data used for calculation of PNECs
h LC50 >100 mg/L
h EC50 >100 mg/L
h ErC50 = 14.7 mg a.i./L (95% c.l. 12.4 - 17.5 mg a.i./L)
h ErC10 = 4.42 mg a.i./L (95% c.l.3.70 - 5.18 mg a.i./L)
h NOEC = 1.3 mg a.i./L
in water: Readily
expected based on log Kow <3
aqua (freshwater), PNEC aqua (marine), PNEC aqua (intermittent release)
acute studies with freshwater fish, invertebrates and algae are
available for Undecylenamidopropyl
but no long-term or reproduction study, nor studies with marine
organisms. Therefore, in accordance with the Guidance on Information
requirements and chemical safety assessment, R.10, an assessment factor
of 1000 was applied and the PNEC aqua (freshwater) was derived from the
72 h ErC50 of 14.7 mg/L, determined with Desmodesmus
the most sensitive of the organisms tested. This results in a PNECaqua
(freshwater) of 14.7 µg/L.
assessment factor of 10000 was applied resulting in a PNECaqua (marine
water) of 1.47 µg/L.
assessment factor of 100 was applied resulting in a PNECaqua
(Intermittent release) of 147 µg/L.
A test on
ready biodegradation including a toxicity control conducted with the
source substance C8-10
available. In accordance with the Guidance on information requirements
and chemical safety assessment, Chapter R.10: Characterisation of dose
[concentration]-response for environment, 2008, an assessment factor of
10 was applied to the 14 d NOEC obtained in the Ready Biodegradability
test of 45 mg a.i./L resulting in a PNEC STP of 4.5 mg/L.
registration substance has a low vapour pressure of 1.52E-12 Pa at 25°C.
Due to the ionic structure and a corresponding low vapour pressure of
the substance a relevant concentration of the substance in the
atmospheric compartment is not expected. Based on this, no risk for air
breathing animals and humans is expected.
potential has been estimated to be low based on the log Kow of -1.38.
There is no concern for secondary poisoning and therefore no PNECoral
(secondary poisoning) was derived.
sediment(freshwater), PNEC sediment (marine waters), PNEC soil
toxicity tests with sediment dwelling or terrestrial organisms are
available. Thus, in accordance with the Guidance on information
requirements and chemical safety assessment, Chapter R.10:
Characterisation of dose [concentration]-response for environment, the
PNEC for freshwater and marine water sediment as well as the PNEC soil
have been calculated with the equilibrium partitioning method using
following data have been taken into account for calculation:
1.52E-12 Pa at 25°C (set to minimum value of 1E-06 in EUSES)
3100 mg/L at 20°C
-1.38 (set to minimum value of -1 in EUSES)
PNEC Aqua(marine water)
calculation resulted in a PNEC sediment(freshwater) of 0.0576 mg/kg
sediment dw, a PNEC sediment (marine waters) of 5.76E-03 mg/kg sediment
dw and a PNEC soil of 2.89E-03 mg/kg soil dw.
acute toxicity values >1 mg/L, no classification for aquatic acute
toxicity is required according to GHS Regulation EC No 1272/2008.
toxicity data are available only for algae. The substance is readily
biodegradable, and the log Kow is -1.38. Thus, according to GHS
Regulation EC No 1272/2008, no classification for aquatic chronic
toxicity is required.
