Air Pollution
Air pollution is a serious problem in Ulan Bator, especially in winter. Concentrations of certain types of particulate matter (PM10) regularly exceed WHO recommended maximum levels by more than a dozen times. They also exceed the concentrations measured in northern Chinese industrial cities. During the winter months, smoke regularly obscures vision and can even lead to problems with air traffic at the local airport.
Sources of the pollution are mainly the simple stoves used for heating and cooking in the city's yurt quarters, but also the local power plants (fueled on coal). The problem is compounded by Ulaanbaatar's location in the a valley between relatively high mountains, which shield the city from the winter winds and thus obstruct air circulation.
Ulaanbaatar's residents are very aware of the city's pollution problems (during the winter months, pollution levels and their relation to WHO recommended levels are regularly reported on TV, in a manner similar to weather reports) and ways to amend the situation have been discussed for years, however no easy solution has been found yet.

Famous quotes containing the words air and/or pollution:
“The sumptuous age of stars and images is reduced to a few artificial tornado effects, pathetic fake buildings, and childish tricks which the crowd pretends to be taken in by to avoid feeling too disappointed. Ghost towns, ghost people. The whole place has the same air of obsolescence about it as Sunset or Hollywood Boulevard.”
—Jean Baudrillard (b. 1929)
“Like the effects of industrial pollution ... the AIDS crisis is evidence of a world in which nothing important is regional, local, limited; in which everything that can circulate does, and every problem is, or is destined to become, worldwide.”
—Susan Sontag (b. 1933)
