Description of key information

A half-life of 2.9 to 3.1 h indicates that Diuron will disappear rapidly in air

Key value for chemical safety assessment

Additional information

In order to determine the atmospheric half-life of Diuron, a calculation based on the Atkinson estimation method was used and the Atmospheric Oxidative Program was also used (hellpointner, 1991). A half-life was determined of 2.9 to 3.1 h indicating a rapid disappearance on Diuron in air.
