of dead fish and cumulative lethality [%] at various observation times
(Report, Table 6):
Cumulative lethality after 96 h was 0
% at the test loading rates of 5 and 10 mg/L. Cumulative lethality after
96 h was 71.4 % at the test loading rates of 25 and 50 mg/L and 100 % at
the test loading rate of 100 mg/L.
Results from dose-range finding
(Report, Table 3):
Short-term toxicity of 'Oligomerisation and alkylation reaction products
of 2-phenylpropene and phenol' (OAPP) to fish was examined in a valid
GLP guideline study (OECD TG 203). Due to intrinsic properties of the
test substance (UVCB substance), short-term fish toxicity was determined
based on loadings. The effective loading resulting in 50 % mortality
(EL50) was identified to be 25.8 mg/L test substance.
For OAPP as UVCB substance, solubility can be variable at different
substance concentrations. Therefore, effects observed are based on
loadings/loading rates (nominal values). The EL50 for short-term
toxicity to fish was determined to be 25.8 mg/L (effective loading).
