摘要：

The results of an investigation of stagnant water in a fjord basin have been compared with results obtained from the analysis of bottom water in a closed plexiglass box. It is found that the release rates (in mmol m-2 day-1) for hydrogen sulfide, hydrogen carbonate ammonium and phosphate agree remarkably well. The main reactions involved are given and the low pH in anoxic waters as well as the decrease of pH in the box experiments are explained by oxygen consumption and corresponding increase in carbon dioxide (total carbonate). The solubility products for iron(II) sulfide in both waters also agree. © 1979.
