Fine and ultrafine particles in the Zürich (Switzerland) area
On occasion of the project YOGAM (year of gas phase and aerosol measurements), the spatial and temporal variation of selected aerosol and gas phase parameters was assessed for the Z ¨ urich (Switzerland) area with a new mobile pollutant measurement laboratory. This assessment based on on-road measurements along a specified route 5 on selected days during different seasons in 2001/2002, covering...
متن کاملUltrafine 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 کاملCoarse and fine particles but not ultrafine particles in urban air trigger hospital admission for asthma in children.
BACKGROUND Short-term exposure to air pollution can trigger hospital admissions for asthma in children, but it is not known which components of air pollution are most important. There are no available studies on the particular effect of ultrafine particles (UFPs) on paediatric admissions for asthma. AIM To study whether short-term exposure to air pollution is associated with hospital admissio...
