The project has summarized both domestic and foreign persistent organic pollutants (POPs) management and the industrial POPs usage in Taiwan. It also investigated the concentrations of perfluorinated compounds (PFCs), Dechlorane Plus (DP), and UV-328 in wastewater. The analysis of 23 samples revealed that the concentrations of 18 PFCs ranged from 0.00118 to 2.25 μg/L. No syn-DP or anti-DP was detected in 22 water samples, while the concentration of UV-328 was detected in 20 samples, ranging from 0.00754 to 16.9 μg/L. In addition, the project investigated the concentrations of nine pharmaceutical compounds in wastewater from domestic hospitals, public sewage treatment plants, and environmental water bodies. The highest concentration of pharmaceuticals in hospital raw wastewater was observed for ceftazidime (2.34–6,480 μg/L), and the highest concentration in hospital effluent was also for ceftazidime (0.244–2,390 μg/L). In public sewage treatment plants, the highest detected concentration in raw wastewater was for metformin (57.1 and 101 μg/L), and in effluent, the highest concentration was again for ceftazidime (9.23 and 11.6 μg/L). Only metformin was detected in environmental water bodies at concentrations exceeding 1 μg/L. To ensure river water quality, the project also conducted surveys on ammonia nitrogen, boron, dioxins, and total mercury of coal in coal-fired power plants, assessing the pollution risk of wastewater discharge. The findings indicated that two electroplating industries had effluent boron concentrations exceeding the effluent standard. Furthermore, the project assisted in drafting amendments to Effluent Standards (addressing issues such as phosphorus control) and proposed revisions to Water Pollution Control Measures and Test Reporting Management Regulations (focusing on the test reporting of PFCs and pharmaceuticals).
