Additional information

Gel-All MD was assessed for Acute toxicity (96 h LC50) to Rainbow Trout (Salmo gairdneri).

The test was conducted using semi-static test conditions according to OECD Guideline No. 203 and EEC Directive 67/548, Annex V C.1 as published in 84/449/EEC.

A single test concentration of 0.10 mg/l (in triplicate) was tested.

There were no mortalities or other adverse reactions to exposure in 30 fish exposed to a test concentration of 0.10 mg/L Gel-All MD for 96 hours

3, 6, 24, 48, 72 and 96 hr LC50: >0.10 mg/l

0.10 mg/L was the highest test concentration that could be prepared due to the limited solubility of the test material in water and having regards to the amount of auxiliary solvent permitted in the test.
