Ultrafine particles in cities.
Ultrafine particles (UFPs; diameter less than 100 nm) are ubiquitous in urban air, and an acknowledged risk to human health. Globally, the major source for urban outdoor UFP concentrations is motor traffic. Ongoing trends towards urbanisation and expansion of road traffic are anticipated to further increase population exposure to UFPs. Numerous experimental studies have characterised UFPs in in...
متن کاملCommentary: inflamed about ultrafine particles?
Ambient air pollution has been linked to exacerbation of cardiovascular disease morbidity and mortality. 1 These associations have been strikingly robust and range from the observation of coronary heart disease exacerbation within hours of exposure to an increased risk of ischaemic heart disease mortality for subjects chronically exposed to elevated concentrations of ambient particles. Two main...
متن کاملSurgical smoke and ultrafine particles
BACKGROUND Electrocautery, laser tissue ablation, and ultrasonic scalpel tissue dissection all generate a 'surgical smoke' containing ultrafine (<100 nm) and accumulation mode particles (< 1 mum). Epidemiological and toxicological studies have shown that exposure to particulate air pollution is associated with adverse cardiovascular and respiratory health effects. METHODS To measure the amoun...
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...
