TopicCommentResponse
Releases to the EnvironmentThere is a lack of information on the amount of Disperse Red 86 imported into Canada and any potential releases from such products. There is a lack of environmental monitoring concentrations in Canada for Disperse Red 86.The assessment is based on available information using the current state of the science and the resulting modelled environmental concentrations were estimated conservatively – to ensure that potential for exposure is not underestimated. There is a possibility that this substance may be included in future monitoring programs.
Persistence, Bioaccumulation and inherent ToxicityDespite a lack of information (e.g. monitoring concentrations, bioaccumulation and toxicity data), the screening assessment proposes that Disperse Red 86 does not meet the criteria in section 64 of CEPA 1999.The assessment is based on available information using the current state of the science. Based on available information, Disperse Red 86 is not bioaccumulative. Disperse Red 86 is relatively inert and has a low potential for biodegradation. In general, pigments are designed to be persistent. The risk assessment therefore leads to a conclusion that Disperse Red 86 does not meet the criteria set out in section 64 of CEPA 1999.
