The dose for each pathway is the sum of contributions to the animal's diet. In particular,
there is fresh feed, stored hay, stored grain, soil, and drinking water. Each of these has a
common factor made of the annual amount consumed by the individual, the ingestion dose
factor, the equilibrium transfer factor, the water concentration, and the ingestion period.
