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.
