Results and discussion

Any other information on results incl. tables

It can be expected that the components of the substance are not bioavailable at all. Due to their hydrophobicity, it is very likely that components will adsorb to sediment and particulate matter. Furthermore, steric hindrance at passage of gill membranes or cell membranes of respiratory organs can be very important for substances that have a molecular weight higher than 500 or a molecular size larger than 9.5 A. According to the EU Technical Guidance Documents, substances with a molecular weight higher than 700 are unlikely to bioaccumulate significantly (regardless of the log Pow value.
