Administrative data

Endpoint:
phototransformation in air
Type of information:
calculation (if not (Q)SAR)
Remarks:
Migrated phrase: estimated by calculation
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Results were obtained with a reliable software based on the representative individual components of the UVCB substance, which however can not be considered as reliable as an experimental result for the substance.

Type:
Constituent
Details on test material:
SMILES: not relevant (UVCB substance). Range of atmospheric half life values for the substance was estimated based on the respresentative individual
structures of the relevant hydrocarbon blocks according to the available analytical information.

Study design

Estimation method (if used):
Estimated by calculation (HCBIOWIN 4.00)

Results and discussion

Dissipation half-life of parent compound
DT50:
>= 1.5 - <= 66 h
Test condition:
Estimated by calculation (half-life in air)

Any other information on results incl. tables
