The toxicity of the substance to fish
(Zebrafish) was assessed in a static acute toxicity test according to
the EU Method C.1. 10 fish per concentration and water control were
used. Fish were exposed to the following concentration, over a period of
96 hours: 56, 100, 178, 316 and 562 ppm. Water samples were taken from
the bath at the beginning and at the end of the experiment; the tested
concentrations resulted to be mainteined at least 80 per cent of the
nominal one, over the test period.
No abnormal responses of the fish were
observed. The LC0 at 96 hours resulted to be 100 ppm, while the LC100
resulted to be 178 ppm.
The LC50-values were calculated with the
geometric mean, Spearman-Kärber- and the Probit-Method; furthermore, the
value has also been graphically determinated. The LC50 at 96 hours
resulted to be 117.7 ppm and 116 ppm, based on geometrical mean and
graphically determinated, respectively.
LC50 (96h): 117.7 mg/l (meas. geom. mean)
LC50 (96h): 116 mg/l (graphically
Not harmful/toxic for short-term exposure
The toxicity of the substance to fish was
assessed in a static acute toxicity test using Zebrafish, according to
the EU Method C.1. 10 fish per concentration were used. Fish were
exposed to the following concentration, over a period of 96 hours: 56,
100, 178, 316 and 562 ppm. Water samples were taken from the bath at the
beginning and at the end of the experiment and the tested concentrations
resulted to be maintained at least 80 % of the nominal one, over the
test period. No abnormal responses of the fish were observed. The LC0 at
96 hours resulted to be 100 ppm, while the LC100 resulted to be 178 ppm.
The LC50 at 96 hours resulted to be 117.7 ppm and 116 ppm, based on
geometrical mean and graphically determined, respectively.
A second test is available. The experiment
was performed using five Zebrafish per test concentration, under
semi-static conditions. Fish were exposed to three concentrations, i.e.
46, 64 and 100 mg/l. One death occurred at the concentration of 64 mg/l
after 24 hours; at the highest concentration of 100 mg/l 3 fish died
after 24 hours and the remaining fish died after 48 hours. The LC50 was
determined to be 86.4 mg/l of active ingredient.
