Additional information
Ecotoxicity studies with AAPBs did not show acute toxicity values < 1 mg/L.
Short-term toxicity to aquatic organisms
Fish: LC50(96 h) = 1.1 mg/L
Invertebrate: EC50(48 h) = 1.9 mg/L
Algae or aquatic plants: ErC50= 2.4 mg/L
Long-term toxicity to aquatic organisms
Fish: 37 d/100 d NOEC=0.135 mg/L
Invertebrate: 21 d NOEC=0.3 mg/L
Algae or aquatic plants: 72 h NOEC=0.6 mg/L
Biodegradation in water: Readily biodegradable
Bioaccumulation: BCF < 71
logKow: 4.2137 (calculated, weighted mean)
Ozone layer: Based on the very low vapour pressures of the ionic substances, the atmosphere is not the target compartment of environmental distribution. The registration substance is not expected to reach the atmospheric stratosphere in appreciable amounts where it is rapidly degraded by reaction with OH radicals and therefore is not expected to present a danger to the structure and/or the functioning of the stratospheric ozone layer.
The registration substance does not need to be classified with regard to environmental effects.
The substance is readily biodegradable. The ready biodegradability of the substance was proven in a number of tests conducted under different conditions (aerobic, anaerobic, marine conditions). Toxicity towards aquatic micro-organisms is expected to be of no concern for sewage treatment plants. Long-term exposure of aquatic organisms is therefore unlikely.
Bioaccumulation in organisms is considered to be low. Therefore, secondary poisoning through the food chain is of no concern for the registration substance.
The exposure and uptake of the substance by soil dwelling organisms is unlikely as the target compartment of discharge and environmental distribution is the hydrosphere and the substance is readily biodegradable. Sediment dwelling organisms may be exposed to the test substance, but it can be assumed that the test substance especially the long-chain members are adsorbed onto sediment organic matter and therefore bioavailability will be reduced. Furthermore, based on the available data, bioaccumulation is expected to be low and the test substance proved to be (readily) biodegradable under different conditions (marine water, aerobic, anaerobic).
Conclusion on classification
In conclusion, ecotoxicity studies with AAPBs did not show acute toxicity values < 1 mg/L and the AAPBs proved to be readily biodegradable.
According to Directive 67/548/EEC, AAPBs need not to be classified as 'dangerous to the aquatic environment' and therefore labelling is not necessary.
According to GHS Regulation EC No 1272/2008, AAPs does not need to be classified as 'hazardous to the aquatic environment' and needs not to be classified as 'hazardous to the ozone layer'. Therefore labelling is not necessary.
