Under the test conditions the percentage biodegradation of1,2 -
Dichloropropanereached a mean of 11.7 % after 28 days based on its ThODNH4.
The test item can therefore be considered to be not ready
biodegradable.According to the test guidelines the pass
level for ready biodegradability is removal of 60 % ThOD.
The reference item Sodium benzoate was sufficiently degraded to a
mean of 83.3 % after 14 days, and to a mean of 90.0 % after 28 days of
incubation, based on ThODNH4, thus confirming the suitability
of the used activated sludge inoculum.
In the toxicity control containing both, the test item and the
reference item Sodium benzoate, a mean of 40.1 % biodegradation was
noted within 14 days and 43.7 % biodegradation after 28 days of
