대전 3, 4 공단지역의 대기중 중금속의 농도 = Airborne Concentrations of Heavy Metals in Taejon 3rd and 4th Industrial Complexes

다국어 초록 (Multilingual Abstract)

This research centered on seasonal analysis for the concentration of heavy metals in 5 sites within Taejon 3rd and 4th industrial Complexes. Total suspended particulates were collected on glass microfibre filters (Whatman EPM 2000) by high volume air samplers. About 20 metal elements including 13 toxic ones were analyzed by ICP-MS and ICP-AES after the pretreatment of mixed acid extraction.
The following results were summarized from the research : 1) the concentrations of TSPs were 17.7∼219.6㎍/㎥ while the arithmetic mean concentration was 101.7㎍/㎥ ; 2) the arithmetic mean concentration of human carcinogen such as arsenic, hexavalent chromium and nickel subsulfide was 9.99, 6.68 and 6.13 ng/㎥ while that of probable human carcinogen such as beryllium, cadmium and lead was 0.12, 3.37, 97.65 ng/㎥, respectively.
