Abstract:
The nature and abundance of O₂ and organic compounds were examined in the streams of the Marmot basin. Levels of dissolved O₂ in mountain streams of the Marmot basin averaged 11,000 µg/liter. The streams were 90–105% saturated with dissolved 02. Biochemical and chemical demand averaged 2,000 and 4,000 µg/liter, respectively. Total organic C in mountain streams averaged 4,000 µg/liter. Analyzed organic compounds in stream waters constituted 25% of the total organic C, refractory compounds accounted for 23%, and labile compounds 2%. Refractory organic compounds, humic and fulvic acids, averaged 790 µg/liter and tannins and lignins 100 µg/liter. Averages of labile compounds were: hydrocarbons, 0.05 µ/liter (sum of individual compounds in the range of C₁₄–C₃₂); phenols, 2 µg/liter; fatty acids, 2 µg/liter; carbohydrates, 45 µg/liter; and total amino acids, 10 µg/liter (sum of 16 protein amino acids). Seasonal variations in abundances of organic compounds were observed.
