Description of key information

Zinc bis dimethyldithiocarbamate is susceptile to indirect photodegradation in air (half-life = 2.8 h)

Key value for chemical safety assessment

Additional information

The dissipation half-life of zinc bis dimethyldithiocarbamate (CAS No. 137-30-4) in air was calculated using the AOPWIN subroutine from EPISuite™ computer program (US EPA). This substance degrades rapidly in the atmosphere (half-life = 2.8 hours).
