Description of key information

- EC50 (96h) > 10 mg/L for freshwater algae [guideline equivalent or similar to EPA OPP 72-2 (Aquatic Invertebrate Acute Toxicity Test)] 
- EC50 (96h) > 11.48 mg/L for marine water algae [test followed internal procedures of the laboratory (Static acute Mysid shrimps toxicity test, June 1982)]

Key value for chemical safety assessment

EC10 or NOEC for freshwater algae:
10 mg/L
EC10 or NOEC for marine water algae:
11.48 mg/L

Additional information

This endpoint is filled from data from one study in Selenastrum capricornutum (freshwater algae) (Maziarz, 1983a) and another in Skeletonema costatum (saltwater algae) (Maziarz,1983b). The no observable effect concentration (NOEC) for 'diallyl 2,2'-oxydiethyl dicarbonate' in Selenastrum capricornutum is 10 mg/L and in Skeletonema costatum 10µL/L (=11.48 mg/L).
