food.migration: food.migration

In HumanExposure/SHEDSDevel: The SHEDS-HT model for estimating human exposure to chemicals.

Description

Calculates chemical exposure from migration of chemicals from packaging or other contact materials into food (which is then consumed). This is added to the dietary output calculated by the food.residue function to establish a total exposure from the dietary pathway.

Usage

food.migration(cdata, sdata, cb, ftype)

Arguments

cdata	The list of scenario-specific information for the chemicals being evaluated. Generated internally.
sdata	The chemical-scenario data specific to relevant combinations of chemical and scenario. Generated internally.
cb	A copy of the base data set output from the make.cbase function, with columns added for exposure variables.
ftype	Food consumption database which stores data on consumption in grams per day of each food type for each person being modeled. Generated internally from the Diet_diaries data set.

Details

If migration data is stored in the cdata argument, this is added to the total exposure calculated in the food.residue function.

Value

dietary The calculated quantity of chemical exposure from food residue and migration of chemicals into food from packaging and other contact materials in grams per person per day.
