A receptor model application was performed by using a chemical mass balance (CMB) model to identify and apportion the specific source of airborne organic pollutants, particularly polynuclear aromatic hydrocarbons (PAHs). Source profiles of PAHs produced from the combustion of fossil fuels for CMB modeling were prepared by measuring them in emission gases. The emission sources which were examineed for the development of PAH source profiles are a coal-fired furnace using Yontan, a bunker-C iol heating boiler, and gasoline-and diesel engine automobiles. The ambient concentrations of PAHs were determined at four sites in Daejon city in 1991 with a seasonal variation. Wintertime air samples contained more extractable organic matter than summertime samples. The results of CMB modeling were various depending on the sampling sites and seasons, but the emission from bunker-C oil heating boliers was the predominant factor to affect local air quality throughout the year.

In order to comprehension of the behaviour of PAHs in air which is known as carcinogens and/or mutagens suspended Particulates in ambient air were collected by Anderson air sampler from 1992. 6 to 1993. 5 in Seoul. Ten species of PAHs( Phen, An, Fl, R, Py, BaAn, BaP, Chry, BeP, DiB(a, h)An, I123p) were analyzed to understand monthly variations of PAHs distribution of PAHs concentration according to particle size, and correlation between PAHs and independent charactierstics of PAHs The highest concentration of TSP was 155.58$\mu\textrm{g}$/㎥ in May and the lowest was 60$\mu\textrm{g}$/㎥ in August. Concentration of TSP was more affected by coarse particles in spring, otherwise which was more affected by fine particles in winter. According to results of anaylsis of samples that were collected by Anderson air sampler, concentration of PAHs was more high in winter than that in summer. In almost samples collected by Anderson air sampler, concentration of PAHs was more high in coarse particles than in fine particles, but BaP well known as carcinogenic matter had more high concentration in fine particles(56-97.5%) than that in coarse particles(2.5-46%). Correlation between concentrations of TSP and PAHs was more high in fine Particles than in coarse Particles. Both fine particles and coarse particles have negative correaltion with radiation.

최근 들어서 환경유해물질이 인체에 미치는 영향에 대한 관심이 커지고 있다. 특히 환경 중에 존재하는 발암성 물질에 대한 연구가 활발히 진행되면서 이들 물질이 인체에 미치는 위해성이 밝혀지고 있다. 다환방향족탄화수소(Polycyclic Aromatic Hydrocarbons, PAHs) 는 환경에 존재하는 중요한 발암물질이자 돌연변이 유도체이다. PAHs는 화석연료의 불완전 연소 등에 의해 발생되고, 대표적인 오염원으로는 석탄 연소, 자동차, 가정 난방 등이 있다. (중략)

최근의 급속한 화석연료의 소비 증가로 각종 유기오염물질들이 다량으로 배출되고 있다. 대도시나 석유화학 관련업체가 밀집된 공단지역의 공해 관리를 위해서는 이러한 유기오염물질들에 대한 기초 자료의 확보가 시급히 이루어져야 할 것으로. 보인다. 대기 중 미량 유기오염물질들은 주로 자동차, 산업체, 난방연료, 쓰레기 소각 등 인위적 요인에 의해서 발생(Westerholm et al., 1991)되고 있으며 이 중 PAHs는 대표적인 유기오염물질이다.(중략)

Atmospheric concentrations of polycyclic aromatic hydrocarbons (PAHs) were measured at the Chonbuk National University located in Jeonju, four times between June and November 2002, each time for five days. Twenty-four compounds including five alkyl PAHs and byphenyl were analyzed. Average total concentration of 24 PAHs was 85 $\pm$ 15 ng/$m^3$ and about 94% of PAHs existed in the gas phase. On an average, naphthalene accounted for about 30% of the total PAHs concentration. The gas/particle partitioning was not much varied during the measurement period. High molecular weight PAHs with five and six rings were primarily associated with fine particles less than 1 $\mu$m. Lower molecular weight PAHs were evenly distributed in fine and coarse particles so that their distribution was similar to that of TSP.

나프탈렌(Naphthalene)과 같은 다환방향족탄화수소류(Polycyclic aromatic hydrocarbons, PAHs)는 수계에 유입되어 해양생물들에게 영향을 미치게 된다. 나프탈렌은 유류속의 PAHs 내에서 함량이 가장 높으며, 독성이 강하다. 본 연구에서는 대조구(0 ${\mu}g/L$), 1000, 1800, 3200, 5600, 10000 ${\mu}g/L$의 6개 나프탈렌 농도구를 설정하고 넙치 치어에 대한 나프탈렌의 24시간 반수치사농도(24h-$LC_{50}$)을 구했으며, 아가미, 간, 신장, 근육내의 나프탈렌 농도를 분석하였다. 넙치 치어의 24h-$LC_{50}$은 Large 그룹에서 2410.76 ${\mu}g/L$, Small 그룹에서 2230.67 ${\mu}g/L$을 나타내었다. 각 조직에서의 나프탈렌 농도는 간 및 신장에서 아가미 및 근육보다 높았다.

Objectives: This study was carried out in order to estimate atmospheric polycyclic aromatic hydrocarbon (PAH) concentrations and sources using pine needles as a passive air sampler (PAS) in urban (Pyeongtaek), semirural (Anseong) and rural (Jincheon) sites. Methods: One-year-old pine needles were collected for analysis of their PAH concentrations ($C_{p,n}g/g$ dry) at the end of December. PAHs concentrations in the ambient air ($C_a$, $ng/m^3$) were calculated with a $Log(C_p/C_a)-LogK_{oa}$ correlational equation. Results: PAHs concentrations in ambient air ($C_a$) were high, in the order of urban ($114.03ng/m^3$), semirural ($105.17ng/m^3$) and rural ($61.91ng/m^3$) sites. However, distributions of PAH isomer concentrations were very similar. PAHs of which molecular weight is smaller than 228.30 (AcPy, Acp, Flu, Phen, Ant, Flt, Pyr, BaA, Chry) made up most of the PAHs in the ambient air (96.6-98.5%). Conclusion: At urban, semirural and rural sites, it was concluded that the main source of PAHs in the ambient air ratio of each PAH isomer concentration was cars, especially diesel vehicles.

Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous contaminants in coastal marine environment. PAHs enter estuarine and nearshore marine environment via several routes such as combustion of fossil fuels, domestic and industrial effluents and oil spills. In August of 1997, sediment and mussels (Mytilus edulis) were collected at 6 sites near Kori nuclear power plant in order to analyze the PAH content by HPLC with uv/vis detection. The concentrations of 15 PAH in sediment ranged from < 1 to 5,900 ppb ( mean 173.5$\pm$99.7 ppb), and in mussels, from < 0.5 to 4,125 ppb (mean 105$\pm$60.5 ppb). Compared with other studies world over, the concentrations of carcinogenic PAHs were relatively low in both sediment and mussels from the intertidal zone of Kori. This study presents preliminary data for the PAH levels in sediment and mussels from the intertidal zone of Kori, and the data will hopefully be utilized for the assessment of oil pollution in the Southeast East Sea, Korea (especially for the PAHs).

해수 내 유류계 방향족탄화수소인 BTEX(benzene, toluene, ethylbenzene, xylene)와 다환방향족탄화수소(polycyclic aromatic hydrocarbons: PAHs)를 동시에 분석할 수 있는 기술 개발을 위해 GC/MS에서 고체상미량추출법(solid phase microextraction: SPME)을 이용하여 최적의 분석기법을 정립하였다. SPME 기법은 전통의 분석 방법과 비교할 때 조작이 간단하고, 파이버를 재사용할 수 있고, 휴대하기 쉽고, 시료의 운반이나 저장하는 동안 오염을 최소화 할 수 있는 장점이 있다. 최적의 SPME 조건을 정립하기 위해 여러 변수 즉, SPME 수착제, 흡착 시간, 흡착 온도, 교반 속도, GC 탈착 시간들을 확인하였다. 다양한 SPME 수착제($100{\mu}m$ PDMS, $75{\mu}m$ CAR/PDMS, $65{\mu}m$ PDMS/DVB)를 이용하여 BTEX와 PAHs(분자량 78부터 202까지)를 동시에 분석한 결과 $65{\mu}m$ PDMS/DVB를 최적의 수착제로 선정하였다. 최적의 수착제로 $65{\mu}m$ PDMS/DVB 선정한 다음 순차적으로 다른 변수들을 확인하였다. 그 결과 BTEX와 PAHs 동시 분석하기 위한 최적의 SPMD 조건은 흡착시간 60분, 흡착온도 $50^{\circ}C$, 교반속도 750 rpm, GC 탈착시간 3분으로 결정되었다. 최적화한 HS-SPME-GC/MS 분석법을 이용하여 인공오염해수 내 유류계 방향족탄화수소 분석 결과 이전 연구 방법과 유사하였다. HP-SPME-GC/MS 분석법은 기존에 유기용매를 사용한 방법이 가졌던 단점과 제한점을 보완할 수 있으며, 해수 내 유류에 의한 BTEX 및 PAHs 분석에 효율적으로 적용할 수 있다.
