Problem
Using the simplified inhalation dose equation from class, consider the following scenario and calculate the air inhalation exposure dose for an infant less than 1 year old.
The average concentration of manganese in ambient air in the United States is 0.02 μg/m3, though concentrations near industrial sites can range from 0.22 to 0.30 μg/m3.[1] Calculate an inhalation dose for an infant living near an industrial site. Express your answer as mg/kg/day. State assumptions and the source for those assumptions.
Air concentration of agent (mg/m3) X volume of air inhaled per hour (m3/hr) X duration of exposure (hr)/day.
