A 96-hour acute toxicity study with common carp (Cyprinus carpio) was
conducted in accordance with the OECD test guideline 203 and in
compliance with GLP.
A limit test was performed with a single test concentration of 100%
saturated solution of a nominal 100 mg/L solution, under static
conditions. The mean measured test concentration was determined to be
Under the conditions of the test, the 96-hour LC50 (mortality) was
determined to be >1.3 mg/L, based on mean measured concentrations.
Due to the very low solubility of
4,4’-(1-phenylethane-1,1-diyl)bis(heptyloxybenzene) in the test medium,
concentration levels that may be toxic for fish could not be reached.
The laboratory study report stated that the test item was not completely
soluble in the test medium at the loading rate initially prepared.
This acute toxicity study is considered acceptable and satisfies the
guideline requirement for short-term toxicity to fish.
In a reliable (Klimisch 1) 96-hour acute toxicity study, common carp (Cyprinus
carpio) were exposed to a single test concentration (limit test)
under static conditions in accordance with the OECD test guideline 203
and in compliance with GLP.
Under the conditions of the test, the LC50 (mortality) was determined to
be >1.3 mg/L, based on mean measured concentrations.
The EC50 value is greater than the limit of solubility of the test
The test validity criteria were met and there were no significant
deviations noted to affect the integrity of the study. This
acute toxicity study is considered acceptable and satisfies the
guideline requirements for a short-term toxicity study to fish.
