In the key study, acute toxicity to Danio
was determined at 0.87 mg/L.
The acute toxicity of the test substance to Danio rerio exposed under
semi-static conditions for 96h was assessed according to the OECD 203
Guideline. Fish were exposed to a series of test solutions renewed every
day throughout the test period. Test item concentrations were determined
at each observation time on fresh and old solutions: as chemical
analysis of test samples taken on fresh and old solutions indicated that
measured concentrations of the test item did not remain within 80-120%
of the nominal concentrations and were not maintained over a 24h test
period (i.e. deviation >20%), the exposure concentrations were based on
the geometric mean of measured concentrations and determined as follows:
96h-NOEC 0.89 mg/L
96h-LOEC 1.71 mg/L
96h-LC10 0.75 mg/L
96h-LC50 0.87 mg/L
test records for fish toxicity are available. The first is reported as
the key study and is described above. The second study was not performed
according to GLP and is used as supplementary information.
substance was tested for acute fish toxicity in Leuciscus idus according
to DIN 38412/15. After 96 h exposure to nominal concentrations of 0.1,
0.215, 0.464, 1 and 2.15 mg/l an LC 50 was determined to be between 1 mg
/l (no mortality) and 2.15 mg/l (100% mortality). The NOEC was 1 mg/l.
no mortality occurred between 0.1 and 1 mg/l the geometric mean between
the highest concentration without effect and the lowest concentration
with 100% effect were considered to determine the LC50 to be 1.47 mg/l.
