Description of key information
Acute Fish toxicity under static conditions.
Testing facility: Bayer Industry Services, Leverkusen
Study no. 2006/0035/04 performed on May 2, 2006.
The study was conducted in accordance with EEC Methods for Determination of Ecotoxicity Annex to Directive 92/69/EEC Part C, Method 1 Acute Toxicity for Fish which is in most parts equivalent to the OECD no. 203 "Fish, Acute Toxicity test".

Key value for chemical safety assessment
Additional information
Group of ten fish of the recommended size were exposed to a range of concentrations, nominly 25, 50 and 100 mg/l dissolved in water.
Auxiliaries used to prepare the test media were an ultrasonic bath, a magnetic stirrer and folded filters.
Observations were made on the numbers of dead fish and the incidence of sub-lethal effects after 2, 24, 48, 72 and 96 hours of exposure.
Results:
LC50 (24, 48, 72, 96h) > 100 mg/l
LC0 (96h) = 100 mg/l
All results are expressed in terms of nominal concentrations.
Water hardness = 11.6° dH (=207.1 mg/l CaCO3)
