摘要：

Dissolved inorganic carbon (DIC) accumulates in the medium during the Sturm test for ready biodegradability, indicating that CO2 produced by metabolism is not physically removed efficiently. Thus, the time taken to reach the pass levels is greater for CO2 collection than for dissolved organic carbon (DOC) removal, sometimes leading to a pass for DOC removal but not for CO2 collection in the 10-day window (the 10 days following commencement of degradation). Remedies are the abolition of the 10-day window restriction or the simultaneous determination of DIC and CO2 trapped. Other test methods for measuring CO2 production are indicated.
