Description of key information

The test material is a coloured dye which when mixed in test medium will give a coloured test medium. Due to light absorption, coloured substances such as dyes can inhibit algal growth, which is not the result of a toxic action. This shading effect can confound measures of chemical toxicity and thus impair the risk assessment. In an effort to avoid this problem, a Lemna minor (Duckweed) Growth Inhibition test (static) was conducted instead.
