Type of information:
experimental study
Adequacy of study:
other information
Study period:
April 2008
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
guideline study without detailed documentation
Remarks:
OECD 308
Qualifier:
according to guideline
Guideline:
OECD Guideline 308 (Aerobic and Anaerobic Transformation in Aquatic Sediment Systems)
GLP compliance:
not specified
Details on results:
Mass Balance 100 ± 10%
There was no evidence of degradation in the water phase.
The dissipation half lives from the water phase were 222 and 95 days for the high and low organic matter vessels, respectively. There was very little evidence of degradation or dissipation in the sediment phase and specific sediment half-lives could not be calculated.
Validity criteria fulfilled:
not specified
Conclusions:
There was no evidence of degradation in the water phase.
The dissipation half lives from the water phase were 222 and 95 days for the high and low organic matter vessels, respectively. There was very little evidence of degradation or dissipation in the sediment phase and specific sediment half-lives could not be calculated.

Description of key information

There was no evidence of degradation in the water phase (OECD 308).

The dissipation half lives from the water phase were 222 and 95 days for the high and low organic matter vessels, respectively. There was very little evidence of degradation or dissipation in the sediment phase and specific sediment half-lives could not be calculated.

Key value for chemical safety assessment
