Additional information

The acute toxicities of 3 representative aquatic species are tested, therefore PNEC in freshwater compartment and marine compartment can be derived by assessment factors. PNECs in marine compartment, sediment of fresh water and sediment of marine water will be extrapolated by PNEC in freshwater compartment.

The PNEC soil is based on the result for the long-term toxicity test of BDP to the terrestrial plant.

Conclusion on classification

The acute toxicity of BDP to the most sensitive species fish (Rainbow Trout )acute toxicity study EC50(96hr): >0.17 mg/l. >0.17 mg/l is equivalent to => 100 mg/l due to the low water solubility of the test substance BDP. So no acute toxicity is recorded at levels up to the water solubility. The substance is not rapidly degradable and have an experimentally determined BCF of 120. According to the criteria in Regulation 1272/2008, BDP is no classfied as hazardous to environment.
