How do ultrafine particles affect the human body?
This is currently a hot topic in the research community. Apparently the mechanisms used by the human body to rid the lungs of contamination are very inefficient when the contamination is in the form of ultrafine particles. The subject is too complex to cover here. Please ask TSI for a copy of the article “Small particles – Big problem” written by Vicki Stone and Ken Donaldson of the Biological Sciences Department, Napier University, Edinburgh, Scotland.
