Above-ground plants parts concentration due to transfer from soil to above ground plant tissues

Dear USEtox Team,

I'm studying USEtox and in my research group they asked me to study in deepth the equations 134-135 136 in the Documentation about:

- above-ground plant-parts concentration due to transfer from soil to above ground plant tissues (134)

- above-ground plant-parts concentration due to transfer from particulate matter in air to above ground plant tissues (135)

-above-ground plant-parts concentration due to transfer from air gas phase to above ground plant tissues (136)

Is there any book/article that can support me in the study of these equations?

I have difficult to understand these equations.

Weighted intake of meat cattle from soil what is referring to? Does it refer to the amount of contaminants that the grass has taken from the roots and therefore from the soil (grass that animal eats )? Is this interpretation correct?

Thanks a lot for your availability.

Uptake into plants

A detailed description about the plant uptake pathways in USEtox is provided in the Supporting Information, Section S.1 of Rosenbaum et al. (2011).

Intake of meat cattle from soil refers to ingestion of soil by the cattle. Intake of grass and other animal feed is considered in intake of meat cattle from vegetation.
