Additional information
PNEC intermittent release hazard assessment conclusion: PNEC aqua
(intermittent releases)
PNEC intermittent release assessment factor: 100.0
PNEC intermittent release extrapolation method: assessment factor
PNEC intermittent release justification: PNEC intermittent is based on
freshwater data available for three trophic levels. Reliable short-term
data are available for fish, algae and an invertebrate. The most
sensitive being a 48hr LC50 of >100.2 mg/L for Daphnia
Conclusion on classification
Not classified for toxicity based on substance is not readily biodgradable, one long-term algae result (NOEC = 500 mg/L) which is greater than 1 mg/L
