Dissolved inorganic carbon

Annual DOC and DIC fluxes in the Tanguro Ranch[1] watershed
Average annual flux of DOC and DIC in rainfall, throughfall, stemflow, overland flow, and stream flow.[2]

Dissolved inorganic carbon (DIC) is the sum of the aqueous species of inorganic carbon in a solution. Carbon compounds can be distinguished as either organic or inorganic, and as dissolved or particulate, depending on their composition. Organic carbon forms the backbone of key component of organic compounds such as – proteins, lipids, carbohydrates, and nucleic acids.

Inorganic carbon is found primarily in simple compounds such as carbon dioxide, carbonic acid, bicarbonate, and carbonate (CO2, H2CO3, HCO
3
, CO2−

respectively). Dissolved inorganic carbon (DIC) includes three major aqueous species, CO2, HCO
3
,CO2−
3
, and to a lesser extent their complexes in solution with metal ions.[3]
