Description of key information

The degradation rate constant for the environmentally relevant constituent of the UVCB test item was calculated to be 43.4903 x 10E-12 cm3/molecule-sec and the hydroxyl radical reaction half-life was estimated as 2.951 hours based on 12 hours of daylight (EPISUITE AOPWIN v1.92).

Key value for chemical safety assessment

Additional information

EPISUITE (AOPWIN v1.92) was used to calculate the hydroxyl radical reaction half-life for the environmentally relevant constituent of the UVCB substance. The degradation rate constant was 43.4903 x 10E-12 cm3/molecule-sec and half-life was estimated to be 2.951 hours based on a 12-hour day.
