Risk Assessment


Health assessment conclusions for the 33 azo basic dyes and 16 aromatic amines are supported. In particular, that these substances are not released to the environment in amounts that pose a danger to human and ecosystem health; and are not expected to bioaccumulate.Noted.
Information gatheringThe partnership for sharing information between industry and the Chemicals Management Plan (CMP) program was viewed as positive throughout the CMP evaluation process for benzidine-based substances.Noted.



Industry support is being offered to find options for identifying and managing future risks related to changes in use and exposure - including the tracking of new international activities that could impact Canadians.Stakeholders are encouraged to participate and provide feedback at all stages of the risk assessment and management process.  A consultation document on potential options for information gathering or preventative actions will be available for stakeholder feedback after assessment of all substances in the Aromatic Azo and Benzidine-based Substance Grouping are completed.
