Outline
With the frequent detection of emerging pollutants (EPs) at typical industrial sites, increasing attention has been directed toward their migration and exposure behaviors within soil-groundwater systems. This study focuses on the urgent need for localized construction of exposure assessment models in China. Drawing upon current practices in site management and simulation, it identifies key obstacles in data acquisition, parameter applicability, and methodological integration. On this basis, the paper systematically reviews existing contaminant transport models in both unsaturated and saturated zones, comparing their applicability with respect to process representation, spatial scale, and coupling capacity. It further explores recent trends in model integration and intelligent development, particularly the potential value of combining physics-based mechanisms with data-driven approaches. In light of China's complex geological and contamination conditions, the study proposes a technical pathway for advancing exposure model development. It emphasizes the importance of standardized scenario construction, localization of environmental parameter databases, and integrated platform development, aiming to enhance both the scientific robustness and practical applicability of exposure simulations and to support the establishment of a risk management framework for emerging pollutants.
