Applicant's summary and conclusion
- Conclusions:
- The PBT Profiler & EPI Suite has estimated that 1, 4-bis(mesitylamino)anthraquinone is expected to be found predominantly in soil and its persistence estimate is based on its transformation in this medium. Its half-life in soil, 360 days (8640 hrs). exceeds the threshold of 120 days as per Annex XIII of REACH.Therefore,1, 4-bis(mesitylamino)anthraquinone is estimated to be persistent in the soil environment.
- Executive summary:
The PBT Profiler & EPI Suite has estimated that 1, 4-bis(mesitylamino)anthraquinone is expected to be found predominantly in soil and its persistence estimate is based on its transformation in this medium. Its half-life in soil, 360 days (8640 hrs). exceeds the threshold of 120 days as per Annex XIII of REACH.Therefore,1, 4-bis(mesitylamino)anthraquinone is estimated to be persistent in the soil environment.
