Description of key information

The lowest calculated LC50 for fish of Quinine dihydrochloride is 395 g/L.

Key value for chemical safety assessment

LC50 for freshwater fish:
395 g/L
LC50 for marine water fish:
395 g/L

Additional information

The short-term toxicity to fish is calculated by ECOSAR v1.11. Lowest LC50 values for fish, 96 h, is 395 g/L derived by calculation from ECOSAR class Benzyl Alcohols. The calculated LC50 Neutral Organic Structure Analysis Relationship (baseline toxicity) for fish is 1250 g/L. The high values, which exceed the water solubility, reflect the low toxicity. The EPA recommends that empirical measures provide better results. However, empirical studies have not been done, so that we adapt the prediction.
