EC number: 269-052-1
CAS number: 68186-90-3
This substance is identified in the Colour Index by Colour Index Constitution Number, C.I. 77310.
The following acute toxicity tests with
aquatic organisms are available:
Leuciscus idus: LC50 (96 h) > 10000
mg/L; NOEC (96 h) = 10000 mg/L (BASF AG, 2000b)
Daphnia magna: EC50 (48 h) > 100
mg/L; EC0 (48 h) ≥ 100 mg/L (BASF AG, 2000c)
Scenedesmus subspicatus: ErC50 (72 h)
> 100 mg/L; ErC10 (72 h) > 100 mg/L; NOEC (72 h) ≥ 100 mg/L (BASF AG,
2000c) Pseudomonas putida: EC50 (30 min) > 10000 mg/L; EC10 (30
min) > 10000 mg/L (BASF AG, 1997).
All values were related to nominal
concentrations of suspensions (tests on fish and bacteria) or aqueous
extracts (test on daphnids and algae), no analytical monitoring was
performed. Previous analytical studies on aqueous extracts of a
suspension of this insoluble pigment demonstrated, that the expected
concentration of the substance in the extract is below the detection
limit of the analytical method. Tests on toxicity to fish indicate that
the test substance was suspended in water during the whole exposure
period (coloured and cloudy test solution).
However, based on short-term tests from each
of the four trophic levels, the substance can be regarded as acutely not
harmful to aquatic organisms.
This is in line with the results of a OECD
29 test: The transformation/dissolution concentrations of the most
relevant compounds Cr and Sb at a loading rate of 100 mg/L are far below
of the acute ERVs and are as well far below the chronic ERVs at a
loading rate of 1 mg/L
