Similarly, hydrogenous sediments can have high concentrations in specific locations, but these regions are very small on a global scale. It disturbs and damages the habitats of the oceanic species and also disturbs the food chain. However, sedimentation rates near the mouths of large rivers with high discharge can be orders of magnitude higher. 2HgO(s)2Hg(l)+O2(g)2 \mathrm{HgO}(s) \rightleftharpoons 2 \mathrm{Hg}(l)+\mathrm{O}_2(g)2HgO(s)2Hg(l)+O2(g).
