No effects up to the limit of water solubility (EC50 > 0.13 mg/L and NOEC = 0.13 mg/L, mean measured, centrifuged test solution) for Daphnia magna (OECD 202)
One study is available on the short-term toxcity of
1,2-Benzenediol, 3,5-dialkyl-, 1,2-dicarboxylate to aquatic
invertebrates, and was used as key study. The test was conducted
according to OECD guideline 202 and GLP (Lehman, 2011). The test
organism Daphnia magna was exposed to the test substance in a static
system for 48 hours at nominal test concentrations of 0, 6.25, 12.5,
25.0, 50.0 and 100 mg/L (corresponding to mean measured test
concentrations of < 0.000507, 0.000923, 0.00379, 0.0163, 0.0394, and
0.130 mg/L). The test concentrations were prepared as water soluble
fractions (WSF), with separation of the undissolved test material
through centrifugation. 5% immobilisation was observed at the highest
test concentration. No further immobilisation occurred. The NOEC was
determined to be 0.13 mg/L (mean measured) and the EC50 > 0.13 mg/L
(mean measured), implying no effects up to the limit of water solubility.
