Oxygen required in biological stabilization of organic materials is a fundamental approach in assaying the presence of such biodegradable materials. Comparative results present the status of biological stabilization reactions in natural systems and biological processes. The bio-chemical oxygen demand procedure (5-day incubation) has been utilized as a limited measurement of the desired data. A stabilization oxygen demand technique for more definitive examination of biological stabilization is being developed by a Task of Committee D—19 on Water. The analytical technique is based on measurements of energy oxygen utilized in support of synthesis reactions and of the resulting synthesis of microorganisms. Completion of analysis in about 1 h is an objective.
