Description of key information

MCPP-P 2-EHE hydrolyses rapidly in natural water. Therefore, the hydrolysis product MCPP-P acid was used for further assessment of MCPP-P 2-EHE with respect to its potential for bioaccumulation.

The bioaccumulation of the hydlosis product, MCPP-P acid, in fish species: Lepomis macrochirus, was experimentally determined to be BCF (edible fraction) = 1.2, BCF (non-edible fraction) = 5.5 and BCF (whole fish) = 3.0, respectively. Thus, MCPP-P 2-EHE has low potential for bioaccumulation as its hydrolysis products in higher organims.
