<md:comment>Measurements of nitrogen and carbon were performed in the laboratory of Geochemistry of Landscapes, Department of Geochemistry of Landscapes and Soil, Faculty of Geography, Lomonosov Moscow State University. Measurements were carried out on CHNS analyzer VARIO EL III V4.01 20.Aug. 2002, Elementar Analysen systeme GmbH, Germany. Sulfanilic acid (Merck) was used as a standard with values of N = 8.090%, C = 41.610%.</md:comment>
