Additional information
Two study summaries have been submitted. The study summary short-term toxicity to fish.001 states a precise LC50 value of 22.50 mg/l, whereas the summary short-term toxicity to fish.002 states a range from 22 to 46 mg/l. The value of 22.0 is taken as the LC50 endpoint, as this is the worst scenario suggested by the results found.
The summary short-term toxicity to fish.002 also states a NOEC value of 4.84 mg/l, and this result is accepted to be the NOEC value.
