| Summary: | 碩士 === 國立中山大學 === 海洋環境及工程學系研究所 === 88 === Twenty-two sediment samples were collected from Kaohsiung Harbour, and it’s
neighboring coastal area, Taiwan and analysed for a suite of n-C10-C35 aliphatic
hydrocarbons and fifteen polycycilc aromatic hydrocarbons (PAHs). The average total
concentration of n-alkanes was 4.327 μg/g dry wt. (0.461-22.601 μg/g dry wt.) and
PAHs was 0.588 μg/g dry wt. (0.088-1.75 μg/g dry wt.). The highest n-alkanes and
PAHs concentrations were recorded in samples from D and A stations in Kaohsiung
Harbour ; stations D and A are near the outlets of Chyan-Jenn and Jen-Ai rivers,
respectively. The sources of n-alkanes are probably contributed form origins of
petrogenic, biogenic and higher plants according to the value of CPI (carbon
preference index), chromatogram of UCM (unresolved complex materials), and n-C16
ratio etc.; while PAHs were contributed mainly from combustion in coastal areas and
petrogenic in harbour areas based on the ratios of total combustion and LMW/HMW
ratios. Overall, sediment concentrations of n-alkanes and PAHs in Kaohsiung coastal
area were similar to literature in the world. The potential for biological effects due to
PAHs is found to be low based as their individual PAHs concentrations are in general
lower than effects most existed sediment quality guidelines, except Acenaphthaene,
Anthracene, Benzo[a]anthracene, and Fluorene.
