Fraction of chemical gas phase in air

Hi,

 

May I know what relation exists between the fraction of chemical gas phase in air and the bioaccumulaiton factor in root? 

Why the mentioned fraction is not 0 only when the bioaccumulation factor is not 0?

Thanks.

 

Regards,

Andrea.

Corrective update for gas phase fraction in air

Thank you for this comment. The equation contains a wrong link: it should check if a chemical is inorganic or organic and not if a bioconcentration factor in root is available. The following corrective update has been applied that does not influence the current characterization factors as typically the bioconcentration factor in root is not available:

USEtox 2.0 main file, sheet fate: change in eq. of K115 reference from 'Substance data'!AI5 to 'Substance data'!AO5

This and other minor corrective updates will be incorporated into USEtox 2.0 and made publically available in a minor update version.
