Résumé :	Concentrations of Al, Mn, Fe, Ag, and Pb in dissolved and particulate phases of the surface water were determined at 15 stations along the coastline off western Taiwan in April of 2007. This study presents the first set of data for Al, Ag, and Pb in the nearshore waters. Latitudinal distribution of these metals showed that high values were present in the regions affected by high fluvial discharge from the Dan-Sui River and the Cho-Sui River. Using the particle fluxes from Po-210/Pb-210 disequilibria, the removal fluxes and the residence times of the trace metals were calculated. Based on the K (d) values, the sequence of particle affinity of trace metals, Fe similar to Al >> Pb > Mn > Ag, was found. The correlation of the residence times and of the partitioning coefficients of multiple metals in the nearshore waters implies that the affinities to the particles determine the geochemical cycling of metals in the coastal water.
