The adverse effects of endocrine disruptors (EDs) on aquatic wildlife and human health represent a current issue of high public concern. Substantial knowledge of the level of estrogenic EDs in fish has accumulated from field surveys. For this purpose, a survey of wild brown trout (Salmo trutta trutta) was carried out to assess the incidence of EDs in the feral fish population living in the Liri river (Abruzzi, Italy). The results of this study show that this aquatic environment possesses an estrogenic potency that triggered the increase of vitellogenin levels in both female and male trouts. Fish exposed to different pesticides and urban waste in downstream river showed higher vitellogenin levels in comparison to the headwater site. Furthermore, some trouts coming from the downstream reported the presence of several pesticides and fungicides, some of these banned several years ago.

内分泌干​​扰物对野生褐鳟（Salmo trutta trutta）中卵黄蛋白原浓度的影响。

内分泌干​​扰物（EDs）对水生野生生物和人类健康的不利影响代表了当前引起公众高度关注的问题。通过实地调查已经积累了对鱼类中雌激素EDs水平的大量了解。为此，对野生褐鳟（Salmo trutta trutta）进行了评估生活在利里河（意大利阿布鲁齐）的野生鱼类种群中EDs的发生率。这项研究的结果表明，这种水生环境具有雌激素效价，可触发雌性和雄性鳟鱼中卵黄蛋白原水平的增加。与上游水源地相比，下游河流中暴露于不同农药和城市垃圾的鱼类显示出更高的卵黄蛋白原水平。此外，下游的一些鳟鱼报告说存在几种农药和杀真菌剂，其中一些是几年前禁止的。
