Beschreibungen/Notizen

• Radiochemical techniques were used to monitor the short-term exchange of phosphorus between soluble and particulate fractions in the water during enrichment experiments in a South African impoundment. Tracer uptake kinetics were examined under a range of conditions in the water, created by the use of a series of isolation columns. Labeled soluble fractions were separated by gel filtration and their exchange with the particulate fraction and with intact sediment cores were examined independently. Only two distinct soluble fractions were evident using the radiotracer method and their exchange characteristics with suspended particulate material and intact sediment cores differed markedly. Radiotracer partitioning contrasted with the phosphorus partitioning measured with standard chemical methods.
