Phthalate esters (PAEs) are known organic endocrine disruptors. The distribution of 10 PAEs in sediments of Kaohsiung Harbor of Taiwan was studied using organic solvents extraction and quantified by gas chromatography/mass spectrometry. The average concentration of total PAEs (ΣPAEs) in the sediment was 8713±11,454ng/g dw with di-(2-ethylhexyl) phthalate (DEHP) (3630ng/g-dw) and diisononyl phthalate (DiNP) (3497ng/g dw) being the major species, which constitutes of 41.7% and 40.1% of ΣPAEs. PAEs concentration was relatively high near the river mouths, especially in Love River mouth, and diminished toward the harbor. Based on the sediment quality guidelines developed from previous studies, several of the observed PAE levels exceeded the Maximum Contaminant Level, especially for DEHP and thus may cause adverse effect in aquatic organisms.
邻苯二甲酸酯（PAEs）是已知的有机内分泌干扰物。本研究使用有机溶剂萃取法对台湾高雄港沉积物中的 10 种邻苯二甲酸酯进行了研究，并通过气相色谱/质谱法进行了定量分析。沉积物中总邻苯二甲酸酯（ΣPAEs）的平均浓度为 8713±11454ng/g dw，其中邻苯二甲酸二（2-乙基己基）酯（DEHP）（3630ng/g-dw）和邻苯二甲酸二异壬酯（DiNP）（3497ng/g dw）为主要成分，占ΣPAEs 的 41.7%和 40.1%。在河口附近，尤其是爱河河口附近，PAEs 浓度相对较高，而向港口方向则逐渐降低。根据先前研究制定的沉积物质量基准，部分观察到的邻苯二甲酸酯水平超过了最大污染物水平，特别是 DEHP，因此可能对水生生物产生不利影响。
