Description of key information

Short-term toxicity to aquatic invertebrates


In a limit test according to OECD TG 202 with Daphnia magna the 48-hour EC50 of the read across source substance hexane-1,2-diol (CAS 3710-31-4) was determined to be > 110 mg/L (nominal). Based on this result the 48-hour EC50 of the target substance heptane-1,2-diol is considered to be > 110 mg/L.


 


Toxicity to aquatic algae


In an Algae Growth Inhibition Test according to OECD TG 201 with Pseudokirchneriella subcapitata, the 72-hour EC50 and EC10 for the read across source substance octane-1,2-diole (CAS 1117-86-8) was higher than 100 mg/L (nominal) based on the growth rate. By applying a read across approach the 72-hour EC50 and EC10 (growth rate) of the target substance heptane-1,2-diol is considered to be > 100 mg/L.
