Abstract

The determination of hepatic ethoxyresorufin O-deethylase (EROD) has been used to assess the induction of the mixed function oxygenase system (MFO) of flounder (Platichthys flesus) in UK estuaries. Induction of the MFO system denotes possible exposure to certain organic contaminants (e.g. polycyclic aromatic hydrocarbons, polychlorinated biphenyls) and its measure has been incorporated in national monitoring programmes. This study presents EROD monitoring data from 5 UK estuaries taken between 1999 and 2001 and builds on data from previous years. The results reveal that for all sampled estuaries EROD values have been significantly (p < 0.05) elevated on the majority of occasions in comparison with the reference estuary, the Alde in Suffolk, UK. However, the limited temporal scale of the reported monitoring does not allow any conclusions to be drawn with respect to trends in the data. Possible factors influencing the data (size, gender, seasonality, reproductive status, etc.) are discussed and recommendations for continued monitoring are made.

摘要

肝乙氧基异吩恶唑酮O-脱乙基酶（EROD）的测定已被用于评估英国河口比目鱼（欧洲黄盖鲽）混合功能氧化酶系统（MFO）的诱导情况。MFO系统的诱导表明可能接触了某些有机污染物（如多环芳烃、多氯联苯），其测定已纳入国家监测计划。本研究展示了1999年至2001年间从英国5个河口采集的EROD监测数据，并基于前几年的数据展开。结果显示，与英国萨福克郡的参考河口奥尔德河相比，在大多数情况下，所有采样河口的EROD值均显著升高（p < 0.05）。然而，所报告监测的时间尺度有限，无法就数据趋势得出任何结论。讨论了影响数据的可能因素（大小、性别、季节性、生殖状态等），并提出了继续监测的建议。
