Phototransformation in water
Administrative data
Link to relevant study record(s)
- Endpoint:
- phototransformation in water
- Type of information:
- experimental study
- Adequacy of study:
- disregarded due to major methodological deficiencies
- Study period:
- 1998
- Reliability:
- 4 (not assignable)
- Rationale for reliability incl. deficiencies:
- documentation insufficient for assessment
- Study type:
- direct photolysis
- Qualifier:
- no guideline followed
- GLP compliance:
- no
- Analytical method:
- high-performance liquid chromatography
- Light source:
- other: Rayonet RPR-208 merry-go-round photoreactor
- Quantum yield (for direct photolysis):
- 1.22
- Conclusions:
- In a test on photodegradation in aqueous solution, the quantum yield was determined to logY = 0.085. As no degradation half-life in the environment was derived, the study is not useful for the exposure assessment and is therefore disregarded.
- Endpoint:
- phototransformation in water
- Type of information:
- experimental study
- Adequacy of study:
- disregarded due to major methodological deficiencies
- Study period:
- 1996
- Reliability:
- 4 (not assignable)
- Rationale for reliability incl. deficiencies:
- documentation insufficient for assessment
- Qualifier:
- no guideline followed
- GLP compliance:
- no
- Specific details on test material used for the study:
- Name in the publication: p-An-Cl
obtained from Aldrich (highest purity available) - Rate constant (for indirect photolysis):
- 760 other: /min
- Conclusions:
- In a test on photodegradation with TiO2 as catalyst, a first-order rate constant of 760/min was determined.
As no degradation half-life in the environment was derived, the study is not useful for the exposure
assessment and is therefore disregarded.

Result reported in the publication: logY = 0.085
Description of key information
In a test on photodegradation in aqueous solution, the quantum yield was determined to logY = 0.085.
In a further test on photodegradation with TiO2 as catalyst, a first-order rate constant of 760/min was determined.
As no degradation half-life in the environment was derived, both studies are not useful for the exposure assessment and are therefore disregarded.
Key value for chemical safety assessment
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
