Assessing the natural component of the external load
due to organic matter and biogenic elements
on the water bodies in Northwestern Russia

S.A. Kondratiev, G.A. Alyabina, and I.N. Sorokin

We suggest the method to calculate the natural component of the external loads due to organic matter and biogenic elements on the unexplored lakes using the values of the moduli of removal for these elements, and indices of the lakes’ specific catchments. The schematic map has been generated for the distribution of natural moduli of removal on the catchment of the Gulf of Finland. We calculated the external natural loads for 94 lakes in landscapes with a high percentage of lakes.
