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 and the fast biodegradability in soil, the bioaccumulation in terrestrial species does not need to be investigated.
