Billions of tons of desert dust move through the atmosphere each year. The primary source
regions, which include the Sahara and Sahel regions of North Africa and the Gobi and Takla …

Since the London fog of 1952, in which more than 4000 people were killed in 4 days, the
combined efforts of scientists from several disciplines, including those from the …

In order to evaluate the toxicity of TiO2 particles, the acute toxicity of nano-sized TiO2
particles (25 and 80nm) on adult mice was investigated compared with fine TiO2 particles …

Titanium dioxide is frequently used in the production of paints, paper, plastics, welding rod-
coating material, and cosmetics, because of its low toxicity. However, recent studies have …

Background The mechanisms governing the correlation between exposure to ultrafine
particles and the increased incidence of cardiovascular disease remain unknown. Ultrafine …

Background Air pollution has been associated with impaired health, including reduced lung
function in adults. Moving to cleaner areas has been shown to attenuate adverse effects of …

Background Although the mechanisms of airborne particulate matter (PM) related health
effects remain incompletely understood, one emerging hypothesis is that these adverse …

The link between elevated concentrations of ambient particulate matter (PM) and increased
mortality has been investigated in numerous studies. Here we analyzed the role of different …

Background: Consistent evidence has indicated that air pollution increases the risk of
cardiovascular diseases. The underlying mechanisms linking air pollutants to increased …
