study in Atmospheric Environment (Dispersion and photochemical oxidation of reduced sulfur compounds in and around a large industrial complex in Korea. Atmospheric Environment, 2008;42(18):4269-4279).
