Introduction. Dissolved organic matter (DOM) consists of soluble organic materials derived from the partial decomposition of organic materials, including soil organic matter, plant residues, and soluble particles released by living organisms, including bacteria, algae, and plants.issolved organic matter also acts to sequester toxic metals from the environment and prevent them from harming biological organisms. However, decomposition of DOM by microorganisms can serve to release metals and nutrients to the environment.
