The anterior adult human nasal passage contains hairs which act as a fibrous filter for inhaled particles. Particles which are collected by these hairs are likely removed by physical means and are unable to produce toxic effects in the respiratory tr

Indoor environmental pollutants can act as irritants, allergens, carcinogens, or infectious agents. This chapter focuses on human susceptibility to indoor environmental pollutants, here defined as inherent factors that alter exposure-response relatio

Nasal filter efficiency for particles has been described by several authors as showing large individual variations, probably somehow related to airflow resistance. Twelve children, aged 5.5-11.5 yrs and 8 aged 12-15 yrs were compared to a group of te

The calculation of fractional aerosol deposition in the human lung and methods for correction of breath-by-breath deposition data for inequalities in tidal volume are discussed. Three different methods are considered. Steady state and wash-in curves

The respiratory deposition patterns of hair spray aerosol inhaled via oral and nasal passages were measured in nine nonsmoking human subjects. For the first hour following inhalation, small airway resistance changes were determined using the flow rat

A new technique using a monodispersed aerosol of histamine delivered to sublobar bronchi through a flexible fiber-optic bronchoscope was used to study the role of the vagus nerve and the effect of anesthesia in the response of collateral channels to

We studied the effect of bronchial obstruction on central airway deposition of a 0.9% saline aerosol (MMAD = 1.12 micron; sigma g = 2.04) labeled with 99mTc sulfur colloid. Radioaerosol was inhaled on 2 occasions by 8 patients with asthma. The degree
