Description of key information

Additional information

In the upper layers of surface waters degradation of 1,2-dichlorobenzene can occur due to indirect photolysis. Degradation by hydrolysis under environmental conditions is unlikely to occur.

In the atmosphere, photodegradation takes place by reaction with photochemically produced OH radicals. The half-life is calculated from a measured rate constant to be 38 days.
