于2007年4月和7月在胶州湾3个采样点采集栉孔扇贝。评价生物标志物的响应，以评估该地区的扇贝生理状态和污染。与S1位点相比，S2和S3位点芳烃羟化酶活性显著升高（P < 0.05），谷胱甘肽S-转移酶活性显著降低（P < 0.05）。DNA碱性解旋水平。通过DNA蛋白质交联、蛋白质羰基化和脂质过氧化反应的检测，揭示了扇贝的氧化应激状况。各生物标志物含量在不同季节间差异显著（P < 0.05），在消化腺和鳃间差异显著（P < 0.05）。研究结果为海洋环境多重污染评价提供了参考数据，并表明生物标志物的选择受组织类型和季节的影响，因此在使用生物标志物进行环境评价时应考虑这些因素。(c)2012爱思唯尔有限公司保留所有权利。
Scallops (Chlamys farreri) were collected at three sites in the Jiaozhou Bay, China in April and July 2007. The responses of biomarkers were evaluated for assessment of physiological status of scallops and pollution in the areas. Compared with site S1, the activity of aryl hydrocarbon hydroxylase was induced notably (P < 0.05) and glutathione S-transferase activity was inhibited significantly (P < 0.05) in S2 and S3. The levels of DNA alkaline unwinding. DNA protein crosslinks, protein carbonyl and lipid peroxidation were tested and indicated the oxidative stress situation of scallops. There was significant difference of biomarker levels between sampling seasons (P < 0.05), and between digestive gland and gill (P < 0.05). The results provided the reference data for multiple-pollution assessment in the marine environment and indicated that tissue type and seasons affect biomarkers, therefore these factors should be taken into consideration when biomarkers are used for environmental assessment purposes.
