Nowadays, one of the most important topics in context of environmental and health hazard research became airborne particles. Exposure to traffic-related PM plays an important role in the development of adverse health effects. Traffic-generated particles are associated with cardiovascular and pulmonary effects, as shown by both epidemiological and toxicological studies [1-8]. Some of these studies suggest that brake wear particles might contribute to these adverse effects [5,6]. Specific health concerns are related to the allergenity of tyre components such as Polycyclic Aromatic Hydrocarbons (PAH’s) and latex, and the heavy metals used in brake linings. All of these compounds have toxic, mutagen attributes [9], but above all are respiratory sensitizers, inducing irreversible allergic reactions in the respiratory system.
