Historical trends of perfluorinated compounds from the sediment cores of East China Sea continental shelf and northern Taiwan Strait / 東海大陸棚及台灣海峽北部地區底泥岩心中全氟化物之濃度與污染趨勢

碩士 / 國立中山大學 / 海洋環境及工程學系研究所 / 104 / Cores collected, along the estuaries and harbors, from the East China Sea continental shelf and northern Taiwan Strait were used to reconstruct historical record of perfluorinated compounds (PFCs) contamination and to investigate the possible sources associated. Solid phase extraction (SPE) and HPLC-MS/MS were used in analyzing the concentration of PFCs. The results show that the concentration decreases with the depth. The range of concentration is ND~0.93 ng/g from B3 (near Fujian Shacheng Harbor) which is the highest among all the cores analyzed; while ND~0.42 ng/g from G1 (near Yangtze River estuary) which is the lowest. Similar to those found in other areas, the major compounds in sediment cores are PFOA and PFOS.
Total organic carbon content (TOC) and median particle size in the samples are found significantly correlated (r=-0.583, p=0.01). The samples in sediment cores, analyzed by principal components analysis (PCA) and hierarchical cluster analysis (HCA), were clustered mainly according to the relative abundance of PFNA, PFOA and PFOS. The abundant compounds in sediment cores near Taiwan are PFOA, PFOS and PFNA; while PFOA for those near China area. This is related to the characteristics of regional industries.
