Follow-up activities

Although a risk to human health or the environment has not been identified at current levels of exposure, there may be a concern if exposure to Solvent Violet 59, Solvent Blue 36, Disperse Red 60, Acid Blue 239, and CAS RN 74499-36-8 were to increase. As a result, these substances may be considered in future initiatives to track their commercial status or identify new uses.

Date Activity
October 1, 2022 Publication in the Canada Gazette, Part I, Vol. 156. No. 40 of a proposed order adding Solvent Violet 13 to Schedule 1 to the Canadian Environmental Protection Act, 1999, and start of a 60-day public comment period.
July 17, 2021 Publication of the Final Screening Assessment for the Anthraquinones Group. The Risk Management Approach for Solvent Violet 13 was also published for a 60-day public comment period. The related notice was published in the Canada Gazette, Part I, Vol. 155, No. 29.
November 3, 2018 Publication and start of 60-day public comment period on the Draft Screening Assessment for the Anthraquinones Group (including follow-up activities for Solvent Violet 59, Solvent Blue 36, Disperse Red 60, Acid Blue 239, and CAS RN 74499-36-8) and the Risk Management Scope for Solvent Violet 13. The related notice was published in the Canada Gazette, Part I: Vol. 152, No. 44.


Eight other substances, CAS RNs 2475-45-8, 4051-63-2, 13676-91-0, 19286-75-0, 2379-79-5, 15791-78-3, 19720-45-7 and 28173-59-3, were identified as being part of the Anthraquinones Group at the outset of the third phase of the CMP. These substances were subsequently determined to be of low concern to both human health and the environment, through other approaches. Conclusions for CAS RNs 2379-79-5, 15791-78-3, 19720-45-7 and 28173-59-3 are provided in the Final Screening Assessment of Substances Identified as Being of Low Concern using the Ecological Risk Classification of Organic Substances and the Threshold of Toxicological Concern (TTC)-based Approach for Certain Substances. Conclusions for CAS RNs 2475-45-8, 4051-63-2, 13676-91-0 and 19286-75-0 are provided in the Final Screening Assessment for the Rapid Screening of Substances with Limited General Population Exposure.
