Description of key information

In a reliable study according to OECD 305, BCF values were calculated based on the limit of the detection of HPLC; for 0.1 mg/L test concentration a BCF of 0.3 and for 1 mg/L a BCF of 3 were calculated, respectively.

In a supporting study, a calculated BCD of 3.2 was derives by EpiSuite (BCFWIN v 2.15).

In conclusion, OBSH has very low potential to bioaccumulat in aquatic organisms.
