Additional information

The reference substance BisP-IOTD was investigated for ready biodegradability in a closed bottle test according to OECD method 301D. The relative biodegradation values calculated from the O2 measurements performed during the test period of 28 days revealed no signficant biodegradation of BisP-IOTD at both concentrations tested (1 mg/l and 3 mg/l). In the toxicity control, BisP-IOTD was found not to inhibit microbial activity.

In conclusion, BisP-IOTD is designated as not readily biodegradable.

No further studies on biodegradation are available and not required at the tonnage band of 1 - 10 T/a.
