碩士 / 國立屏東科技大學 / 環境工程與科學系所 / 103 / This study investigate the Dioxin-like compounds concentration and toxic contributions in fish farm's sediments nearby the Petroleum Industrial Park within two season, and used Fugacity Model simulate environment distribution in two season of Dioxin-like compounds were compared with measured values. In this study, the classified region codes is according to the sampling locations within a radius of the Petroleum Industrial Park from 0~10km,11~20km and 20km outside respectively, and classified to near zone,far zone and remote districts. From the results show that wet season and dry season sediments ΣPCDD / Fs concentration ranges are 30.70 ~ 988.25 pg / g (dw)、24.68 ~ 182.03 pg / g (dw) respectively. After TEF conversion, wet season and dry season sediments ΣPCDD / Fs toxicity equivalency quantity (TEQ) ranges are 0.13~1.62 pgWHO-TEQ/g (d.w.)、0.361~3.560 pgWHO-TEQ/g (d.w.) respectively. Wet season and dry season sediments ΣPCBs concentration ranges are 10.47~184.86 pg / g (d.w.)、10.45~89.49 pg / g (d.w.) respectively. After TEF conversion, wet season and dry season sediments ΣPCBs TEQ ranges are 0.010~0.108 pgWHO-TEQ/g (d.w.)、0.03~0.18 pgWHO-TEQ/g (d.w.) respectively. The concentrations of PCDD/Fs、PCBs measured in various regions of the wet season, it were greater than the measured concentration of each region of the dry season. PCDDs change with the seasons (wet season to the dry season) to reduce the toxicity contribution, PCDFs change with the seasons (wet season to the dry season) to increase the toxicity contribution.Select the appropriate Fugacity Model simulation parameters to calculate PCDD / Fs concentrations, displays the calculated range of analog values approaches the value of PCDD / Fs actual measurement in wet and dry season sediments.
