The aim of this work was to review and synthesize the existing knowledge on ultrafine
particles in the air with a specific focus on those originating due to vehicles emissions. As …

Urban aerosol measurements are necessary to establish associations between air pollution
and human health outcomes and to evaluate the efficacy of air quality legislation and …

Nanotechnology is leading to the development in many field, of new materials and devices
in many fields that demonstrate nanostructure-dependent properties. However, concern has …

For over half a century, health-related aerosol exposure measurements have been
characterized in terms of the mass of material present per unit volume of air. Yet recent …

Ambient aerosol particles vary in size from a few nanometers to several micrometers. No
instrument is currently available to cover such a wide size range, and so a combination of …

The poor understanding of HONO sources in the daytime highlights the importance of the
heterogeneous photochemical reaction of NO2 with aerosol or soil surfaces. The conversion …

The aerodynamic particle sizer (APS) model 3321 (TSI, Inc., St. Paul, MN) aims to resolve
issues identified with an earlier APS, model 3320. These issues include discrepancies …

On the basis of the growing interest on the impact of airborne particles on human exposure
as well as the strong debate in Western countries on the emissions of waste incinerators …

Particle size is a key determinant of the hazard posed by airborne particles. Continuous
multivariate particle size data have been collected using aerosol particle size spectrometers …

Measurements are reported of particle number concentration at two urban sites within
Birmingham, UK. The measurements were made with a condensation particle counter (TSI …
