Description of key information

The test material FAT 41001 is a dark colored dye which when mixed in test medium will impart dark color. Due to light absorption, colored 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 Lemna gibba (Duckweed) Growth Inhibition test (static) was conducted.
