CAS number: 104-57-4
In a 72 h static toxicity test with
freshwater green algae Pseudokirchneriella subcapitata an ErC50 and
ErC10 based on the growth rate of 206 mg/L (144 - 302) and 44.5 mg/L (9.73
- 92 .4) were determined, respectively. The NOEC-value for inhibition of
growth rate was 4.26 mg/L. The results are based on the time weighted
average test item concentration.
In a static toxicity test with freshwater
green algae Pseudokirchneriella subcapitata, the effects of the test
item were determined according to OECD 201 (2011). The test was
conducted over a period of 72 h with the nominal concentrations of 10.3,
25.6, 64.0, 160 and 400 mg/L, corresponding to the time weighted average
test item concentrations of 4.25, 7.01, 53.6, 140 and 390 mg/L. Under
the conditions of this test, the test substance was found to inhibit the
growth of the green alga after 72 hours with an ErC50 of 206 mg/L (144 -
302) and an ErC10 of 44.5 mg/L (9.73 - 92.4), respectively (based on
time weighted average test item concentration). The NOEC-value for
inhibition of growth rate was 4.26 mg/L.
