Description of key information

Acute studies are available for fish, Daphnia magna, and algae. Further to this a chronic daphnia reproduction testand chronic fish study is available.


 


Acute aquatic toxicity studies


The 96 -hour acute LC50 for fish was determined to be 2.32 mg/L in an EU method C.1 test.


In an OECD 202 guideline test the EC50 for Daphnia magna was found to be 3.09 mg/L and the NOEC was determined to be 1.73 mg/L.


In an OECD 201 test the 72-hour EC50 for the algae Selenestrum capricornutum (new name Pseudokirchneriella subcapitata) determined to be 0.475 mg/L and the NOEC 0.247 mg/L based on growth rate.


 


The 3 -hour EC50 for aquatic microorganisms was found to be >10000 mg/L.


 


Chronic aquatic toxicity studies


The 21 -day NOEC for reproduction in Daphnia magna was found to be 0.258 mg/L and the LOEC was found to be 0.455 mg/L in an EU method C.20 test.


 


An OECD 210 study on Danio rerio found an EC10 of 0.0322 mg/L (measured concentration based on test material).

Additional information

Following ECHA decision on a compliance check (decision number: CCH-D-2114495479-27-01/F) a study according to OECD Guideline for Testing of Chemicals, No. 210 "Fish, Early-life Stage Toxicity Test". Adopted on July 26, 2013 with Danio rerio was conducted and is included in section 6.1.2. The aim of the study was to determine lethal and sub-lethal effects of the test item on the early-life stages of Danio rerio (zebrafish).
