Additional information

Disperse Red 302:1 was evaluated for toxicity to fish, Daphnia, Lemna and bacterial organisms.

The key values for Disperse Red 302:1 regarding aquatic toxicity were:

48-hour LC50 to fish: >1000 mg/L

48-hour EC50 to Daphnia: >100 mg/L

7-day EyC50 and ErC50 to Lemna : >100

7-day 7-day NOErC & NOEyC and the LOErC & LOEyC: >100

3 hour IC50 to bacterial organisms: >100 mg/l

The test substance is considered to be inherently biodegradable. The biodegradation of the test substance after 28 days is 21 % and the BOD5 after 5 days is 0 mg O2/g.

Conclusion on classification

Based on the absence of acute aquatic toxicity on three trophic levels tested, the substance is neither classifiable for acute or chronic aquatic toxicity according to CLP (Regulation EC No 1272/2008) or DSD (Directive 67/548/EEC).
