Patologia cardio-vasculară indusă de expunere la pulberile din aer

Abstract

Atmospheric particles originate from a variety of sources and include combustion-generated particles, photo-chemically produced particles such as those from urban haze. Atmospheric particles contain inorganic ions, metallic compounds, elemental carbon, organic compounds, and crustal compounds. The organic fraction contains hundreds of compounds. Primary particles are emitted directly from sources whereas the secondary particles are formed from gases through chemical reaction. The modal classification is proposed for assess the particulate matters distribution. Cardio-vascular effects due to the exposure to particulate matters in air are represented by changes in the hearth rate, hearth rate variability, changes in the hearth conductivity, risk of acute hearth attacks or strokes due to alteration of coagulation pathway and occurrence of sudden death of cardiac causes.
