Summary of Public Comments Received on the Government of Canada’s Draft Screening Assessment Report on Pigment Orange 5 (CAS No. 3468-63-1)
Formal comments made during the 60-day public comment period that took place from August 23, 2008 to October 22, 2008 on the draft screening assessment report on Pigment Orange 5, a substance included in Batch 3 of substances to be addressed as part of the Chemicals Management Plan Challenge were provided by Reach for Unbleached Foundation.
A summary of comments and responses is included below, organized by topic:
- Persistence, Bioaccumulation and inherent Toxicity
| Topic | Comment | Response |
|---|---|---|
| Persistence, Bioaccumulation and inherent Toxicity | The Persistence and bioaccumulation assessment is limited by the lack of data. | The assessment is based on available information using the current state of the science. When used in bioaccumulation models, this predicts a low bioaccumulation/bioconcentration potential, therefore based on available information, Pigment Orange 5 is not bioaccumulative. Pigment Orange 5 is relatively inert and has a low potential for biodegradation. In general, pigments are designed to be persistent. |
