In this study we analyzed and characterized 29 psychoactive remedies, illicit drugs and their metabolites in single stages of wastewater treatment plants in the capital city of Slovakia. Psychoactive compounds were present within all stages, and tramadol was detected at a very high concentration (706 ng/L). Significant decreases of codeine, THC-COOH, cocaine and buprenorphine concentration were observed in the biological stage. Consequently, we were interested in the possibility of alternative tertiary post-treatment of effluent water with the following aquatic plants: Cabomba caroliniana, Limnophila sessiliflora, Egeria najas and Iris pseudacorus. The most effective plant for tertiary cleansing was I. pseudacorus which demonstrated the best pharmaceutical removal capacity. After 48 h codeine and citalopram was removed with 87% efficiency. After 96 h were all analyzed compounds were eliminated with efficiencies above 58%.
在本研究中，我们分析并表征了斯洛伐克首都污水处理厂单个阶段中的29种精神活性药物、非法药物及其代谢物。所有阶段均存在精神活性化合物，且检测到曲马多浓度极高（706纳克/升）。在生物阶段观察到可待因、四氢大麻酚羧酸（THC-COOH）、可卡因和丁丙诺啡浓度显著下降。因此，我们对以下水生植物对出水进行替代性三级后处理的可能性感兴趣：卡罗莱纳水盾草、穗状狐尾藻、细叶蜈蚣草和黄菖蒲。用于三级净化最有效的植物是黄菖蒲，其展现出最佳的药物去除能力。48小时后，可待因和西酞普兰的去除效率达87%。96小时后，所有分析的化合物去除效率均高于58%。
