according to
Guideline:
OECD Guideline 202 (Daphnia sp. Acute Immobilisation Test)
Deviations:
no

yes (incl. certificate)
Analytical monitoring:
yes
Remarks:
It will be difficult due to the very low water soulbilty

140 and 250 mg/L as CaCO3
Test temperature:
20 ± 2 °C
pH:
6.0 to 9.0
Dissolved oxygen:

Duration:
48 h
Dose descriptor:
LC50
Effect conc.:
ca. 0 mg/L
Nominal / measured:
nominal
Conc. based on:
test mat.
Basis for effect:
other: limit of water solubility
Validity criteria fulfilled:
yes
Conclusions:
LD50 is < 0.00013 mg/L due to the limit of solubility, no effects observed.
Executive summary:

No effects observed at the limit of solubility

Description of key information

LD50 is < 0.00013 mg/L due to the limit of solubility, no effects observed. True value is below the value reported due to this being the limit of detection.

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
0 mg/L
