Additional information

Aquatic compartment PNECs are derived from LC50 value for fish (LC50 is 10 - 18 mg/L) which is the lowest short-term result from representatives of three taxonomic groups (fish, crustaceans, algae).

PNEC sed and PNEC soil were calculated from equilibrium partitioning. The followed equation for freshwater and marine compartment was used:(0.783 +0.0217xKoc)xPNEC water and for calculation of the PNEC soil:(0.174 +0.0104xKoc)xPNEC water.

The PNEC STP was calculated using NOEC value and assessment factor 10 was used for PNEC derivation.

Furthermore taking into account the solubility of the substance is not expected to distribute in sediments and/or soils but in aquatic compartment.

Conclusion on classification

Isobornyl acetate is not classified for environmental toxicity.
