| 摘 要： | 调查分析了莱州湾表层沉积物中16种优先控制多环芳烃(PAHs)含量以及来源,发现PAHs含量在239.2510-9~697.06 10-9之间,平均为499.9 10-9,其中芴、菲含量最高,分别为191.04 10-9、167.60 10-9.通过主成分分析,发现PAHs主要来源于木柴、煤炭、油类的燃烧以及油类泄露.并通过平均效应区间中值商法评价了PAHs污染的生态风险,发现莱州湾内面临PAHs污染的生态风险较小.莱州湾表层沉积物PAHs含量以及生态风险在近几年内呈现急速上升趋势.

| Abstract: | The content of 16 kinds of precedence-controlled Polycyclic Aromatic Hydrocarbons (PAHs) of surficial sediment in Laizhou Bay is investigated. The total PAHs content is between 239.25 10-9 to 697.06 10-9, with an average of 499.9 10-9. Flu and Phe are the highest content which is 191.04 10-9 and 167.60 10-9 respectively. The PAHs mainly come from the burning of wood, coal and fossil oil and the oil spill according to the principal component analysis. The ecological risk assessment is analyzed using the method of Mean effects range median-Quotient. The results show that the ecological risk is relatively low in Laizhou Bay. The total content and ecological risk of PAHs in surficial sediment of Laizhou Bay are rising rapidly in recent years. |
