Short-term personal and outdoor exposure to ultrafine and fine particulate air pollution in association with blood pressure and lung function in healthy adults

Studies reporting on associations between short-term exposure to outdoor fine (PM 2.5 ), and ultrafine particles (UFP) blood pressure lung function have been inconsistent. Few studies characterized by personal monitoring, which especially for UFP may resulted in substantial measurement error. We investigated the association 24-h average UFP, PM , soot dose health parameters function. further assessed concentrations measured at a central monitoring site near residences these outcomes. performed three measurements 132 healthy adults from Basel (Switzerland), Amsterdam Utrecht (the Netherlands), Turin (Italy). Monitoring of each subject was conducted different seasons one-year study period. Subject's activity levels associated ventilation rates were using actigraphy calculate inhaled dose. After session, measured. Contemporaneously with measurements, subject's residential address research area. Associations outcomes tested linear mixed effect models.
