“…The use of active sampling to monitor the occurrence of pharmaceuticals in the environment has a certain contingency, and some of the areas that are difficult to collect from pose challenges. There has been a study of the use of remotely controllable electronic devices instead of manual sampling, and there have also been studies using passive sampling techniques to minimize contingency [ 47 , 48 , 49 ]. Therefore, we believe that combining passive sampling techniques with electronic devices is a research direction worth exploring.…”

Various studies have shown that the heavy use of pharmaceuticals poses serious ecological risks, especially in metropolitan areas with intensive human activities. In this study, the spatial distribution, sources, and ecological risks of 29 pharmaceuticals in 82 surface waters collected from the North Canal Basin in Beijing were studied. The results showed that the pharmaceutical concentrations ranged from not detected to 193 ng/L, with ampicillin being undetected while ofloxacin had a 100% detection frequency, which indicates the widespread occurrence of pharmaceutical pollution in the North Canal Basin. In comparison with other freshwater study areas, concentrations of pharmaceuticals in the North Canal Basin were generally at moderate levels. It was found that pharmaceutical concentrations were always higher in rivers that directly received wastewater effluents. Source analysis was conducted using the positive matrix factorization model. Combining the spatial pollution patterns of pharmaceuticals, it has been found that wastewater effluents contributed the most to the loads of pharmaceuticals in the studied basin, while in suburban areas, a possible contribution of untreated wastewater was demonstrated. Risk assessment indicated that approximately 55% of the pharmaceuticals posed low-to-high ecological risks, and combining the results of risk analyses, it is advised that controlling WWTP effluent is probably the most cost-effective measure in treating pharmaceutical pollution.

“…By combining the effective concentration of pollutants monitored by DGT methods, the toxic effects and potential risks of pollutants in environmental media can be accurately characterized to assess the environmental risk. At present, there have been reports on the monitoring of PAEs [100] and three antiviral corona virus disease 2019 (COVID-19) drugs [124] in water and the risk assessment of human health and the ecological environment using DGT, while the environmental risk assessment in soil mainly focuses on heavy metals [48]. The concentration and toxicity of heavy metals in contaminated soil [125], the accumulation in crops [45,126] and earthworms [79], and even human health risks [127] were accurately and effectively evaluated using DGT technology, the DIFS model [128] or combined with BCR [62], biogeochemical fractionation [129], whole-cell bioreporter [125], and physiological-based extraction tests [127].…”

In recent years, the diffusive gradients in the thin films (DGT) technique has also been increasingly applied to assess the bioavailability of heavy metals and organic pollutants in the soil. The combination of binding and diffusion phases made from different materials allows for the targeted determination of different target substances. This review briefly introduces the compositions and development of the DGT technique and analyzes the composition structure of DGT and the impact of environmental factors, such as pH, ion strength (IS), and dissolved organic matter (DOM), on the bioavailability evaluation of heavy metals and organic pollutants in soil. Finally, the application potential and broad application prospects of the DGT technique were expected. In addition, standardized DGT technique methods and calibration procedures are conducive to the establishment of a more stable and reliable measurement system to enhance the robustness of the DGT technique application in the soil.

“…Well-known AVDs such as OT and RT are used in treating influenza, SARS, MERS, HIV, and are also examined to cure COVID-19 ( Krasucka et al, 2022 ). The entrance of AVDs and their metabolites into already contaminated pharmaceutical ecosystems enhance the toxicological risks to the natural ecosystem and humans ( Cao et al, 2022 ). These pollutants also have been recognized as one of the persistent contaminants in wastewater.…”
