A rapid and simple method for estimating sulfate reduction activity and quantifying inorganic sulfides

Volume, 63, no. 4, p. 1627-1630. After publication of this article, it was brought to the attention of the authors that an earlier paper, similar in both methodology and salient findings to ours, was published by Y. P. Hsieh and C. H. Yang. Both papers describe a diffusion method for the extraction and recovery of reduced inorganic sulfides from sediment samples placed in sealed reaction vessels. Our paper describes the application of the method to the measurement of sulfate reduction rates. The earlier work contains important information, but unfortunately, the existence of the work was realized only after publication of our paper. We regret this omission, and the following reference should have been cited in our article. 13a.Hsieh, Y. P., and C. H. Yang. 1989.
