OTHER TEST CONDITIONS
- Photoperiod: constant light
- Light intensity and quality: 60 - 120 (µE/s/m2)
- Salinity (for marine algae):
The ecotoxicity was determined by a marine phytoplankton test,
conducted according to ISO/DIS guideline 10253, using the algal
species Skeletonema costatum (ISO, 1999).
Concentration series of each chemical was prepared in triplicate
in a seawater-based algal culture medium, and the algal in
exponential growth phase was inoculated in each test solution at
algal concentrations of approximately 3 × 103 cells/ml. The choice
of test concentrations was based on a preliminary test with ten-fold
dilutions of the test substance (10–10,000 mg/l). As controls, algae
were also inoculated to algal culture medium without test substance.
All test tubes were incubated with agitation under constant
light intensity (60–120 E/s/m2) and a temperature of 20
±2 ◦C for 72 h. - Reference substance (positive control):
- not specified
Results and discussion
Effect concentrations
- Key result
- Duration:
- 72 h
- Dose descriptor:
- EC50
- Effect conc.:
- 20 mg/L
- Nominal / measured:
- nominal
- Conc. based on:
- test mat.
- Basis for effect:
- growth rate
- Remarks on result:
- other: (95% confidenbce interval 18-22 mg/L)
- Reported statistics and error estimates:
- From these parameters the effective concentrations
(mg/l) of test item inhibiting algal growth by 50% (EC50) relative
to the control cultures, were calculated with a 95% confidence
interval using the ecotoxicity calculation program TOXEDO (Water
Quality Institute, Hørsholm, Denmark).
Applicant's summary and conclusion
- Validity criteria fulfilled:
- not specified
- Conclusions:
- In a publication from Eide-Haugmo et al. 2012, a algae grwoth inhibition test with Skeletonema costatum according to ISO/DIS 10253 was performed. The EC50 for the test item was 20 mg/L.
