Review of spatially environmental multimedia fate models of emerging pollutants in the context of land and sea coordination

The control and risk prevention of emerging pollutants is a major national demand, and the environmental exposure of the pollutants should be assessed. However, using environmental monitoring methods to evaluate large-scale regional pollution characteristics requires high cost, and it is difficult to reflect the environmental fate of the pollutants comprehensively and systematically. Environmental multimedia fate model can accurately describe the migration, transformation and environmental trend of the emerging pollutants, and it is an effective tool for environmental risk assessment of new pollutants. Compared with traditional environmental multimedia fate model, spatially environmental multimedia fate model has the advantages of high resolution, high precision, and it can exhibit the spatial difference of the pollutant distribution. The ocean is an important sink for the emerging pollutants, so it is imperative to construct an environmental multi-media model integrating land and sea. In this paper, the current spatially environmental multimedia fate models for environmental exposure assessment of the emerging pollutants are summarized, and the model construction methods, relevant parameters acquisition and future research prospects are reviewed.
