Seawater, sediment, seagrass and fish from several sites along the Tunisian coast were monitored for several phthalate esters (PAEs) and non-phthalate plasticizers (NPPs) during 2018-2019. In water and sediment, NPPs were higher than PAEs, being di(2-ethylhexyl) phthalate (DEHP, 0.0717 and 4.59 μg/g), and di(2-ethylhexyl) terephthalate (DEHT, 0.634 and 2.42 μg/g) most abundant. As expected, sediments acted as a sink for plasticizers, thus revealing a stronger contamination than water. Seagrass was less contaminated than fish, being DEHP (0.726 and 1.77 μg/g) and DEHT (9.19 and 23.2 μg/g) predominant. Biota poorly concentrated/accumulated plasticizers from water and sediment depending on the logK and water solubility of single congeners. The spatial distribution of plasticizers was affected by the proximity to anthropogenic sources and the rate of coastal currents; whereas their seasonal variation may be related to the length of time of touristic/industrial inputs and factors such as rainfall and urban stormwater runoff.
2018-2019 年期间，监测了突尼斯沿海几个地点的海水、沉积物、海草和鱼类中的多种邻苯二甲酸酯（PAEs）和非邻苯二甲酸酯类增塑剂（NPPs）。在水和沉积物中，NPPs 的含量高于 PAEs，其中含量最高的是邻苯二甲酸二（2-乙基己基）酯（DEHP，0.0717 和 4.59μg/g）和邻苯二甲酸二（2-乙基己基）酯（DEHT，0.634 和 2.42μg/g）。正如预期的那样，沉积物是增塑剂的汇，因此其污染程度比水更强。海草的污染程度低于鱼类，其中 DEHP（0.726 和 1.77μg/g）和 DEHT（9.19 和 23.2μg/g）是主要成分。生物群根据单一同系物的 logK 和水溶解度，从水和沉积物中浓缩/积累增塑剂的能力较差。增塑剂的空间分布受到人类活动源的接近程度和海岸潮流率的影响；而其季节性变化可能与旅游/工业投入的时间长短以及降雨和城市雨水径流等因素有关。
