Wastewater treatment plants (WTTPs) contribute to anthropogenic chemical contamination through the release of treated effluent. A constructed wetland (CW) interfaced with a WTTP could potentially purify and naturalize effluent water. This pilot study aimed to acquire baseline chemical data on the fate and distribution of phthalates in the water, sediment, and vegetation (Typha spp.) of a fully operational horizontal subsurface flow CW adjoined to a WWTP in Oregon, USA. Sample collection followed the flow of water from entrance to exit of the CW. Dibutyl phthalate (DBP) and bis(2-ethylhexyl) phthalate (DEHP) were the most abundant analogs in all matrices. Results indicate reduction of phthalates in water exiting the CW. Significant concentrations of DBP, DEHP, and other water-soluble phthalates were found in the shoots of Typha, indicating plant uptake as a potentially important removal mechanism.

全面运营的人工湿地中邻苯二甲酸盐在水，沉积物和香蒲中的缓解和分布调查：一项先导研究。

废水处理厂（WTTP）通过释放处理后的废水而导致人为化学污染。与WTTP相连的人工湿地（CW）可能会净化和自然化废水。这项初步研究旨在获取有关邻苯二甲酸酯在水，沉积物和植被中的命运和分布的基线化学数据（香蒲属。），在美国俄勒冈州与污水处理厂相连的完全可操作的水平地下流CW。样品的收集遵循水从入口到出口的流动。邻苯二甲酸二丁酯（DBP）和邻苯二甲酸二（2-乙基己基）酯（DEHP）是所有基质中含量最丰富的类似物。结果表明离开连续水的水中邻苯二甲酸盐的减少。在香蒲的芽中发现了高浓度的DBP，DEHP和其他水溶性邻苯二甲酸酯，表明植物吸收是潜在的重要去除机理。
