Health effects of ambient ultrafine (nano) particles in haze

Are ultrafine ambient particles health hazards?

[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...

Deposition of ultrafine (nano) particles in the human lung.

Increased production of industrial devices constructed with nanostructured materials raises the possibility of environmental and occupational human exposure with consequent adverse health effects. Ultrafine (nano) particles are suspected of having increased toxicity due to their size characteristics that serve as carrier transports. For this reason, it is critical to refine and improve existing...

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...
