Description of key information

Reactive Yellow 095 is a dark colored dye, which will lead to dark discoloration of the test medium. The discoloration may lead to reduced light intensity in the test medium, which will affect the growth of algae by hampering the photosynthesis process, thus making it difficult to differentiate the toxic effect from the effect of discoloration. Hence the toxicity study with algae and cyanobacteria was not considered, instead the toxicity study to aquatic plants was performed.
