What is it?
- Acid Green 40:1 is a dye.
How is it used?
- Acid Green 40:1 is a green dye used in the textile industry.
- Based on the most recent data available, Acid Green 40:1 is not in commerce in Canada.
Why did the Government of Canada assess It?
- Acid Green 40:1 was identified as a potential concern to the environment based on available information regarding possible persistence, accumulation and potential to cause harm to the environment.
What is the Government of Canada doing?
- The Government of Canada has conducted an evaluation of Acid Green 40:1 based on science, called a screening assessment.
- The evaluation showed that Acid Green 40:1 can stay in the environment for a long time. It can build up in the bodies of animals or within the food chain, and small amounts of Acid Green 40:1 can harm animals or plants that live in water.
- However, the Government of Canada has reviewed information that indicates Acid Green 40:1 is not currently in commerce in Canada in significant quantities.
- As a result, it is unlikely that Acid Green 40:1 is entering the environment as a result of commercial manufacture or use in this country.
- The Government of Canada has implemented a Significant New Activity or SNAc provision for Acid Green 40:1 since it has the potential to cause harm in the environment. This requires that any proposed new uses of Acid Green 40:1 must be reassessed prior to the substance being manufactured in or brought into Canada.
- The final screening assessment report was published on January 31, 2009.
