This study was performed to assess the chronic toxicity of FAT 40863/A TE to the freshwater invertebrate Daphnia magna.
This study was performed to assess the chronic toxicity of
the test item to the freshwater invertebrateDaphnia magna. The
method followed was designed to be compatible with the OECD
Guidelines for Testing of Chemicals (2012) No 211, "Daphnia
magnaReproduction Test" referenced as Method C.20 of
Commission Regulation (EC) No. 440/2008 and the US EPA Draft
Ecological Effects Test Guidelines OCSPP 850.1300 "Daphnid
Chronic Toxicity Test". The test was conducted following a
semi-static design with test solutions renewed three times per
Based on the results of an acute toxicity test (Harlan
Study Number: 41304704),Daphnia magnawere exposed (10
replicates of a single daphnid per group) to an aqueous solution
of the test item over a range of nominal test concentrations
of 1.0, 3.2, 10, 32 and 100 mg/L for a period of 21 days. The
test solutions were renewed 3 times per week.
The numbers of live and dead adult Daphnia and young
daphnids (live and dead) were determined daily. The Daphnia were
fed daily with a mixture of algal suspension and Tetramin®flake
Analysis of the freshly prepared 100 mg/L test
preparations on Days 0, 5, 12 and 19 and of the old or expired
test preparations on Days 3, 7, 14 and 21 showed measured test
concentrations to range from 102% to 106% of nominal value and
so the results are based on nominal test concentrations only.
Exposure ofDaphnia magnato the test item gave the
following results based on the nominal test concentrations:
No Observed Effect Concentration (NOEC)
Lowest Observed Effect Concentration (LOEC)
Maximum Acceptable Toxicant Concentration (MATC)*1
⃰Result calculated from total neonates produced
calculated from lowest calculated NOEC and LOEC
