Additional information

In a 48-hour acute toxicity study, Copepod (Acartia tonsa) were exposed to Cardolite NC-603 (technical grade)at nominal concentrations of 0 and 1000 mg/L WAF under static conditions. 

 

No mortalities occured at a concentration of 1000 mg/l nominal WAF loading rate.

 

The 48-hour LL50 was >1000 mg/L nominal WAF.

 

The study is classified as Klimisch Code 2 (reliable with restriction) as it was performed to an internationally recognised method (ISO 14669).
