Additional information

In an Acute Immobilisation Test on Daphnia according to OECD 202 an EC50 of 157.2 µg/L was assumed. The NOEC is 94.3 µg substance per liter time weighted mean (TWM). The test was conducted under static conditions. Effects on immobilization were determined after 24 and 48 hours at nominal concentrations of 125, 250, 500, 1000 and 2000 µg/L Immobilization was significantly increased starting at a time weighted mean (TWM) concentration of 164.4 µg substance per liter.

This study is classified as reliable without restriction and satisfies the guideline requirements for an acute toxicity study with invertebrates.
