The toxicity to aquatic invertebrates was assessed in a test with Daphnia magna according to OECD 202 (2010):EC50 (48h) > 100 mg/LNOEC (48h) ≥ 100 mg/LLOEC (48h) > 100 mg/L
The acute toxicity to aquatic invertebrates
of triethyl citrate was tested according to OECD Guideline 202 and EU
Method C.2 in a static 48-hour immobilisation test with Daphnia magna
STRAUS as test organisms (2010). The study was conducted under
certificated GLP compliance. The only concentration tested was nominal
100 mg test item/L. Additionally a control was tested in parallel (test
water without addition of the test item). Thus a limit test was
performed in accordance with OECD Guideline 202 to demonstrate that the
test item has no toxic effect on the test animals up to this
concentration. The immobility of the Daphnia (20 Daphnia
per control and test concentration) was determined by visual observation
after 24 and 48 hours, those animals not able to swim within 15 seconds
after gentle agitation of the test beaker were considered to be immobile
(even if they could still move their antennae). After 48 hours of
exposure no immobilisation of the test animals was observed in the
control and in the only test concentration of nominal 100 mg/L. The
48-hour NOEC was determined to be ≥ 100 mg test item/L. The 48-hour LOEC
was determined to be > 100 mg test item/L The 48-hour EC50 value was
determined to be > 100 mg test item/L.
