3.2 The fate of sulphide in wetlands 3.2.1 Emission of H2S to the atmosphere As an end product of dissimilatory sulphate reduction and protein degradation, hydrogen sulphide normally exists in the pore water of wetlands in three forms as un-ionized (H2S), singly (HS−) and doubly ionized ...
In these dominantly biogenic sediments, iron may become limiting; the degree of pyritization is very high (>80%) and values tend to be constant. Plots of either total or reactive iron versus total sulfur generally result in a linear relationship. In these low iron sediments, pore-water H2S ...
