Road traffic is one of the main sources of particulate matter in the atmosphere. Despite its
importance, there are significant challenges in quantitative evaluation of its contribution to …

Airborne particulate matter poses a serious threat to human health. Exposure to nanosized
(< 0.1 μm), vehicle-derived particulates may be hazardous due to their bioreactivity, their …

Concentrations of particulate matter less than 1 μm, 2.5 μm, 10 μm and their contents of
heavy metals were investigated in two different stations, urban and roadside at Algiers …

Delhi, the capital of India, suffers from heavy local emissions as well as regional transport of
air pollutants, resulting in severe aerosol loadings. To determine the sources of these …

Introduction Nanotechnologies are among the fastest growing areas of scientific research
and have important applications in a wide variety of fields. The data suggest that in the future …

Abstract Knowledge of the human health impacts associated with airborne nanoparticle
exposure has led to considerable research activity aimed at better characterising these …

To characterize the redox activity profiles of atmospheric aerosols from primary (traffic) and
secondary photochemical sources, ambient quasi-ultrafine particles were collected near …

The recent economic crisis in Greece resulted in a serious wintertime air pollution episode in
Thessaloniki. This air quality deterioration was mostly due to the increased price of fuel oil …

Road dust has been identified as one of the main sources of outdoor PM 10 in Bogota (a
Latin American megacity), but there are no studies that have analyzed the physicochemical …

In this study, two different types of assays were used to quantitatively measure the redox
activity of PM and to examine its intrinsic toxicity: 1) in vitro exposure to rat alveolar …
