TOC steps natural carbon but distinct organic and natural molecules will create different oxygen demand. Measuring TOC alone is not going to always show just how much oxygen is going to be consumed with the organics from the environment. One example is, oxalic acid and ethanol generate equivalent TOC results. Even so, as a consequence of distinct oxidation states, the oxygen demand of ethanol is six situations larger than oxalic acid, that means ethanol could have a higher impact on the dissolved oxygen articles of a receiving water.
