Importance of lacustrine physical factors for the distribution of anthropogenic 60-Co in Lake Biel
Article Abstract:
The depth of intrusion of the Aare River into Lake Biel, Switzerland, affects the fate of radionuclides in the lake, both average residence time and biochemical environment. Tracer experiments with cobalt 60 released into the Aare from the Muhleberg nuclear power plant have confirmed the validity of the intrusion model. Scavenging increases in the winter, when the Aare water is denser and intrudes farther into the lake. The radionuclides stay longer in the lake and there is more time for scavenging in the winter, even though particle concentrations are elevated in the summer.

High spatial resolution measurements in lake sediments with PVC based liquid membrane ion-selective electrodes
Article Abstract:
Ion-selective PVC liquid membrane minielectrodes have been designed for measurement of pH, CA2+, CO2-/3, NH4+, NO3-, and NO2-. Applicability to measurement of concentration gradients in lake sediments is shown.
