- 摘要：在厦门岛及附近海域的轮渡码头、杏林湾、同安湾、黄厝4个地点现场采集牡蛎样品, 研究牡蛎全组织石油烃含量与其消化腺、鳃超氧化物歧化酶(SOD)、过氧化氢酶(CAT)活性之间的关系, 并探讨了将僧帽牡蛎抗氧化酶作为监测海洋石油污染的生物标志物(biomarker)的可能性.结果表明:(1)采自轮渡码头、杏林湾、同安湾、黄厝的牡蛎全组织石油烃含量分别为380.68、112.34、27.31、20.37μg/g;(2)牡蛎消化腺SOD、CAT活性均高于鳃;(3)牡蛎消化腺和鳃CAT、SOD活性均随石油烃含量的增加
- Abstract：The oyster %(Ostrea cucullata%) were collected from four stations around Xiamen island(Lundu port, Xinglin bay, Tong'an bay and Huangcuo). The biological respones measured included the level of petroleum hydrocarbon in whole tissue, the activity of super oxide dismutase (SOD) and catalase in digestive gland and gill. The results showed: (1) The content of petrolum hydrocarbon in oyster collected from four stations were 380.68, 112.34, 27.31 and 20.37μg/g wet, respectively; (2) The activity of SOD and catalase in digestive gland were higher than in gill;(3)Among the four stations, the SOD and catalase activity showed a good correlation with whole tissue petrolum hydrocarbon, which indicated that the antioxidant enzymes in oyster were suitable biomarker of marine oil pollution.
- Key words：oil pollution %Ostrea cuculiata% SOD catalase field study
