一部 地下空間 粉塵의 突然變異原性 調査硏究 = Study on Mutagenicity of the Airborne Particles in Underground Construction

다국어 초록 (Multilingual Abstract)

This paper is to examine the mutagenic activity of the airborne particles at the sites of shopping center, parking lots, subway, tunnel in underground construction and atomsphe from May to December, 1988. For this examination, Ames method using Salmanella typhimurium was adopted.
The results are as follows :
1. At the sampling sites of shopping center, parking lots, subway, tunnel and atmospher, the average concentrations of total suspended particles were 559.0u g /㎥, 4,475.0㎥/㎥ and 143.0ug /㎥, 374.5㎍/㎥, 442.0㎍/㎥, 4,475㎍/㎥ and 143.0㎍/㎥ respectively.
2. As for benzene and methanol extracts the concentrations were shopping center 21.6㎍/㎥ parking lots 53.4㎍/㎥, subway 46㎍/㎥ tunnel 372.0㎍/㎥ and atmospher is 165㎍/㎥
3. The average revertant colonies of the benzene-ethanol extract of 250㎍ per plate on TA98 were shopping center 205/plate, parking lots 269/plate, subway 288/plate tunnel 407/plate, and atomsphere 549/plate.
4. The average revertant colonies of the airborne particles in 1 ㎥ air volume on TA98 were shopping center 20.4/㎥, parking lots 58.3/㎥, subway 55.0/㎥, tunnel 763.2/㎥, and atmospher 54.5/㎥.
5. Mutagenic activity of air at the sampling site of tunnel was higher than those of other sampling sites.
