Audouin's gull (Larus audouinii) is a very rare species endemic to the Mediterranean basin. A sub-population of an estimated 130 pairs is breeding in the Tuscan Archipelago, an area heavily polluted by mercury and chlorinated hydrocarbons. Here we present the data from 5 years spent monitoring the contaminant levels in the eggs of this species. Mercury, selenium, polychlorobiphenyls (PCBs) and DDE concentrations are two to five times higher than in similar species, such as the yellow-legged herring gull, nesting in the same area. The annual trends in these contaminant levels are discussed. In view of the endangered status of Audouin's gull, there is a need to observe closely the developing trend of contamination in this species.
奥杜邦鸥（Larus audouinii）是地中海盆地特有的一种非常珍稀的物种。据估计，有一个约130对的亚种群在托斯卡纳群岛繁殖，该地区受到汞和氯代烃的严重污染。在此，我们展示了对该物种鸟蛋中污染物水平进行5年监测所获得的数据。汞、硒、多氯联苯（PCBs）和滴滴伊（DDE）的浓度比在同一地区筑巢的类似物种黄腿鸥高两到五倍。文中讨论了这些污染物水平的年度变化趋势。鉴于奥杜邦鸥的濒危状况，有必要密切观察该物种的污染发展趋势。
