Ethanol, 2,2'-[[4-[(2,6-dibromo-4-nitrophenyl)azo]phenyl]imino]bis-, diacetate (ester) (EDD)
CAS Registry Number 55619-18-6
What is it?
- Ethanol, 2,2'-[[4-[(2,6-dibromo-4-nitrophenyl)azo]phenyl]imino]bis-, diacetate (ester), also known as EDD, is an industrial chemical.
How is it used?
- EDD has previously been reported to be used as a colorant dye.
- Small quantities of EDD are believed to be in commerce; however, there is no recent information on manufacturing, importation or use of this substance.
Why did the Government of Canada assess it?
- Prior to assessment, EDD was identified as a potential concern to the environment based on information regarding possible persistence, accumulation in organisms and potential to cause harm to organisms.
How is it released to the environment?
- EDD may be released to the environment during industrial processes and consumer use.
- Upon its release, most of the substance is expected to end up in solid waste disposal sites. A significant proportion is also estimated to be released to sewer water.
- EDD may remain in the environment for a long time when released. However, data suggests that the substance does not significantly accumulate in or directly harm organisms.
What are the results of the assessment?
- The Government of Canada has conducted a science-based evaluation of EDD called a screening assessment.
- Results of the final assessment indicate that although EDD may remain in the environment for a long time, the substance is not expected to accumulate in organisms.
- Furthermore, the amount of EDD that may be released to the environment is below the level expected to cause harm to organisms.
- The Government of Canada has therefore determined that EDD is not entering the environment in a quantity or under conditions that constitute a danger to the environment.
What is the Government of Canada doing?
- Based on the conclusion of the final screening assessment, no further action is required for this substance.
- The final screening assessment was published on August 22, 2009.
What could Canadians do?
- Since EDD is not presently a concern for the environment or human health, Canadians do not currently need to take any specific actions with respect to this chemical.
