Why are ultrafine particles important with regard to Indoor Air Quality (IAQ)?
Recent case studies using an ultrafine particle counter like the P-TRAK® ultrafine particle counter show that the elimination of ultrafine particle sources in indoor environments causes IAQ complaints to cease. Aerosol research scientists and epidemiologists suspect a causal link exists between ultrafine particles and health effects. For example, research has shown that high concentrations of inert ultrafine particles can cause hemorrhagic bleeding in the lungs of rats. A copy of the article is available on the TSI website “Ultrafine Particles: A New IAQ Metric” written by Peter A. Nelson of TSI Incorporated and printed in the August 1999 issue of INvironment Professional.
