几种不同的植物能够从初始浓度为4.6 mg L-1和46 mg L-1的水中去除和解毒内分泌干扰物双酚A。双酚A似乎被五种牧草（羊茅、马齿草、多年生黑麦草、西伯利亚小麦草和白三叶草）和三种园艺植物（黄瓜、骨髓植物和萝卜）糖基化，转化为极性化合物，并作为残留物结合。败血性和无菌试验证实，微生物可以降解羊茅和萝卜，多年生黑麦草渗出物似乎含有转化双酚a的酶活性，但这种活性显然被微生物灭活了。虽然测试的禾本科植物比园艺植物更有效，但最适合植物修复双酚A的最佳植物种类尚未确定。在16天内有限的工厂测试并没有确定如何或哪些植物修复方法可以应用，但双酚A的去除效率和明显的转化证明了进一步的可行性，试点和不同废水的可处理性测试。(C) 2010 Elsevier Ltd.版权所有。
Several different plants are capable of removing and detoxifying the endocrine disruptor bisphenol A from water starting with initial concentrations of 4.6 mg L-1 and 46 mg L-1. Bisphenol A seems to be glycosylated, transformed to polar compounds, and bound as residue by five forage grasses, fescue, couch grass, perennial ryegrass, Siberian wheatgrass, and white clover, and three horticultural species, cucumber, marrow plant, and radish. Septic and axenic testing established that microbial degradation is possible for fescue and radish, and perennial ryegrass exudates seemed to contain enzymatic activity that transforms bisphenol A. but this activity is evidently deactivated by microorganisms. Although the grasses tested were more effective than the horticultural species, the optimal species of plants best suited for phytoremediation of bisphenol A was not determined. The limited plant testing during 16 d does not define how nor which phytoremediation practices can be applied, but the removal efficiency and evident transformation of bisphenol A justify further feasibility, pilot, and treatability testing of different wastewaters.
