摘要：

Time dependent patterns of amino acid concentrations have been studied by HPLC for different lakes of the Berlin area, Data analysis has been performed by conventional principal component analysis as well as by its more recent N-way extension. It turns out that lakes mainly differ by their general amino acid production as a function of time and season, Apart from this, in a single case there occurs a specific pattern which might be related to an exterior influence, This pattern, although clearly detected, has been not stable over time, Measurements are reproducible with respect to time (comparison of two succeeding years) and to position (comparison of isolated parts of a lake).
