LageCO2heimgebonden

LageCO2heimgebonden is a term found in some Dutch-language discussions to describe situations in which carbon dioxide is weakly bound to a host, such as minerals, organic matter, or biological sites. The expression is not part of standard, widely used nomenclature in carbon-cycle science, and its precise definition varies between sources. In soils, lage CO2 binding can indicate low capacity to form stable carbonate minerals or to incorporate CO2 into organic substrates, leading to more rapid CO2 fluxes to the atmosphere. In aqueous systems, it may refer to a predominance of dissolved CO2 over bicarbonate or carbonate species, resulting in higher volatility of CO2. In biology, it can describe environments or molecules with low affinity for CO2 binding, allowing faster release.

Measurement of lageCO2heimgebonden-like properties relies on understanding CO2 speciation and binding equilibria. Methods include calculating binding constants for carbonate formation, analyzing gas-solid or gas-liquid adsorption isotherms, and monitoring CO2 fluxes under controlled conditions. The concept is useful for discussing factors that limit carbon storage, such as mineralogy, pH, temperature, and organic-matter content, and for evaluating materials designed for CO2 capture and storage.

Critics argue for standard terminology to avoid ambiguity. LageCO2heimgebonden serves as a descriptive placeholder rather than a formal category. See also: carbon sequestration, carbonate chemistry, soil organic carbon, CO2 capture.
