The aim of the research was to evaluate the response of three tropical species (), respect their tolerance and removal capacity of pharmaceutical and personal care products (PPCPs), namely acetylsalicylic acid, ibuprofen, methyl hydrojasmonate (cis - MDJM), galaxolide, tonalide, caffeine, naproxen, ketoprofen, and diclofenac. The study was undertaken in two stages (Stage I - Tolerance; Stage II - Removal) of 21 days each. In Stage I, it was found evidence that from 1,000 μg L the plants show decaying responses, being the species with the best responses to tolerance and adaptation. The results of Stage II indicated that tonalide and ketoprofen compounds were 99% removed during the first 24 hours of exposure; acetylsalicylic acid, ibuprofen, galaxolide, and naproxen compounds were 80% eliminated, and caffeine and diclofenac products presented lower removal rates during same time. The study allowed the identification of two compound blocks, PPCPs that are sorbed by plants (acetylsalicylic acid, ibuprofen, MDJM, caffeine, galaxolide, and tonalide), and highly photodegradable compounds (ketoprofen, naproxen, and diclofenac). These findings open the possibility for further research about using plants adapted to tropical conditions, for PPCP removal from wastewaters in real scale nature-based systems such as treatment wetlands.
该研究的目的是评估三种热带物种对药物和个人护理产品（PPCPs）的耐受性和去除能力，这些产品包括乙酰水杨酸、布洛芬、茉莉酮酸甲酯（顺式-MDJM）、佳乐麝香、吐纳麝香、咖啡因、萘普生、酮洛芬和双氯芬酸。该研究分两个阶段进行（第一阶段-耐受性；第二阶段-去除），每个阶段为期21天。在第一阶段，发现有证据表明，当浓度达到1000μg/L时，植物表现出衰退反应，[此处原文缺失具体物种信息]是对耐受性和适应性反应最佳的物种。第二阶段的结果表明，在暴露的前24小时内，吐纳麝香和酮洛芬化合物的去除率达到99%；乙酰水杨酸、布洛芬、佳乐麝香和萘普生化合物的去除率为80%，而咖啡因和双氯芬酸产品在同一时间段内的去除率较低。该研究确定了两个化合物组，即被植物吸附的PPCPs（乙酰水杨酸、布洛芬、MDJM、咖啡因、佳乐麝香和吐纳麝香）和高光降解性化合物（酮洛芬、萘普生和双氯芬酸）。这些发现为进一步研究利用适应热带条件的植物在实际规模的自然系统（如处理湿地）中去除废水中的PPCPs开辟了可能性。
