Persistence, Bioaccumulation and inherent ToxicityDespite a lack of information (e.g. monitoring concentrations, bioaccumulation and toxicity data), the screening assessment proposes that Pigment Red 4 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, Pigment Red 4 is not bioaccumulative. Pigment Red 4 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 Pigment Red 4 does not meet the criteria set out in section 64 of CEPA 1999.
