An approximate biogenic contribution of minor elements to sapropel of Lake Kirek in West Siberia is estimated using the "model of direct inheritance" of their composition in plankton by OM of bottom sediments (Yudovich and Ketris, 1990). It is shown that the lifetime accumulation of P, Br, and Zn in copepod zooplankton of Lake Kirek notably affects the concentration of these elements in sapropelic mud (biogenic contribution is approximately 95-53%). The biogenic share of other elements in these sediments is substantially lower: approximately 30% for Sr and Ba; 26-16% for Ca, Pb, Cd, Cu, K, Mg, and Cr; and no more than 5% for As, Co, Fe, Ni, Ti, Y, and Mo. © 2011 Pleiades Publishing, Ltd.
