Definition Applied dose

The amount of a substance in contact with the primary absorption boundaries of an organism (e.g., skin, lung, gastrointestinal tract) and available for absorption. In exposure assessment, the amount of a substance in contact with the primary absorption boundaries of an organism (e.g., skin, lung tissue, gastrointestinal track) and available for absorption. The amount of a substance presented to an absorption barrier (i.e., skin, lung, or digestive tract) and available for absorption, but not yet having crossed the outer boundary of an organism. The amount of a substance in contact with the primary absorption boundaries of an organism (e.g., skin, lung, gastrointestinal tract) and available for absorption. Applied Amount of chemical in as above Dermal: (mg chem/kg soil) (kg soil directly touching skin) (% (e.g., of chem in soil actually skin, lungs, gastrointestinal touching skin) = mg chem. touching skin) = mg chem. actually touching skin. Respiratory: lung) = mg chemical actually (µg chem/m air) (m air mcg/m3 directly touching lung) (% of chemical actually touching lung absorption. Oral: (mg chem/kg food) (kg food consumed/day) (% of chemical touching g.i. tract) = mg chemical actually touching g.i. tract absorption (also absorbed dose rate: mg/day) chemical available to organ or cell (dose rate: mg chemical available to organ/day).
