Hydrochemical regime components of Lena water

The concentrations of particulate and dissolved organic matter and mineral nutrients in the Lena River and its major tributaries are analyzed. The concentrations of these components are shown to be nonuniform and feature wide variations under the effect of matter input by major tributaries. The tota...

Zusammenfassung:	The concentrations of particulate and dissolved organic matter and mineral nutrients in the Lena River and its major tributaries are analyzed. The concentrations of these components are shown to be nonuniform and feature wide variations under the effect of matter input by major tributaries. The total fluxes of matter increase downstream the river in agreement with increasing water runoff. The effect of delta in matter accumulation is considered. The organic matter in the Lena was found to be represented mostly by soil terrigenous material.
