EC number: 214-288-2
CAS number: 1119-86-4
The EC50-values with 95 % confidence intervals for inhibition of growth rate (ErC50) and yield (EyC50) after 72 hours were 41.3 (39.6 - 42.9) mg/L and 23.3 (19.4 - 27.0) mg/L, respectively. The EC10-values with 95% confidence interval for inhibition of growth rate and yield after 72 hours were 22.7 (20.5 - 25.1) and 13.8 (9.63 - 18.1) mg/L, respectively.
toxicity of the test item, decan-1,2 -diol, to the unicellular
freshwater green alga Pseudokirchneriella subcapitata was
determined according to OECD 201 and EC Method C.3.
study was conducted under static conditions. A stock solution of 100
mg/L was prepared with dilution water and treated with ultrasound. Six
concentrations were tested in a geometrical series with a dilution
factor of 2, to give nominal concentrations of 3.13, 6.25, 12.5, 25.0,
50.0 and 100 mg/L. Three replicates were tested for each test item
concentration and six replicates for the control. The concentrations of
the test item in all test concentrations and the control were
analytically verified by GC-FID at the start and the end of exposure.
The endpoints are based on the nominal test item concentrations.
EC50-values with 95 % confidence intervals for inhibition of growth rate
(ErC50) and yield (EyC50) after 72 hours were 41.3 (39.6 - 42.9) mg/L
and 23.3 (19.4 - 27.0) mg/L, respectively. The EC10-values with 95%
confidence interval for inhibition of growth rate and yield after 72
hours were 22.7 (20.5 - 25.1) and 13.8 (9.63 - 18.1) mg/L, respectively.
The NOEC-values for inhibition of both growth rate and yield after 72
hours were 12.5 mg/L.
