Description of key information
Assessment of the effect of FAT 40870/ ATE on the growth of the green alga Pseudokirchneriella subcapitata.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 100 mg/L
- EC10 or NOEC for freshwater algae:
- 56
Additional information
The study was performed to assess the effect of the test item on the growth of the green alga Pseudokirchneriella subcapitata.
Following preliminary range-finding tests, Pseudokirchneriella subcapitata was exposed to an aqueous solution of the test item at concentrations of 10, 18, 32, 56 and 100 mg/Lfor 72 hours (the results are based on nominal concnetrations).
Exposure of Pseudokirchneriella subcapitata to the test item gave the following results:
