Description of key information

The bioaccumulation potential of octadecanedioic acid, 1,18-dimethyl ester (ODDAME) is considered to be low.

Key value for chemical safety assessment

Additional information

The upper trophic bioaccumulation factor (BAF) of octadecanedioic acid, 1,18-dimethyl ester (ODDAME) was estimated by EPISuite v4.11, BCFBAF v3.01 to be low (10 L/kg). In addition, the predicted BAF for middle and lower trophic levels were 42 and 338 L/kg, respectively. The downwards trend in BAF from lower to higher trophic levels is indicative of biodilution, the opposite of biomagnification.
