The occurrence and fate of alkylphenols in various matrices of the Seine River Estuary were studied. Nonylylphenols (NP) and nonylphenol polethoxylates (NPEs) were monitored in surface dissolved water, suspended particulate matter (SPM) and in a copepod, Eurytemora affinis from November 2002 to January 2004. NPs, nonylphenol mono and diethoxylates (NP1EO, NP2EO) and nonylphenol-ethoxy-acetic-acid (NP1EC) were detected and measured in all dissolved water and SPM samples whereas nonylphenoxy-acetic-acid (NP2EC) was only found sporadically in dissolved water samples. Seasonal variation of total concentrations of NPs and NPEs, ranging, respectively from 399 to 2214ngl(-1) and from 405 to 9636ngg(-1), were measured in the dissolved water and in the SPM. Significant decreases were observed in the water-column during the maximum biological activity periods in spring and autumn. Furthermore, increasing levels were observed in the SPM during the winter period. High concentrations of NP1EO and NP were detected in all copepod samples, ranging from 3423 to 6406ngg(-1). This study is the first to report high levels of endocrine disruptors in estuarine copepods.
对塞纳河河口不同基质中烷基酚的出现情况和归宿进行了研究。在2002年11月至2004年1月期间，对表层溶解水、悬浮颗粒物（SPM）以及一种桡足类动物——近亲真宽水蚤中的壬基酚（NP）和壬基酚聚乙氧基醚（NPEs）进行了监测。在所有溶解水和SPM样本中均检测并测定出了NP、壬基酚单乙氧基醚和二乙氧基醚（NP1EO、NP2EO）以及壬基酚乙氧基乙酸（NP1EC），而壬基酚氧基乙酸（NP2EC）仅偶尔在溶解水样本中被发现。在溶解水和SPM中测定了NP和NPEs总浓度的季节性变化，其范围分别为399至2214ngl(-1)以及405至9636ngg(-1)。在春季和秋季生物活性最高的时期，水柱中的浓度显著下降。此外，在冬季期间，SPM中的浓度有所上升。在所有桡足类动物样本中均检测到高浓度的NP1EO和NP，范围为3423至6406ngg(-1)。本研究首次报告了河口桡足类动物中存在高浓度的内分泌干扰物。
