River water samples were collected ten times during a 24-month period at 16 stations in the Raane, Toere, Kalix and Torne rivers in northern Sweden. Silicon, Al, Mn, Fe, Ca, Mg, Na, Ba and Sr were measured in the aqueous phase and in addition Cu, Ni, Zr, Cr, Zn and V were determined in the suspended fraction. This report is restricted to six stations in the Kalix River. Silicon, Ca, Mg, Na, Sr and Ba are predominantly transported in dissolved phase, whereas most of the Fe and Al are in the suspended fraction. Mn is almost equally distributed between the phases. The annual run off from the Kalix River to the Bothnian Bay shows very high concentrations of Fe and Mn in the suspended matter. Furthermore, this fraction consists of at least four independent phases. Fe and Mn are not correlated and Mn might be of biogeochemical origin.
