Phototransformation in air
Administrative data
Link to relevant study record(s)
- Endpoint:
- phototransformation in air
- Type of information:
- (Q)SAR
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: Accepted QSAR
- Principles of method if other than guideline:
- QSAR AOPWin v1.92
- Estimation method (if used):
- PHOTOCHEMICAL REACTION WITH OH RADICALS
- Concentration of OH radicals: 0.5E6 OH/cm3
- OH rate constant: 63.3681 E-12 cm3/molecule-sec
- Temperature for which rate constant was calculated: 25 deg C
- 24-hr day
- Computer programme: AopWin v1.92 - DT50:
- 6.076 h
- Conclusions:
- Using the QSAR AOPWin v1.92 tool, the half-life (DT50) of ethylenediamine in air is 6.076 h.
- Executive summary:
A study was conducted to determine the phototransformation of ethylenediamine in air. The rate constant for elimination via hydroxyl radical reaction in atmosphere can be estimated to 63.3681 E-12 cm3/ (molecule*sec) corresponding to a half life of 6 h, using the AOPWin (EPA, 2008).
