Additional information

The endpoint “phototransformation in soil” is not a data requirement for the registered substance. However, for the sake of completeness this endpoint is covered by a short summary of the available data. There are a total of three studies on the phototransformation in soil available.


Two studies on the photodegradation of 2,6-dibromo-4-cyanophenyl octanoate were performed according to the US EPA Subdivision N, 161-3 guideline and GLP. The first study assessed the photodegradation on thin layers (about 2 mm) of a sandy silt loam soil using light irradiation over the range 300-800 nm (353 Wh/sqm). The second study used thin layers (about 2 mm) of a sandy loam soil exposed to an artificial sunlight intensity of 544.0 Watts/sqm at 25 °C. The half-life of the test substance was calculated to 2.2 and 2.6 days, respectively.


A third study, confirmed the identity of the test substance and its metabolites that were formed during a soil photolysis study.
