摘要

This study evaluates the phytoremediation potential of Zea mays L. (DKC 3969) for removing psychotropic, antitussive, and anti-inflammatory pharmaceuticals from wastewater under sterile hydroponic conditions. Maize plants were exposed to buspirone (B), dextromethorphan (D), ibuprofen (I), paroxetine (P), sulpiride (S), and a combination of ibuprofen and dextromethorphan (I + D). Antidepressants B, P and S are increasingly used, but little is known about their fate in the environment and whether it will be possible to remove them in an ecologically friendly way. Results showed efficient uptake and translocation of B, D, and I, while P and S exhibited limited shoot translocation. Most drugs induced only mild oxidative stress, with S causing the strongest stress response but without affecting growth parameters, including elevated reactive oxygen species production and antioxidant activity. All pharmaceuticals elevated heat shock proteins HSP70 and HSP90 in maize leaves and roots, suggesting their role as biomarkers of xenobiotic-induced stress. Enhanced activity of glutathione-S-transferase and peroxidases, particularly in response to S and I + D, suggests initiation of biotransformation mechanisms. Overall, maize demonstrated resilience and effective pharmaceutical uptake, supporting its use as a phytoremediation strategy.
