The spatial distribution and seasonal variation of 16 phthalate esters (PAEs) in water, suspended particulate matter (SPM) and sediment were investigated in the Jiulong River estuary, Fujian, Southeast China. Of the 16 PAE congeners analyzed, only six PAEs, including dimethyl phthalate (DMP), diethyl phthalate (DEP), diisobutyl phthalate (DIBP), di-n-butyl phthalate (DBP), di(2-ethylhexyl) phthalate (DEHP) and diisononyl phthalate (DINP), were identified and quantified. The total concentrations of the six PAEs (∑PAEs) detected for all seasons ranged from 3.01 to 26.4μg/L in water, 1.56 to 48.7mg/kg in SPM, and 0.037 to 0.443μg/kg in sediment. DEHP, DIBP and DBP were the most abundant PAE congeners in all of the water, SPM and sediment phases. The spatial distributions of PAEs in the estuary were controlled not only by the riverine runoff, seasons, hydrodynamic condition and human activities but also the physicochemical properties of PAEs.
对中国东南部福建省九龙江河口的水、悬浮颗粒物（SPM）和沉积物中16种邻苯二甲酸酯（PAEs）的空间分布和季节变化进行了研究。在所分析的16种PAE同系物中，仅鉴定并定量了6种PAEs，包括邻苯二甲酸二甲酯（DMP）、邻苯二甲酸二乙酯（DEP）、邻苯二甲酸二异丁酯（DIBP）、邻苯二甲酸二正丁酯（DBP）、邻苯二甲酸二（2-乙基己基）酯（DEHP）和邻苯二甲酸二异壬酯（DINP）。所有季节检测到的6种PAEs（∑PAEs）总浓度在水中为3.01至26.4μg/L，在SPM中为1.56至48.7mg/kg，在沉积物中为0.037至0.443μg/kg。DEHP、DIBP和DBP是所有水相、SPM相和沉积物相中含量最高的PAE同系物。河口PAEs的空间分布不仅受河流径流、季节、水动力条件和人类活动的控制，还受PAEs物理化学性质的影响。
