Sediment in sewers contain many kinds of components such as sulfuric acid and sodium sulfide from treatment plants as well as amino acids from food processing plants.

It is easy for sulfuric acid and sodium sulfide to produce hydrogen sulfide (H2S). In addition, the characteristic of these gases to breath oxygen in air also induces an oxygen deficiency.
