Factors governing pulmonary response to inhaled particulate matter.
Aerosol measurement: principles, techniques, and applications, third edition. Kulkarni P, Baron PA, Willeke K, eds. Hoboken, NJ: John Wiley and Sons, Inc, 2011 Jan; :793-803
The pulmonary response to an inhaled particle is influenced by its deposition fraction and the site of deposition. Pulmonary response would be minimized if the particle were rapidly cleared and be more pronounced if the particle had a high residence time in the lung. Once in the lung, the unique surface properties of a particle govern particle-cell interactions and affect the bioactivity and degree of pathogenicity of the particle. Nanoparticles are likely to exhibit greater adverse health effects than fine particles of the same composition due to their higher pulmonary deposition, their ability to enter the alveolar septa and perhaps the systemic circulation, and the role of particle surface area in affecting cellular toxicity.
