Castro & Belser, 1985, was awarded the reliability score of 2 according to the criteria of Klimisch et al, 1997. Castro & Belser, 1985, was therefore considered to adequately address this endpoint.
Castro & Belser, 1985, was conducted in a similar manner to the draft
OECD Phototransformation of Chemicals in Water - Direct and Indirect
Photolysis guideline. The study was performed in freshwater at 22 ºC for
a period of 2 hours. Extrapolated DT50 values were 380 days in roof
sunlight and 7.6 minutes under artificial light (450 -W medium-pressure
mercury lamp) with 10% degradation at 53 days under roof sunlight.
