【摘要】：以褐菖湁(Sebastiscus marmoratus)细胞色素P4501A四种生物标志物,即鳃丝EROD活性、肝EROD活性、肝CYP1A mRNA和肝CYP1A蛋白为指标,在泉州湾海域选择6个站位(包括1个对照站位),开展了为期两周的野外监测实验,研究了上述生物标志物的变化特征以及它们同表层海水中石油类含量和沉积物物中16种优先监控的PAHs含量之间的相关性,并利用新一代综合生物标志物响应指数法(IBRv2)对监测站位石油类和PAHs污染效应进行了评价.结果显示,不同站位的上述四种生物标志物变化趋势基本一致;生物标志物的变化与相应站位表层水中石油类含量及沉积物中PAHs总含量相吻合;IBRv2分析结果表明,各监测站位IBRv2指数介于1.5~4.2之间,其中2号站环境污染压力最大,4号站最小.在复杂的海洋污染条件下,采用CYP1A多种生物标志物监测技术能够更加全面反映石油类等污染及其生物效应状况.
[Abstract]:Four biomarkers of cytochrome P4501A of Sebastiscus marmoratus, I. e., Gill EROD activity, liver EROD activity, liver CYP1A mRNA and liver CYP1A protein, were used as indexes. A two-week field monitoring experiment was conducted by selecting 6 stations (including one control station) in Quanzhou Bay. The variation characteristics of these biomarkers and their correlation with petroleum content in surface seawater and 16 priority monitored PAHs contents in sediments were studied. A new generation of synthetic biomarker response index (IBRv2) was used to evaluate the pollution effects of oil and PAHs at monitoring stations. The results showed that the change trend of the above four biomarkers in different stations was basically the same, and the change of biomarkers was consistent with the oil content in surface water and the total content of PAHs in sediments. The IBRv2 index of each monitoring station is between 1.5 and 4.2, among which station 2 has the largest environmental pollution pressure and station 4 the smallest. Under the condition of complex marine pollution, the CYP1A biomarker monitoring technology can more comprehensively reflect the oil pollution and its biological effects.
