Model tests on volatilization of organic trace substances in surfaces waters
Organic trace substances released to surface waters are usually in the three-phase system of water/ suspended matter/air. Transition into the vapour phase is first investigated with the aid of a model in a closed system, then in an open system. The distribution coefficient of the closed system can be correlated with a defined “loss rate” of the respective compound in the open system. The k-values from 1 to > 107 are discussed in their relevance to analytics. In addition, attempts have been made to transfer the model results to flowing waters.
