Triazines and Triazole Group
|Substance group||CAS RN||Common name||DSL name||Final screening assessment||Conclusion on section 64 criteria||Follow-up activities|
|Triazines and Triazole Group||61-82-5||Amitrole||1H-1,2,4-Triazol-3-amine||HTML||Do not meet||None planned at this time|
|2893-78-9||Sodium dichloroisocyanurate (NaDCC)||1,3,5-Triazine-2,4,6(1H,3H,5H)-trione, 1,3-dichloro-, sodium salt|
Although a risk to human health or the environment has not been identified at current levels of exposure, there may be a concern if exposures to amitrole or to hexa(methoxymethyl)melamine were to increase. As a result, these substances may be considered in future initiatives to track their commercial status or identify new uses.
|July 3, 2020||Publication of the final screening assessment. The related notice was published in the Canada Gazette, Part I: Vol. 155, No. 27.|
|April 13, 2019||Publication and start of 60-day public comment period on the draft screening assessment (including follow-up activities for CAS RNs 61-82-5 and 3089-11-0). The related notice was published in the Canada Gazette, Part I: Vol. 153, No. 15.|
Six substances were originally referred to under the Chemicals Management Plan as belonging to the Triazoles Group or the Cyanurates Group. Three substances from the 2 groups have since been merged and are referred to collectively as the Triazines and Triazole Group. Two of the other substances were subsequently determined to be of low concern to both human health and the environment through other approaches. Conclusions for CAS RNs 101-37-1 and 288-88-0 are provided in the Final 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.
