Emerging pollutants have drawn global concerns under rapid urbanization and industrialization. However, research has been relatively independent on specific groups of pollutants due to the limitation of the discipline. In this study, from the perspective of interdisciplinary research, taking the fluorochemical industry as an example, two major categories of emerging pollutants, per-and polyfluoroalkyl substances (PFAS) and ozone-depleting substances (ODS), were discussed regarding their co-emission. The co-production mechanism of the two types of pollutants were discussed from the production processes to reveal their internal relationship; their differences and cross-processes in the emission routes were analyzed, as well as the technical approaches and challenges required in sample collection, pretreatment, and instrumental analysis. The eco-environmental effects, including ecological and human health risks, ozone depletion, and global warming effects caused by the two types of pollutants in different media were comprehensively summarized. We also further expanded the perspectives of stakeholder analysis, life cycle analysis, and mass balance analysis to provide suggestions for further research and management of emerging pollutant co-emissions.
