Pedestrians in Traffic Environments: Ultrafine Particle Respiratory Doses
Particulate matter has recently received more attention than other pollutants. PM10 and PM2.5 have been primarily monitored, whereas scientists are focusing their studies on finer granulometric sizes due both to their high number concentration and their high penetration efficiency into the respiratory system. The purpose of this study is to investigate the population exposure to UltraFine Parti...
متن کامل[Human health effects of ultrafine particles].
Epidemiologic and clinical studies have linked elevated concentrations of ambient ultrafine particles (UFPs) to adverse health effects. In particular, has been demonstrated an association between UFPs exposure and occurrence of acute respiratory infections, lung cancer, chronic chronic obstructive pulmonary diseases and cardiovascular diseases. Although the biological mechanisms behind these as...
متن کاملUltrafine Particle References
A review of the physical characteristics of sulfur-containing aerosols, with respect to size distribution of the physical distribution, sulfur distributions, distribution modal characteristics, nuclei formation rates, aerosol growth characteristics, and in situ measurement, has been made. Physical size distributions can be characterized well by a trimodal model consisting of three additive log-...
متن کاملUltrafine particle deposition in subjects with asthma.
Ambient air particles in the ultrafine size range (diameter < 100 nm) may contribute to the health effects of particulate matter. However, there are few data on ultrafine particle deposition during spontaneous breathing, and none in people with asthma. Sixteen subjects with mild to moderate asthma were exposed for 2 hr, by mouthpiece, to ultrafine carbon particles with a count median diameter (...
متن کاملNon-targeted effects induced by ionizing radiation: mechanisms and potential impact on radiation induced health effects.
Not-targeted effects represent a paradigm shift from the "DNA centric" view that ionizing radiation only elicits biological effects and subsequent health consequences as a result of an energy deposition event in the cell nucleus. While this is likely true at higher radiation doses (>1 Gy), at low doses (<100 mGy) non-targeted effects associated with radiation exposure might play a significant r...
