Ultrafine particles in the atmosphere

Following the recognition that airborne particulate matter, even at quite modest concentrations, has an adverse effect on human health, there has been an intense research effort to understand the mechanisms and quantify the effects. One feature that has shone through is the important role of ultrafine particles as a contributor to the adverse effects of airborne particles. In this volume, many researchers in the field have collaborated to provide a state-of-the-art overview of the scientific and medical research on ultrafine particles.
