本研究主要分析台灣翡翠水庫顆粒物質之脂肪族碳氫化合物 (aliphatic
hydrocarbons compositions, AHCs) C10 至C35 直鏈烷濃度及組成,藉由生物指標
(bio-marker)觀念以評估顆粒物質中有機物質來源及相對貢獻量。樣品包含沉積
物、20 及70 公尺深沉降顆粒、表水、20 及70 公尺深懸浮顆粒,其中沉積物2002
年採樣,沉降顆粒及懸浮顆粒為2004~2005 年採樣之樣品。分析前處理包括索氏
萃取,銅粒除硫及管柱淨化等,以氣相層析儀及火焰離子偵測器 (GC-FID) 進行
化學分析。沉積物總直鏈烷濃度平均為3.8±2.6 μg/g (n=12),直鏈烷優勢種順序

平均值為4.16±0.57 (n=12),顯示中、長碳鏈奇數碳直鏈烷之生物來源訊號明顯;
TAR (Terrigenous to Aquatic Ratio) 平均值為15.3±22.74,整體以陸生貢獻長碳鏈

Aliphatic hydrocarbon compositions (AHCs, C10-C35 n-alkanes ) from a sediment core, suspended solids and settling particles of the Feitsui reservoir were Soxhlet extracted and GC-FID analyzed. The calculated biomarker molecule proxies were used to indicate the organic matter origins and their relative contributions. The total AHCs concentrations from sediments averaged 3.8±2.6μg/g(n=12), primarily dominating by the odd long-chain n-alkanes, such as C31、C33、C29、C35 and C27, approximately 60% of the total AHCs concentrations. The predominance of odd long-chain n-alkanes suggests the major contribution from terrestrial plants. The averaged CPI (Carbon preference index) value of 4.2±0.6 and the averaged TAR (Terrigenous to Aquatic Ratio) value of 15.3±22.74 also supported the obvious biogenetics features from terrestrial plants. The sampled settling particle represented 20% of annual settling fluxes and the total AHCs averaged 8.23μg/g weighted by particle settling fluxes. The averaged CPI value of 4.07±1.52 and the predominance of odd long-chain (C27、C29、C31 ) indicated biogenetics feature that AHCs in settling particles from terrestrial plants, corresponding to the main source of Feitsui Reservoir sediment is settling from those particles contributed by typhoon and carried terrestrial plants surrounding reservoir. The total AHCs concentrations of sampled suspended solid averaged 253.01±159.3 4μg/g (n=9) and the averaged CPI value of 1.13±0.14(n=9), indicated minor biogenetic feature in the suspended solid. However, the detected odd-short-chain n-alkane of C17 suggested the biogenetics feature from suspended phytoplankton.
