石化工業區附近半揮發性有機物與戴奧辛衍生物之比較研究
A Comparative Study for Between Semi-Volatile Organic compounds (SVOCs ) and Dioxin-like Contaminants Near a Petroleum Industrial Park
摘要
戴奧辛類污染物已被廣泛研究，由於其急性毒性和對人體健康的負面影響。這些化合物的來源主要是人類活動，包括工業和熱處理過程所產生。研究以石化工業區附近魚塘中監測底泥與魚體影響情況，了解底泥與魚體中的累積性及多氯二聯苯戴奧辛/呋喃（Polychlorinated Dibenzo-p-Dioxin/Furans，PCDD/Fs）生成機制，本研究目的分析了石化工業區附近地區底泥與魚體中PCDD/Fs、半揮發性有機物(Semi-Volatile Organic Compounds，SVOCs)、多環芳香烴化合物(Polycyclic Aromatic Hydrocarbons，PAHs)的污染毒性當量和地區概況，底泥樣品毒性當量高於魚體。從魚塘中的底泥中PCDD/ Fs總毒性當量介於0.8 - 0.3 pg WHO-TEQ/g間，魚體則介於0.4- 0.2 pg WHO-TEQ/g間，SVOCs中檢測到了一些氯苯（Chlorinated Benzene）類和PAHs物質，魚類樣品中類戴奧辛化合物的濃度相對高於參考國外魚類樣品濃度。根據本研究結果顯示，石油工業活動可能排放相對高濃度的潛在毒性於工廠週遭水體及沉積底泥。

Dioxin-like contaminants have been extensively studied owing to their acute toxicity and negative impact on human health. The sources of these compounds are mainly human activities, including industrial and heat-treatment processes. Sampling from fish pond was performed to investigate the concentrations, toxic equivalents and profiles of Semi-Volatile Organic Compounds(Semi-Volatile Organic Compounds , SVOCs) and Dioxin-like contaminants near a petroleum industrial park. Sediments samples contained higher toxic equivalents (TEQs) than fish body. Total TEQs of PCDD/Fs in sediments from within the fish ponds ranged between 0.8 and 0.3 pg WHO-TEQ/g. And fish bodies ranged between 0.4 and 0.2 pg WHO-TEQ/g. Some analyzed Chlorinated Benzene(CB) and polyaromatic hydrocarbons PAHs in the sediment and fish samples were detected. These concentrations of Dioxin-like compounds for fish seem to be elevated by several times when compared to the reference foreign samples. From our study, it can be concluded that industrial activities from primarily a petroleum production plant have contributed high concentrations of the relative toxic potential in water body and sediments.
