The residents of fast-growing cities in Iran, India and Pakistan are particularly threatened by death from air pollution. According to the findings of the World Health Organization (WHO), there is exposure to particulate matter, which sits on the respiratory system, the world's worst.
Los Angeles on the other hand, the air is cleanest - partly because of lower population density and favorable wind conditions - in the cities of Canada and the United States. This is from a show on Monday in Geneva on published statistics air pollution.
Fine dust particles in the air increase, according to WHO, the risk of acute and chronic diseases of the respiratory system - such as pneumonia or lung cancer - as well as circulatory problems. In total, data were selected from 1100 cities in 91 countries, but many are several years old. Was measured by an air pollution, especially fine particles of ten microns (PM10) or less.
WHO estimates that annually more than two million people die from polluted air. For 2008, the date of the most recently published statistical figures, 1.3 million deaths in the urban air pollution reduced. If the strict WHO rules for air pollution has already been applied, would have almost 1.1 million deaths can be prevented, the organization writes.

In Wolfsburg, the air was of such inspection, the cleanest of all 59 German cities studied. There are 17 particles found in a cubic meter of air (2008). Some 300 cities worldwide had better air.
The WHO has guidelines several years ago spent on air pollution in cities, which are but little respected worldwide. The recommendation is a maximum of 20 particles per cubic meter on average. In many cities, but they lie in more than 300 As a major contributor to apply this information to the city traffic, small industrial plants, the burning of biomass and coal for cooking and heating, and coal power plants.
