在公海环境中检测到邻苯二甲酸酯增塑剂。对墨西哥湾的水、沉积物、空气和生物群以及北大西洋的水和空气样本进行了分析，发现含有2种邻苯二甲酸酯，即邻苯二甲酸二（2-乙基己基）酯（DEHP）和邻苯二甲酸二正丁酯（DBP）;还测定了多氯联苯（PCB）和滴滴涕（p，p“-DDT和p，p”-DDE）的浓度。与普遍存在的PCB和DDT一样，邻苯二甲酸酯增塑剂在几乎所有分析的样品中都被发现; DEHP在水和沉积物中的浓度高于PCB或DDT。这些研究中发现的浓度对环境的影响，加上这些增塑剂的持续高产量和广泛使用，需要进行评估。
Phthalate ester plasticizers were detected in the open-ocean environment. Samples consisting of water, sediment, air and biota from the Gulf of Mexico and of water and air from the North Atlantic were analyzed and found to contain 2 phthalate esters, di-(2-ethylhexyl) phthalate (DEHP) and di-n-dibutyl phthalate (DBP); the concentrations of polychlorinated biphenyls (PCB) and DDT (p,p''-DDT and p,p''-DDE) were also determined. Like the ubiquitous PCB and DDT, the phthalate plasticizers were found in almost all samples analyzed; DEHP was present at higher concentrations than the PCB or DDT in water and sediment. The environmental impact of the concentrations found in these studies, coupled with the continued high production and wide use of these plasticizers, requires assessment.
