Description of key information

Based on the standard formula for ionic compounds having a log Kow lower than 5, a BCF of 3.162 is estimated (Currenta, 2009).

Key value for chemical safety assessment

Additional information

Measured bioconcentration factors (BCF) obtained in bioaccumulation studies for the mixture of dicarboxylic acids are not available.

However, a bioaccumulation potential for dicarboxylic acids is assessed from the octanol-water partition coefficient of the constituent adipic acid. Based on the standard formula for ionic compounds having a log Kow lower than 5, a BCF of 3.162 is estimated (Currenta, 2009). This value indicates that there is no potential for bioaccumulation of adipic acid in aquatic organisms.

As first, the logKow of the other constituents are also below 5, and second, the components have an ionic character the same formula will be applied to estimate a BCF for succinic and glutaric acid, resulting in the same value.
