Additional information

For the test item Dust, steelmaking were derived:

PNEC(freshwater) = 0.1 mg/l

PNEC(marine water) = 0.01 mg/l

PNEC(aqua intermittent releases) = 1 mg/l

PNEC(STP) = 10 mg/l

All the toxicity for water organisms (fish, daphnia and algae) were found above 100 mg/l. No one from aquatic organisms seems to be more sensitive then others.

Conclusion on classification

There is not reason for classification.
