Toxicity to aquatic algae and cyanobacteria
Administrative data
Link to relevant study record(s)
Description of key information
By applying weight of evidence approach the endpoint values was found to be EC50=162mg/l;NOEC=3.211644mg/l and LOEC=21.7231 mg/l in a 72 to 120 hrs.study on the basis of growth and population effect.Thus,considering the CLP Criteria for aquatic classification of the substance , it is concluded that Phenetole does not exhibit toxicity to aquatic algae and cyanobacteria(Pseudokirchnerella subcapitata).
Key value for chemical safety assessment
- EC10 or NOEC for freshwater algae:
- 3.212 mg/L
Additional information
Based on studies reviewed for toxicity to aquatic algae and cyanobacteria from reliable sources having Klimish rating 2and 4 for target and readacross.
