Background

Six substances were originally referred to under the Chemicals Management Plan as the Triazoles Group and the Cyanurates Group. These 2 groups have since been merged and are referred to collectively as the Triazines and Triazole Group. Two of these 6 substances were subsequently determined to be of low concern to both human health and the environment through another approach. Conclusions for CAS RNs 101-37-1 and 288-88-0 are provided in the Screening Assessment for 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. The other substance (CAS RN 121-82-4) will be assessed in a future screening assessment.
