Applicant's summary and conclusion
- Conclusions:
- Half life period of Acid violet 43 in water is observed to be 60 days (1440 hrs.) while in sediment it is 541.6 days (13000 hrs). Based on these half life values of Acid violet 43, it is concluded that the chemical is not persistent in water and persistent in sediment.
- Executive summary:
Half life period of Acid violet 43 in water is observed to be 60 days (1440 hrs.) while in sediment it is 541.6 days (13000 hrs). Based on these half life values of Acid violet 43, it is concluded that the chemical is not persistent in water and persistent in sediment.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
