대기 중 Benzopyrene 및 중금속의 농도와 입경분포
허문영(Moon Young Heo),권창호(Chang Ho Kweon),유기선(Ki Seon Yu),최성규(Seong Kyu Choe),김경호(Kyeong Ho Kim),손동헌(Dong Hun Sohn) 대한약학회 1990 약학회지 Vol.34 No.1
Total suspended particulate (TSP) in the atmosphere was collected and size-fractionated by Andersen high volume air sampler for the past two years (Mar. 1987-Feb. 1989) in Seoul. The concentrations of several Polycyclic aromatic hydrocarbons and heavy metals were determined to investigate the atmospheric concentrations, seasonal variations and its relationship with the size distribution of suspended particulate matter. The arithmetic mean concentration of total suspended particulate was 229.48mcg/m3. The concentrations of heavy metals were 2971.94ng/m3 for Fe, 767.75ng/m3 for Zn, 765.80ng/m3 for Pb, 218.40ng/m3 for Cu, 129.91ng/m3 for Mn, respectively. And the concentration of PAHs were 3.23ng/m3 for benzo(a)pyrene, 2.71ng/m3 for benzo(k)fluoranthene, 4.53ng/m3 for benzo(ghi)perylene, respectively. The mass-size distribution of TSP was lowest in the particle size range 1.1-3.3mcm increased as the particle size increased or decreased. But PAHs, Pb and Zn abounded in particles below 2.0mcm, while Fe and Mn abouned in particles above 2.0mcm. TSP and its chemical compositions showed the seasonal variations. The concentrations of anthrophogenic origin like TSP, PAH and heavy metals in the fine particles were highest in winter and lowest in summer. PAH and Ph analyzed showed significant correlations with each other and with TSP concentration in fine particles, indicating that the particles in which they are contained have a similar behavior in the atmosphere.

마우스 골수 소핵 시험에 의한 디젤분진, HgCl_(2) 및 Pb(Ac)_2의 유전독성효과
허문영,최성규,유기선,손동헌 江原大學校 附設 環境硏究所 1989 環境硏究 Vol.6 No.-
The clastogenic effects of the diesel emission particle extrace(DEPE), mercuric chloride and lead acetate were examined by the mouse bone marrow micronucleus test. DEPE had a potent clastogenic effect by intraperitoneal injection with dose-response between 100 and 300mg/kg b.w.. Mercuric chloride and lead acetate also gave a clastogenic effects but mercuric chloride only had a dose-response between 1 and 3mg/kg b.w.. When DEPE was administrated with mercuric shloride or lead acetate, the frequency of micronucleated cells was slight but not significant incresase in comparision to a single treatment with DEPE alone.
