울산만 내 퇴적물에 대하여 다이옥신/퓨란류(polychlorinated dibenzo-p-dioxins/dibenzofurans, PCDD/Fs)와 다이옥신류 피씨비(dioxin-like polychlorinated biphenyls, DL-PCBs), PBDEs(polybrominated diphenyl ethers)의 잔류수준을 조사하고 분포를 평가하였다. 33개 정점에서 채취한 퇴적물 중 PCDD/Fs, DL-PCBs, PBDEs는 각각 0.11~4.86(평균${\pm}$표준편차, $1.81{\pm}1.04$) pg $WHO_{2005}$-TEQ $g^{-1}$ 건중량(dw), 0.06~44.2($4.02{\pm}7.99$) pg $WHO_{2005}$-TEQ $g^{-1}$ dw, 2.81~63.8($19.4{\pm}13.9$) ng $g^{-1}$ dw 수준으로 검출되었다. 총 다이옥신류(PCDD/Fs+DL-PCBs)에 대하여 DL-PCBs가 약 88%로 PCDD/Fs에 비해 높은 기여율을 나타내었다. 또한, 울산만 내부에 위치한 정점의 퇴적물은 외부 정점에 비해 높은 농도수준을 보였다 (p<0.05). 총 다이옥신류 중 PCDD/Fs는 고염소의 DD/Fs에서 높은 기여율을 차지하였으며, 이성질체의 분포패턴은 연소공정의 영향이 큰 공업지역 퇴적물의 특성을 나타내었다. DL-PCBs는 PCB77, -105, -118가 주요 이성질체로써, 상업용 PCB 제품과 분포특성이 유사하게 나타났다. 또한, 퇴적물 내 PBDEs 분포에서 BDE209가 주요 이성질체로 나타났으며, 이는 상업용 deca-BDE 제품의 사용량에 의한 영향으로 판단된다.

고분해능 가스크로마토그래프/고분해능 질량분석기를 이용하여 시화공단 지역 근로자와 일반주민의 혈액에서 다이옥신류를 분석하였다. 평균 다이옥신류의 농도는 근로자가 일반주민보다 높았다. 근로자와 일반주민의 평균 다이옥신 TEQ 농도는 각각 40.3 pg I-TEQ/g lipid, 16.6 pg I-TEQ/g lipid였고, 전체 PCBs 농도는 각각 174.1 ng/g lipid, 151.0 ng/g lipid였다. 주성분분석을 한 결과, 근로자와 일반주민의 다이옥신 이성질체 분포는 구별되었지만, 모두 식품류에서의 분포와 유사하였다. 각 개인의 일일 다이옥신 섭취량을 계산했을 때 40%만이 WHO에서 제시한 1-4 pg I-TEQs/kg bw/day의 허용범주를 만족하였다.

Objectives : In this study, the exposure status of the hazardous substances from incinerators, such as polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs), were studied , and the relationship between the exposure of these hazardous substances and their heath effects on the workers and residents near municipal solid waste (MSW) incinerators and an industrial incinerator investigated. Methods : Between July 2001 and Jure 2002, 13 workers at two MSW incinerators, 16 residents from the area around the two MSW incinerators, 6 residents from the control area, and further 10 residents near an industrial incinerator, estimated to emit higher levels of hazardous substances, were interviewed. Information, including sociodemographic information, personal habits, and work history, detailed gynecologic and other medical history were collected through interviews. Blood samples were also collected from 45 subjects, and analyzed for PCDD/DFs, by high resolution gas chromatography -high resolution mass spectrometry, using the US EPA 1613 method. In addition to the questionnaire survey, urinary concentrations of 8-hydroxydeoxyguanosine (8-OH-dG) and malondialdehyde (MDA) were measured as oxidative injury biomarkers. The urinary concentrations of 8-OH-dG were determined by in vitro ELISA, and the MDA by HPLC, using u adduct with thiobarbituric acid. Results : The PCDD/DFs concentrations in the residents near the industrial incinerator were higher than those in the controls, workers and residents near the MSW incinerators. The average TEQ (Toxic Equivalencies) concentrations of the PCDD/DFs in residents near the industrial incinerator were 53.4pg I-TEQs/g lipid. The estimated daily intakes were within the tolerable daily intake range (1-4 pg I-TEQ/Kg bw/day) suggested by WHO (1997) in only 30% to the people near the industrial incinerator. Animal studies have already shown that even a low body border of PCDD/DFs, such as 10 ng TEQ/kg bw, can cause oxidative damage in laboratory animals. Our study also showed that the same body burden of PCDD/DFs can cause oxidative damage to humans. Conclusions : The exposures to PCDD/DFs and the oxidative stress of residents near the industrial incinerator, were higher than those in the controls, workers and residents near the MSW incinerators. Proper protection strategies against these hazardous chemicals are needed. Because a lower body burden of PCDD/Fs, such as 10ng TEQ/kg bw, can cause oxidative damage, the tolerable daily intake range should be restrictedly limited to 1pg I-TEQ/kg bw/day.
