Water Quality Criteria for Disperse Red 9
OAK RIDGE NATIONAL LAB TN
Pagination or Media Count:
The available data on the environmental fate, aquatic toxicity, and mammalian toxicity of Disperse Red 9 1-methylaminoanthraquinone, an organic dye used in pyrotechnic smoke signals, were reviewed. The USEPA guidelines were used in an attempt to generate water quality criteria for the protection of aquatic life and its uses and of human health. No data are available concerning the toxic effects of Disperse Red 9 on aquatic organisms therefore, a Criterion Maximum Concentration and a Criterion Continuous Concentration cannot be calculated. Toxicity studies following the USEPA guidelines are recommended. Because non-threshold and threshold toxicity data were insufficient, a water quality criterion for the protection of human health could not be calculated according to the USEPA guidelines.
