Seawater, sediment, and aquatic organism samples were collected from 20 sampling sites in coastal environment of Dalian in August, 2011. The occurrence, distribution, and bioaccumulation of 20 antibiotics categorizing into three groups, including 14 sulfonamides (SAs), two chloramphenicols (CAPs) and four tetracyclines (TCs), were investigated. The results suggested that tetracyclines were the predominant antibiotics in the seawater (range: 2.11-9.23 ng L(-1)), while sulfonamides were the dominant antibiotics in both sediments (range: 1.42-71.32 μg kg(-1)) and aquatic organisms (range: 2.18-63.87 μg kg(-1)). The sorption coefficient Kd,s values revealed that sulfameter, sulfadiazine, sulfamethoxypyridazine, sulfamonomethoxine, chloramphenicol, and doxycycline presented higher sorption capacities than the other antibiotics. The average BAFs suggested that sulfamethazine, sulfamethiazole, sulfamonomethoxine, and doxycycline were potentially bioaccumulative, while sulfadiazine, sulfameter, sulfamethoxypyridazine, and chloramphenicol were bioaccumulative.
于 2011 年 8 月采集了大连沿海环境 20 个采样点的海水、沉积物和水生生物样本。研究了 20 种抗生素（分为 3 组，包括 14 种磺胺类、2 种氯霉素和 4 种四环素）的存在、分布和生物积累情况。结果表明，四环素是海水中的主要抗生素（范围：2.11-9.23ng/L），而磺胺类则是沉积物（范围：1.42-71.32μg/kg）和水生生物（范围：2.18-63.87μg/kg）中的主要抗生素。吸附系数 Kd,s 值表明，磺胺甲噁唑、磺胺嘧啶、磺胺二甲嘧啶、磺胺甲噁唑、氯霉素和强力霉素具有较高的吸附能力。平均 BAFs 表明，磺胺甲噁唑、磺胺噻唑、磺胺二甲嘧啶和强力霉素可能具有生物累积性，而磺胺嘧啶、磺胺甲噁唑、磺胺二甲嘧啶和氯霉素则具有生物累积性。
