碩士 / 國立屏東科技大學 / 環境工程與科學系所 / 102 / This study is to investigate about the Dioxin-like compounds concentration of farm-risedfisharound of petrochemicalindustrial areaduring wet season to dry season (from June to December), and expectto learn about thepetrochemical industrial arealocated inthe perimeter offarmedfishpondsof bioaccumulation from bio-sediment accumulation factor (BSAF). In this study, the classified region codes is according to the sampling locations within a radius of the petrochemical industrial zone from 5 km, 12 km and 22 kmrespectively, and classified to inside circle area, outside circle area and far area.From thesurveyed results showthat the average concentration’s range of PCDD/Fs is between 62.71 and 8843.52 pg/g (d.w.), PCBs is between 16.30 and 229.20pg/g (d.w.), in the wet season of all regions of fish and sediment. And the average concentration’s range of PCDD/Fs and PCBs are between 38.24 and143.28 pg/g (d.w.), 52.83 and 260.59 pg/g (d.w.) respectively in the transform season. As in the dry season, PCDD/Fs and PCBs’s average concentrations range are between 24.68 and131.90 pg/g (d.w.), 12.37 and 154.71pg/g (d.w.) respectively. From the BSAF surveyed results show, in three seasons of all regions measured BSAF are is larger than 1 , and the BSAF of PCDD/Fs will be reduced with the seasons change, but in transform season, the BSAF of PCBs is the highest than the other seasons.The BSAF ofPCBs at other areas, expect inside circle area, the dry season is more higherthan the wet season. Furthermore, the surveyed results indicated thatthe farm-risedfish had happened the bioaccumulation on all regions.Among them of bioaccumulation, the most obvious is in the wet season.
