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
