A simple inverse relationship between trace metal residence time and particle flux through the water column is tested on the trace metals Zn 2+ in freshwater and Th(IV) in ocean water systems with available data on the vertical flux and concentration of particulate matter and of Zn 2+ in lakes or on the disequilibrium of U/Th nuclides in the ocean. Natural or model aquatic ecosystems with different chemical compositions and particle fluxes confirm the concept that the particle flux through the water column is the major factor regulating trace metal concentrations in natural waters.
