碩士 / 崑山科技大學 / 環境工程研究所 / 100 / This study is to investigate the polycyclic aromatic hydrocarbons (PAHs) Port sediment ecological risk assessment and chemical fingerprinting. East of the island''s two major fishing port for the the Hualien fishing port and successful fishing port in recent years with the civilization and progress of science and technology, energy use, from the traditional coal mines have been converted to oil, natural gas ... and so on, people leisure and quality of life rising, the Hualien fishing port and the successful fishing port from the traditional fishing is gradually turning into a leisure and tourism in the composite port, the relative type of vessel within the port area is also more diversified. By the Council of Agriculture Fisheries is a statistical Hualien fishing port in the 95 to 99 vessels the amount of an average of 381 successful fishing port 328 can be seen Minato work boats, fishing, transportation and other maritime activities, resulting in the ship shipping caused by marine oil spills, emissions, and engine cooling water emissions, pollution, ecological risk of contamination of the entire ocean is relatively upgrade. Which polycyclic aromatic hydrocarbons, polycyclic Aromatic Hydrocarbons in oil pollutants, Port of ecological environment and human is possible negative impact. As the ecological risk assessment is a systematic, principled framework and methods, this research methods refer to the U.S. Environmental Protection Agency Consensus-Based Sediment Quality Guidelines (CBSQG) as sediment ecological risk assessment basis. The guidelines, two levels, a relatively low impact on the ecological threshold concentration effect of the TEC (threshold effect concentration), the other is the higher ecological impact that may affect the concentration of the PEC (probable effect concentration), to two levels as forecast. In addition, Long et al. Used to determine the potential ecological risk of organic pollutants in marine and estuarine sediment threshold effect concentration (threshold effects level, TEL), and the possible effect concentrations (probable effects level, the PEL), both also be regarded as ecological risk assessment of the sedimentary material quality standards. However, sediment is often a combination of a variety of pollutants, there may besynergies in the different pollutants. Therefore of ERL (Effects, Range Low), the pollutant concentration exceeds its value may be adverse ecological impact, ERM (Effects Range the Median), the pollutant concentration exceeds its value to adverse ecological impacts, indirect assessment of a mixture of estuarine sediment toxicity.
