In this national guideline (DIN 38412,
part 15) study conducted to generally accepted scientific standards, the
48 hour LD50 of the test material (EC 231-272-0) was determined to be
160 mg/l (nominal). The test was conducted on Golden ide fish under
static conditions. The test result does not trigger classification and
labelling of the test material under the criteria of the EU
Classification, Labelling, & Packaging (CLP) regulation (1272/2008).
Test procedure in accordance with national standard methods with acceptable restrictions.
In a toxicity study on fish according to
the national standard test guideline DIN 38412 part 15 (Merck, 1989),
the toxicity of the test item was determined. Golden ide was used as
test organism and the LC50 (48 h) determined in the test was 160 mg/L.
Even though material without the final distillation step was used it can
be used as weight of evidence since the LC50 is above 100 mg/L and algae
and daphnids are the more sensitive species. Algae are the most
sensitive and, therefore, the result of the algae test will trigger the
the risk assessment has been conducted with a Risk Characterization
Ratio below 1. Hence, all relevant uses of the test substance are
considered to be safe. Therefore, and due to animal welfare reasons it
is not justified to conduct an additional fish test.
