Additional information

This study was conducted to assess the toxicity of the test substance to Zebrafish (Danio rerio) in a 96 -hours static test. One concentration of 500 mg/L was used. The substance was dissolved in the test water. Maximum deviations from the theoretical value were + or - 2%. One replicate of 10 organisms was treated with the appropriate concentration of the test substance. A control group of 10 aorganisms was not exposed to tset substance. Dissolved oxygen, temperature and pH measuremnts were recorded at dosing and daily through termination. Observation of Mortality were made at 2-4, 24, 48, 72 and 96 hours after treatment. The test was terminated after 96 + and - 1 hours of exposure.

A 100% survival rate was observed in control fish, and a 100% survival rate was observed in fish treated with 500 mg/L of the test substance. Based on observation, the 96- hour median lethal concentration (LC50) of the test substance was determined to be > 500 mg/L

The NOEC was determined to be 500 mg/L.
