Aquatic acute toxicity
48 h, EC50 (Daphnia magna) = 0.045 mg/L (measured)
72 h, ErC50 ( Pseudokirchneriella subcapitata) = 0.640 mg/L
96 h, LC50 (Oncorhynchus mykiss) > 0.0241 mg/L (measured) = 0.045 mg/L
Aquatic chronic toxicity
72 h, ErC10 ( Pseudokirchneriella subcapitata) = 0.114 mg/L (measured)
not readily biodegradable
log Pow = 4.3 at 25 °C
Acute aquatic hazard: Category Acute 1, M-factor: 10. H400: Very
toxic to aquatic life
Long-term aquatic hazard: Category Chronic 10, M-factor: 1. H410:
Very toxic to aquatic life with long lasting effects
Acute aquatic hazard:
Most sensitive species Daphnia magna
Acute toxicity EC50 ≤ 1 mg/l. M-factor based on EC50 between 0.01 and
Long-term aquatic hazard:
The criteria for classification of a substance into the categories
Chronic 1 to 3 follow a tiered approach where the first step is to see
if adequate information on long-term toxicity is available allowing
long-term hazard classification.
In cases where the chronic data do not represent the species that is
considered the most sensitive in available short-term tests, the
classification and M-factor should be based on the data (acute or
chronic) that gives the most stringent outcome.
Therefore, acute toxicity data were taken into account for
classification instead chronic toxicity data (ErC10 value).
The test item is classified as aquatic chronic category 1 based on an
EC50 value of 0.045 mg/L (measured) of the most sensitive species
M-factor derived for acute aquatic hazard classification is also applied
to the long-term aquatic hazard classification.
