Abstracts
The concentrations of carbohydrates measured by gas chromatography in lakes of three different trophic levels have a tendancy to be lower than those measured by spectrophotometry. The concentrations of glucose and galactose were high in the euphotic zone of eutrophic lakes and the rhamnose was relatively high in the profundal zone. The ratio of the concentrations of each monosaccharide was relatively uniform from surface to bottom in a dystrophic lake. Glucose and galactose freshly produced in the euphotic zone might well be easily decomposed.
