The implications of this difference for inhalation dosimetry and children’s risk assessment were evaluated in runs the U.S. Environmental Protection Agency (U.S. EPA) 1994 reference concentration (RfC) methodology ICRP model. Dosimetry estimates made 3-mo-old adults particles Category 1 2 reactive gases following respiratory-tract regions: extrathoracic (ET), tracheobronchial (BB), bronchioles (bb), (PU). Systemic nonreactive (Category 3) gases. Results suggest similar ET all types inhaled materials. BB was also across age groups except that ultrafine region twofold than In contrast, bb generally showed higher pa...
