- Dermal absorption:
Roper, C. S. (2005). The in vitro percutaneous absorption of radiolabelled Hexabromocyclododecane (HBCD) through human skin. Testing laboratory: Inveresk, Tranent, EH33 2NE, Scotland, UK. Report no.: 25031. Owner company: American Chemistry Council, Brominated Flame Retardant Industry Panel, Arlington, VA 22209, USA. Report date: 2005-04-26.
Due to the variety and reliability of information available, a weight of evidence approach was used for this endpoint.

Key value for chemical safety assessment

Additional information

A weight of evidence approach was considered to be appropriate to the Toxicokinetic endpoint due to the reliability and variety of information available. Although most of the investigations presented here were conducted on the registered substance, Scholtz et al, 2002, was conducted on a similar substance, and so the standard read-across protocols were used for this investigation.
