CAS number: -
96 h LC50 in Pseudokirchneriella subcapitata > 100 mg ai/L with the NOEC at 100 mg ai/L.
The acute toxicity of the test material to Pseudokirchneriella
subcapitata was investigated in accordance with the standardised
guidelines OECD 201, EU Method C.3, EPA OTS 797.1050 and EPA OPPTS
850.5400 under GLP conditions. The study was awarded a reliability score
of 1 in accordance with the criteria for assessing data quality set
forth by Klimisch et al. (1997).
Algae were exposed to the test material for 96 hours at a limit
concentration of 100 mg a.i./L under static conditions. There were no
abnormalities detected in any of the control and test cultures and no
effects on either the growth rate or biomass.
Under the conditions of this study, the 96 h EC50 was greater than 100
mg ai/L. Correspondingly the No Observed Effect Concentration (NOEC) was
100 mg ai/L.
