Results and discussion
% Degradation
- Key result
- Soil No.:

- % Degr.:
- 50
- Parameter:
- test mat. analysis
- Sampling time:
- 7 d
Half-life / dissipation time of parent compound
- Key result
- Soil No.:
- #1
- DT50:
- 7 d
- Type:
- (pseudo-)first order (= half-life)
- Remarks on result:
- other: DT90: = 191.4 day(s) mathematically extrapolated
- Transformation products:
- not specified
Any other information on results incl. tables
-
Microbial biomass: 48.0-51.6 mg/100 g at day 0; 24.0-30.8 mg/100 g soil
at the end of the test.
- No differentiation is possible whether abiotic or biotic degradation
has occurred, since no sterile control was performed.
-
As the DT90 value (191.4 d) is outside the range of the
test period (100 d), this value can only be regarded as an
order of magnitude.
Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
