Phototransformation in air
Administrative data
- Endpoint:
- phototransformation in air
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: GLP status not known, guideline not known, published in peer reviewed literature, acceptable with restrictions
- Justification for type of information:
- A discussion and report on the read across strategy is given as an attachment in Section 13.
Cross-reference
- Reason / purpose for cross-reference:
- read-across: supporting information
Reference
- Endpoint:
- phototransformation in air
- Type of information:
- read-across based on grouping of substances (category approach)
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: GLP status not known, guideline not known, published in peer reviewed literature, acceptable with restrictions
- Justification for type of information:
- A discussion and report on the read across strategy is given as an attachment in Section 13.
- Reason / purpose for cross-reference:
- read-across source
- Principles of method if other than guideline:
- The author used data from other investigators. These data were generated using two methods: absolute and relative constant techniques. The author then applied a least squares analysis of degradation rate constants for organic chemicals by hydroxyl radicals developed by other investigators.
- GLP compliance:
- not specified
- Estimation method (if used):
- The rate constants were taken from experiments using relative constant techniques.
- DT50:
- 10.2 h
- Test condition:
- Author reports a recommended rate constant of 3.75E-11 cm3 molecule-1sec-1. Half life is calculated based on this rate constant and a hydroxyl radical concentration of 5E5 molecule.cm-3.
- Validity criteria fulfilled:
- not applicable
- Conclusions:
- The estimated half life of 1-hexene is 10.2 hours based on a recommended reaction rate with hydroxyl radicals and the concentration of hydroxyl radicals recommended in the Technical Guidance Document (2003).
- Executive summary:
Measured data from the author and other investigators were quality assessed and then used to develop rate constants for different chemicals. Therefore, this value represents a valid rate constant for 1 -hexene based on all valid studies at the time of publication.
