The occurrence of β-blocker drugs in aquatic environments worldwide has caused increasing attention to their threat human health recent years. It is essential monitor these widely prescribed pharmaceuticals natural waters and sediments, helping us investigate potential risk humans ecosystems. In this study, a passive sampling technique, diffusive gradients thin-films (DGT), was systematically developed for eight frequently detected β-blockers. effective capacities target compounds were large enough the devices deploy several weeks. uptake all linearly correlated with deployment times during 7-day laboratory experiment agreed well theoretical line, except (e.g., ATL) due relatively slow rate. performance most independent varying pH values organic matter contents; only few affected, while application high-salinity needs be conducted caution. Field deployments DGT detect β-blockers situ rivers sediments proved that an tool fate environment, probes can provide information biogeochemical processes occurred sediment, especially at sediment–water interface. This novel approach will help understand behaviour assess risks, finally protect maintain sustainable development ecosystem.
