邻苯二甲酸酯（PAEs）作为增塑剂广泛应用于各种塑料制品中，其普遍存在和对环境的潜在危害引起了人们的关注。该研究首次提供了波斯湾北方沉积物中邻苯二甲酸酯分布的数据。到.为了确定16种PAEs的浓度，从2016年11月至2017年1月从Asalouyeh港海岸的工业站（IS），城市站（US），农业站（AGS）和天然野外站（NS）收集了26个沉积物样品。从IS、AGS、US和NS采集的样品中Sigma 16 PAE的平均值分别为78.08、11.69、46.56和5.180 μ g/g。结果表明，IS区和AGS区的Sigma 16 PAEs平均浓度显著高于US区和NS区（p < 0.05）。沉积物样品中邻苯二甲酸二（2-乙基己基）酯（DEHP）、邻苯二甲酸二正丁酯（DnBP）、邻苯二甲酸丁苄酯（BBP）和邻苯二甲酸二正辛酯（DnOP）的浓度顺序分别为。在所有收集的样本中均检测到DEHP，IS、US、AGS和NS地区的浓度平均值+/- SD分别为28.15 +/- 4.9、4.040 +/- 0.53、11.58 +/- 1.2和1.780 +/- 0.78 μ g/g。研究区沉积物中邻苯二甲酸酯的主要来源与工农业活动有关。这项研究的结果表明，Asalouyeh海岸的沉积物受到了严重的邻苯二甲酸酯污染。它们对水生生物和底栖生物表现出潜在的生态毒理学效应。因此，对该区域海洋生态系统的预测应引起有关部门的重视。
Phthalate acid esters (PAEs) are widely used as plasticizers in various plastic products and have aroused considerable concern over their ubiquitous presence and potentially hazardous effects on the environment. This research provides the first data on PAEs distribution in the sediments of northern part of the Persian Gulf. To. determine the concentration of 16 PAEs, 26 samples of sediments were collected from industrial stations (IS), urban stations (US), agricultural stations (AGS), and natural field stations (NS) from Asalouyeh Harbor coasts from Nov 2016 to Jan 2017. The mean values of Sigma 16PAEs in the samples taken from IS, AGS, US, and NS were 78.08, 11.69, 46.56, and 5.180 mu g/g, respectively. The results indicated that the mean concentrations of Sigma 16PAEs in the samples taken from IS and AGS areas were significantly higher (p < 0.05) than the ones taken from US and NS areas. The order of PAEs concentrations in sediment samples were as di(2-ethylhexyl) phthalate (DEHP), di-n-butyl phthalate (DnBP), butylbenzyl phthalate (BBP), and di-n-octyl phthalate (DnOP), respectively. DEHP was detected in all collected samples and the mean +/- SD of its concentration in the IS, US, AGS, and NS regions were as 28.15 +/- 4.9, 4.040 +/- 0.53, 11.58 +/- 1.2, and 1.780 +/- 0.78 mu g/g, respectively. The major sources of PAEs in the sediments collected from the study region were associated with the industrial and agricultural activities. The findings of this study indicated that the sediments of the Asalouyeh coasts are heavily contaminated with PAEs. They have shown potential ecotoxicological effects on the aquatic organisms and benthic. Therefore, more attention should be paid to prediction of the marine ecosystem in this region by the authorities.
