    C = Concentration of the chemical in the contaminated environmental medium (soil or water) to which the person is exposed. The units are mg/kg for soil and mg/L for water. IR i = Intake rate of the contaminated environmental medium for age bin "i". The units are kg/day for soil and L/day for water. BW i = Body weight of the exposed person for ...
