Abstract： Suspended particulate matter （SPM）， as a key carrier of heavy metals in aquatic systems， regulates the solid-liquid partitioning of heavy metals through adsorption and flocculation mediated by its inorganic， biological， and organic components. The composition characteristics of SPM，the adsorption-desorption mechanisms of heavy metals on SPM， as well as the chemical speciation and physical fractionation laws have been reviewed. The hydroxyl and carboxyl functional groups on the SPM surface play a dominant role in the environmental behavior of heavy metals through surface complexation and ion exchange has been revealed. Further， the disturbance mechanism of climate change on the dynamic balance of heavy metals in SPM was discussed： the composition evolution of SPM and the changes in water body physical and chemical properties can alter the existing forms of heavy metals， thereby affecting their ecological risks. Future research should integrate artificial intelligence and multi-source data technologies to quantify the cumulative effects of extreme climate events，enhance the precision of risk prediction and provide scientific support for aquatic environment security.
