Summary of Public Comments Received on the Substance 1,2-Dibromoethane Government of Canada Draft Screening Assessment Report
Comments on the draft Screening Assessment Report (SAR) were provided by the European Chemicals Agency and the United Kingdom, via the OECD Cooperative Chemicals Assessment Programme.
A summary of comments and responses is included below.
| Topic | Comment | Response |
|---|---|---|
| Inherent Toxicity | There needs to be clarification on interpretation of data from Hawkins et al. 1998. | The SAR has been revised to clarify how the No Observed Effect Concentration (NOEC) and the Lowest Observed Effect Concentration (LOEC) were determined from Hawkins et al. 1998. |
| A Robust Study Summary is required for Hawkins et al. 1998, as this study forms the basis for the Predicted No-Effect Concentration (PNEC) derivation in the report. | A Robust Study Summary has been developed and added into Appendix 1 in the SAR. | |
It would be worthwhile to mention that no reliable data on aquatic algae were identified.

The SAR has been revised to address the comment. |
