EC number: 939-478-9
CAS number: -
Under test conditions, the analogue URALAC ZW 3307 did not induce any visible effects on carp exposed to 0.40-0.46 mg/L (filtered solution) or 3.3 - 8.3 mg/L (unfiltered solution). The 96 h LC50 exceeds the water solubility limit of test substance and is considered to be >0.4 mg/L and the NOEC 0.4 mg/L, which corresponds to the measured concentration in the filtered solution. Since the registered substance and the substance URALAC ZW 3307 both contain the same main component and minor components with similar chemical structure, the 96 h LC50 for the registered substance exceeds the maximum soluble concentration of the test substance in test medium. See the full read-across report in section 13 for details.
In a 96 h
acute toxicity study, carp (Cyprinus carpio) were exposed under
static conditions to a single concentration of the analogue URALAC ZW
3307 at nominal concentrations of 0 (blank control) and 100 mg/L
(measured concentrations: 0.40 -0.46 mg/L for filtered solution; 3.3 -
8.3 mg/L for unfiltered solution).Owing to the low solubility of Uralac ZW 3307 P in water (<0.9 mg/l), concentration levels toxic for
carp could not be reached. The LC50 value is considered to be >0.4 mg/L
and the NOEC 0.4 mg/L, which corresponds to the measured
concentration in the filtered solution. The measured
concentrations in the non-filtered solution are not used
as this solution was turbid.The
present toxicity study is classified as reliable without restrictions
since it satisfies the requirements of the OECD Guideline No. 203.
the registered substance and the substance URALAC ZW 3307 both contain
the same main component and minor components with similar chemical
structure, the 96 h LC50 for the registered substance exceedthe maximum
soluble concentration of the test substance in test medium.
