EC number: 201-645-2
CAS number: 85-98-3
The tests for three trophic levels were
performed (GLP guideline studies):
(48 h), invertebrates - 14.3 mg/L
(72 h), alga - 37.8 mg/L, NOECr (72 h) < 1.4 mg/L
(96 h), fish - 15.6 mg/L
centralite proved to be toxic to the freshwater organisms tested.
basis of the effective concentrations describing the respiration
inhibition of activated sludge caused by the test substance, Centralit,
the EC50 was found to be: EC50 > 1 000 mg.L-1
effect values for all three trophic levels are available. C&L is based
on data from short-term tests for fish, invertebrates and algae.
on study results Ethyl centralite is not ready biodegradable and
invertebrates Daphnia magna is the most sensitive species tested with
this compound – EC50(48 h) = 14.3 mg/L.
experimental results lead to classification Aquatic Chronic 3, H412.
ON CSA - PNEC DERIVATION
of acute study (48 -h test for daphnia magna) for Ethyl centralite are
used for derivation PNEC. Key value for CSA is EC50 = 14.3 mg/L
