Date Activity
November 2019 Anticipated publication of the final screening assessment.
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 CAS RNs 6408-72-6, 14233-37-5, 17418-58-5, 72391-24-3, 74499-36-8) and the Risk Management Scope for Solvent Violet 13.

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 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 Screening Assessment for the Rapid Screening of Substances with Limited General Population Exposure.
