The notified chemical had no acute effect on various trophic levels tested up to its solubility limit under the strict test conditions. For the details of the environmental effect studies please refer to Appendix C. 7.2.1 Predicted No-Effect Concentration Based on the results of the ecotoxicological testing the Predicted No-Effect Concentration has been calculated as follows: 7.3. Environmental risk assessment Without a PEC, it is not possible to derive a Risk Quotient. The only environmental release expected throughout the life cycle of the notified chemical under the proposed use pattern is through disposal to landfill. In landfill, the notified chemical is expected to be immobile, and overtime degrade to simple organic and nitrogen based compounds. Should the notified chemical be disposed of by incineration, it is expected to be thermally decomposed to form various oxides of carbon and nitrogen and water. While the notified chemical was found to be slightly bioconcentrating, this is not expected to pose a risk to the environment as release to the aquatic environment is not expected. Therefore, the notified chemical is not expected to pose an unacceptable risk to the aquatic environment. 8. CONCLUSIONS SUMMARY OF RISK ASSESSMENT FOR THE ENVIRONMENT AND – HUMAN HEALTH 8.1. Hazard classification Based on the available data the notified chemical is not classified as hazardous under the (NOHSC, 2004). Approved Criteria for Classifying Hazardous Substances 8.2. health risk assessment 8.2.1. Occupational health and safety Under the conditions of the occupational settings described, the risk to workers is considered to be acceptable. 8.2.2. Public health When used in the proposed manner the risk to the public is considered to be acceptable. 8.3. Environmental risk assessment The chemical is not considered to pose a risk to the environment based on its reported use pattern. 9. MATERIAL SAFETY SHEET The MSDS of products containing the notified chemical provided by the notifier was reviewed by NICNAS and is published here as a matter of public record. The accuracy of the information on the MSDS remains the responsibility of the applicant. The MSDS was to be in accordance with the National Code of Practice for the Preparation of Material Safety Data (NOHSC, 2003). Sheets 10. RECOMMENDATIONS
