This International Standard specifies six incubation systems for measuring the rates and extent of mineralization of organic compounds in soil by measurement of carbon dioxide evolution. All incubation systems are applicable to soluble or insoluble compounds but choice of system depends on the overall purposes of the study. This International Standard does not apply to the use of such systems for material balance studies, which are often test-substance specific. Mineralization is only one of the parameters which can be used to assess the biodegradation of organic compounds in soil. If mineralization is not extensive, this does not necessarily mean that the test material is not biodegradable. Material balance studies to assess the production of metabolites, in addition to mineralization studies, provide a comprehensive assessment of biodegradation. It is essential that this International Standard be used in conjunction with ISO 11266, which gives general guidance on the information needed to assess the potential of an organic compound to be degraded in soil. Depending on the aim of the study, it is feasible to use a range of incubation conditions, described be1ow, and different methods of analysis.
