BODIS in Seawater (PARCOM)
Biodegradability of Insoluble Substances (BODIS) in Seawater (PARCOM)
This method was developed for the assessment of degradation of poorly soluble materials in the marine environment, however, it can also be adpated for Freshwater purposes. The test vessels are closed glass bottles with a known volume of natural seawater (2/3) and air (1/3). They are shaken continuously to ensure steady state oxygen partitioning between liquid and gas phases. The degradation is followed by weekly measurements of the biochemical oxygen demand (BOD) in the aqueous phase for a 28 day period.
The BOD is calculated from the cumulative oxygen uptake.
