dc.description.abstract2007年11~12月采集福建和粤东近岸海域的沉积物样品,对沉积物中的PAHS含量、组成进行研究,分析了研究海域沉积环境中PAHS的分布特征、来源,并利用lOng等人建立的评价模式对PAHS的生态风险进行了评价.研究结果为深入研究海域沉积环境中PAHS的地球化学行为提供了科学依据.结果表明:研究海域PAHS的含量范围为52.93~398.50 ng/g,平均值为170.30 ng/g,研究发现闽江径流是影响海区沉积物中PAHS含量分布的重要因素之一.通过不同环数PAHS的相对丰度和异构体比值分析,对研究海区沉积物中PAHS进行了溯源分析,发现厦门以北海域沉积物中的PAHS主要来自化石燃料燃烧,而厦门以南海域则主要来源于石油污染.生态风险评价结果显示,研究海域PAHS对生物体极少产生负面生态效应,潜在生态风险很小.
dc.description.abstractConcentration of PAHs were determined for sediment samples collected from the coastal line of Fujian Province and eastern Guangdong Province.The spatial distribution and sources of PAHs were studied.Based on Long et al.'s model,Ecological risk of PAHs was assessed also in this study.This study is helpful for further understand geochemical behavior of PAHs in coastal sediment environment.The results revealed that the concentrations of PAHs were in the range of 52.93 ~ 398.50 ng /g,with mean of 170.30 ng /g.The spatial distribution indicated that the PAHs in the sediment was mainly from terrigenous input,and Minjiang runoff was an important impact factor on the distribution of PAHs in the sediments.By analysis of the relative abundance of rings and isomer ratio of PAHs,it was found that PAHs in the coastal sediments north to Xiamen Bay were mainly from combustion,whereas other sediments received oil contamination.Ecological risk assessment indicated that in coastal sediment environment PAHs had few negative ecological effect to the living organisms with minimum ecological risk.
