Additional information

Acute and chronic aquatic toxicity data for 2 of 3 trophic levels (marine & freshwater) are available for the read across substance THPS:

Algae: EC50 = 0.16 mg/L - 0.652 mg/l; NOEC = 0.063 mg/L

Invertebrate: LC50 = 0.6 mg/l - 19.4 mg/L; NOEC = 0.032 mg/L

The chronic toxicity to fish is scientifically unjustified for assessment because the acute toxicity to fish LC 50 = 72 mg/L-93 mg/l shows the most insensitive endpoint of all three trophic levels.
