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...

standard model. The hypothetical particles are assumed to be pair-produced in pp̄ collisions giving a signature of two reconstructed muon-like objects with high invariant mass and time-offlights indicative of heavy particles. Since no excess over background is observed, cross-section limits for the pair-production of stable staus and charginos are set. Mass limits of 140 GeV for a higgsino-like ...

1885-5857/$ – see front matter 2011 Sociedad Esp doi:10.1016/j.rec.2011.05.006 Numerous epidemiological studies support the association of exposure to air pollution with adverse health effects leading to enhanced morbidity and mortality of considerable significance. In fact, the World Health Organization ranks it as the 13th leading cause of worldwide mortality. Cumulative evidence over the las...
