为了评估内分泌干扰物的存在下处理的海洋排污口排放及其可能的影响，贻贝（贻贝galloprovincialis）被关在笼子里的环境混合区的桑坦德卫生系统的排污口，并在一个控制区。在30、60和90天后，收集样品以进行化学分析（金属、阴离子表面活性剂、烷基酚、双酚A、邻苯二甲酸酯和雌激素）、一般应激的生物标志物（溶酶体膜稳定性-LMS、组织病理学）和内分泌干扰的生物标志物（卵黄原蛋白样蛋白和性腺指数）。排污口和对照点的污染物水平没有显著差异，除了4-叔辛基苯酚在排污口较高。排污口区域的细菌计数较高。处理和对照贻贝之间没有检测到生物标志物的相关差异。一个显着减少LMS发生在两组后90天的笼子，表明可能与笼子或产卵后的生殖状态的压力情况。(C)2011爱思唯尔有限公司保留所有权利。
To assess the presence of endocrine disruptors in treated marine outfall discharges and their possible effects, mussels (Mytilus galloprovincialis) were caged in the environmental mixing zone of the outfall of the Santander sanitation system and in one control area. After 30, 60 and 90 days, samples were collected to perform chemical analyses (metals, anionic surfactants, alkylphenols, bisphenol A, phthalates and estrogenic hormones), biomarkers of general stress (lysosomal membrane stability-LMS, histopathology) and biomarkers of endocrine disruption (vitellogenin-like proteins and gonad index). There were no significant differences between outfall and control sites on contaminant levels, except for 4-tert-octyl-phenol which was higher in the outfall site. Bacteriological counts were higher in the outfall area. No relevant differences in biomarkers were detected between treated and control mussels. A significant reduction in LMS occurred in both groups after 90 days caging, indicating a stress situation possibly related to caging or to post-spawning reproductive state. (C) 2011 Elsevier Ltd.
