EC number: 242-362-4
CAS number: 18479-58-8
The acute toxicity of dihydromyrcenol to Daphnia magna was
studied under static conditions. Daphnids were exposed to test
chemical at nominal concentrations of 0, 10, 18, 32, 56 and 100 mg/l
(confirmed by analysis to have represent achieved concentrations) for
48 hours. Mortality/immobilization or other adverse effects were
observed daily. The 48–hour EC50was 38 mg/l.
The 48–hr NOEC based on immobilization was 10 mg/l.
Test Organism Age: 1st instar (<24 hours old)
Test Type: Static
48h EC50: 38 mg/l
48h NOEL: 10 mg/l
Reliable experimental data with the test item are available to assess acute toxicity to daphnia magna.
A 48h EC50 value of 38 mg/l was obtained from the key study of the
test item toxicity to aquatic invertebrates.This value correlates well
with the acute toxicity to Daphnia magna study using the read-across
analogue substance linalool which reports a 48h EC50 value of 59 mg/l
(Linalool, OECD SIDS report, 2002).
