Abstract
Six sediment cores collected at four contaminated river mouths and two harbor entrances in Kaohsiung Harbor (Taiwan) were analyzed to evaluate the sources and potential toxicity of polycyclic aromatic hydrocarbons (PAHs). PAHs presented the wide variations ranging from 369 ± 656 to 33,772 ± 14,378 ng gâ1 at the six sampling sites. The composition of PAHs presented a uniform profile reflecting the importance of atmospheric input from vehicle exhausts or coal combustion in the river mouths. PAHs diagnostic ratios indicated a stronger influence of coal combustion in the Salt River mouth and the prevalence of petroleum combustion and mixed sources in the other rivers and harbor entrances. PAHs toxicity assessment using the mean effect range-median quotient (m-ERM-q: 0.011-1.804), benzo[a]pyrene-toxicity equivalent (TEQcarc: 22-2819 ng TEQ gâ1), and dioxin-toxicity equivalent (TEQfish: 37-5129 pg TEQ gâ1) identified the Salt River mouth near the industrial area of the harbor as the most affected area.
