Annex A (informative) Examples of biodegradation curves

Restricted to the description of the four techniques for introducing the poorly-soluble organic test compounds for a subsequent test on biodegradability in an aqueous medium. The techniques are: direct addition, which is restricted to non-volatile compounds, ultrasonic dispersion of non-volatile liquid and solid compounds, adsorption on an inert support and dispersions or emulsions with an emulsifying agent. Volatile chemicals may not be tested.
