Measurements of Carcinogenic Air Pollutants in Seoul Metropolitan Subway Stations
초록
This paper reports an investigation of concentrations major carcinogenic indoor air pollutants for radon, formaldehyde, and asbestos in the 83 subway stations in the Seoul metropolitan area during November 1991~September 1992. Mean concentrations of indoor pollutants in Seoul subway stations surveyed were 0.23 ppb for formaldehyde, 1.12 pCi/l for radon, and 0.008 fiber/cc for asbestos. Mean formaldehyde concentrations in 83 subway stations were below the U.S. EPA formaldehyde standard (100 ppb), whereas mean concentrations of radon and asbestos in 2% and 22% of total sampled subway stations exceeded the U.S. radon (4 pCi/l) and asbestos (0.01 fiber/cc) standand, respectively. It is likely that possible sources for radon and asbestos are radon intrusion from the leaking underground water and construction materials, respectively.
