在这项研究中，在武汉封锁两周、三个月和八个月后，测量了废水和地表水中消毒副产物（DBP）和COVID-19相关药物的浓度。DBP浓度的时间变化很小，表明在COVID-19大流行期间加强消毒对水生环境中DBP的发生影响有限。相反，大流行导致废水和地表水中洛匹那韦和利托那韦的浓度显著增加。封锁后，这些药物在地表水中的高检测频率突出了它们在水生环境中的流动性和持久性。初步生态风险评估表明，地表水中的这些药物具有中度风险。由于全球形势仍在迅速发展，确诊的COVID-19病例数量持续激增，我们的研究结果表明迫切需要监测COVID-19相关药物，并对其在水环境中的生态毒性进行系统评估。
In this study, concentrations of disinfection byproducts (DBPs) and COVID-19 related pharmaceuticals in wastewater effluents and surface water were measured two weeks, three months and eight months after the lockdown in Wuhan. Little temporal variation in DBP concentrations suggested intensified disinfection during the COVID-19 pandemic had limited impacts on the occurrence of DBPs in the aquatic environment. In contrast, the pandemic led to a significant increase in concentrations of lopinavir and ritonavir in wastewater effluents and surface water. The high detection frequency of these pharmaceuticals in surface water after the lockdown highlighted their mobility and persistence in the aquatic environment. The initial ecological risk assessment indicated moderate risks associated with these pharmaceuticals in surface water. As the global situation is still rapidly evolving with a continuous surge in the number of confirmed COVID-19 cases, our results suggest a pressing need for monitoring COVID-19 related pharmaceuticals as well as a systematic evaluation of their ecotoxicities in the aquatic environment.
