Description of key information

Both the EC50 for growth rate reduction (72 h-ERC50) and the EC50 for yield inhibition (72 h-EYC50) exceeded 0.2 mg/l, being the Time Weight Average concentration in a WAF prepared at a loading rate of 100 mg/l.

Key value for chemical safety assessment

EC50 for freshwater algae:
100 mg/L

Additional information

Algal growth inhibition test was performed according to OECD guideline No. 201 under GLP compliance. The result showed no reduction of growth rate or inhibition of yield was recorded at any of the WAFs of Alkylated Naphthalene tested. Both the EC50 for growth rate reduction (72 h-ERC50) and the EC50 for yield inhibition (72 h-EYC50) exceeded 0.2 mg/l, being the Time Weight Average concentration in a WAF prepared at a loading rate of 100 mg/l.
