Description of key information

The acute toxicity to algae (Selenastrum capricornutum, new name: Pseudokirchnerella subcapitata) of 1,3-dichlorobenzene was determined at an ErC50 (growth rate) of 9.2 mg/L  after 72 hours, and a NOEC (growth rate) of 3.2 mg/L was calculated.

Key value for chemical safety assessment

EC50 for freshwater algae:
9.2 mg/L
EC10 or NOEC for freshwater algae:
3.2 mg/L
