Description of key information

Mollusc acute study: 
EC50 value based on shell growth greater than 1000 mg/l.
LC50 value greater than 1000 mg/l.
Rotifer long-term study:
EC10 = 21 mg/l (reproduction)

Additional information

Two marine studies on two different taxonomic groups are available.

One short-term study valid with restrictions was found for molluscs. From this study (Ward and Boeri, 1991g) it can be seen that marine molluscs are not sensitive to sodium chlorate with an EC­50value based on shell growth and an LC50value both greater than 1000 mg/l.

One long-term study (valid without restrictions) is available for the rotifer Brachionus plicatilis. This study by Tobiesen (2010b) was performed according to standard guideline with GLP and chemical analysis of the test substance. B. Plicatilis turned out to be the most sensitive marine species with an EC10of 21 mg/l.
