| Data collection | It is unclear to what degree paper products have been tested to determine the presence of D & C Red No. 21. | Available information does not indicate that paper products have been tested for the presence of D & C Red No. 21. However D & C Red No. 21 was surveyed in 2001, and there were no companies indicating that it was used in paper products in a quantity meeting the 100kg reporting criteria. Furthermore no information on use in paper products was revealed by a recent search for information on international applications. Therefore, it is assumed that paper products are not a source of D & C Red No. 21 in Canada. The screening assessment report has been modified accordingly. |
| Releases to the Environment | Further analysis should be done on the presence of this chemical in printed and coated paper products that are imported into Canada, the disposal route for those paper products and the potential for this chemical to be entering the environment in significant volume through the land application of recycled pulp sludge. | A recent search of available information in other jurisdictions did not reveal that paper products are a major use for D & C Red No. 21, therefore it is not expected that imported paper products would be a source of D & C Red No 21. Therefore further analysis is not believed to be warranted. |
