Description of key information

The effect of the test item on the growth of Pseudokirchneriella subcapitata has been investigated and gave EL50  values of greater than 100 mg/L loading rate WAF.   

Key value for chemical safety assessment

Additional information

The acute toxicity (inhibition of growth) of the test item on algae for a duration of 72 hours was assessed according to the OECD testing guideline 202.

Algae (Pseudokirchneriella subcapitata) were exposed to a single loading rate: 100 mg/L. Due to the low aqueous solubility and complex nature of the test item, WAF solution was prepared.

The toxic effect measured during the assay was the growth inhibition after 72 hours of exposure to the test item.

The loading rates causing 50% and 10% effect (EL50 and EL10) were higher than 100 mg/L.
