Additional information

Based on the low octanol water partition coefficient (log Kow 0.59) a low bioaccumulation of hydroquinone is expected. A bioaccumulation factor BCF of 3.162 L/kg is calculated from EPISUITE 4.00 (BCFBAF v3.00). The low potential for bioaccumulation is confirmed by the study using of 14C-labelled Hydroquinone and the fresh water fish Leuciscus idus melanotus. After 3 days, a BCF of 40 L/kg was determined. Radioactivity determination of the BCF includes possibly formed metabolites.

Due to low bioaccumulation potential, the fast biodegradability and the low adsorptive potential (Koc 9 L/kg), the bioaccumulation of hydroquinone in sediment species does not need to be investigated.
