Additional information
Conclusion on classification
The algae study is driving the classification for both acute (most sensitive endpoint) and chronic (only available NOEC) endpoints. Testing were done with river data (bulk approach) and a mitigation factor of 10 was used on river data to derive the correct classificaton of C16 -22 alkylamine.
Acute classification
The algae bulk approach ErC50 (river data) was 0.444 mg/L. This value was divided with a mitigation factor of 10 for classification purposes: 0.0444 mg/L.
Classification: Acute 1
M-factor: 10
Chronic classification
The substance is readily biodegradable
The substance has a BCF >500
The bulk approach NOEC (river data) was 0.159 mg/L. This value was divided with a mitigation factor of 10 for classification purposes: 0.0159 mg/L.
Classification: Chronic 1
M-factor: 10 (chronic data not available on all tropic levels and therefore acute M-factor is applied also on the long term hazard classification.
