World Atlas of Atmospheric Pollution

During the Industrial Revolution especially, cities experienced profound changes in air pollution, see Figure 1. Annual series smoothed with a 21-point binomial filter. A major work, such as this Atlas, would not have been possible if it were not for the generous input from a large number of colleagues and their organizational across the world especially for making data and information available. Contributions to natural forcing associated with aerosols from volcanoes are not included in this figure due to their episodic nature. In fostering international cooperation in the atmospheric sciences the challenge is not simply to promote progress, at scientific and policy level, in each of the separate specialist areas: it is to allow scientists and lay persons alike to stand outside those specialisms and see the wider context. The situation was similar in the New York emissions reduction case, where O3 improvements within New York ranged from about 3 per cent to 15 per cent. Even though Union Carbide accepted moral responsibility, the issue remains unresolved, as many victims are still seeking redress and there are concerns over continued contamination.

Interest in air pollution in the major cities of developing nations, however, is now coming to the forefront of scientific attention and a number of studies have been reported in the literature see for example, Molina and Molina 2002; Baldasano et al. In 1979 there was a small minimum in total ozone over the polar region, surrounded by a crescentshaped maximum. Amazonian fires Destruction of the forests leads to bare 0° soil which releases carbon dioxide adding to the atmospheric burden and enhancing the greenhouse effect. The Forum links together existing regional air pollution control networks from around the globe so that they can better share information, experience and expertise and, in so doing, more effectively tackle air pollution and climate change. The population and traffic trends across the main regions of the world are discussed in Chapter 2, before examining air pollution in different cities around the world.

From the second half of the twentieth century, air pollution problems have also been more global. Vehicle ownership, however, has increased significantly and is projected to grow further in the next two decades, as shown in Figure 2. About 25 per cent of the land surface of the Northern hemisphere is underlain by permafrost. In addition to being unreactive, they are insoluble and accumulate in the atmosphere. There is also an urgent need for good quality data to improve our understanding of the problems of air pollution in large cities in developing nations. The spread of the disease is thus 90 45 0 -45 -90 -180 -90 0 3 6 0 9 12 90 15 25 50 180 75 100 125 Figure 4.

Water will flow out at a faster rate and the water level will adjust downward. These variabilities are caused by complex atmospheric processes and interactions as well as changes in emissions. Other Countries Satellite Observations Figure 3. Arie Haagen-Smit showed, in the early 1950s, that a new type of pollution confronted Los Angeles. Strong winds, however, can cause significant suspension and re-suspension of dust, especially when the ground is dry.

The atmospheric circulation transports this vapour vertically and horizontally to cooler locations where it is condensed as rain or is deposited as snow, releasing the stored heat energy. However, any effective air quality management strategy will require a combination of measures on local, national and regional, if not global levels which are cooperative in nature. The right globe shows the total amount of ozone in a vertical column of the stratosphere. The number of cars per head of population in major cities across the world is increasing, with a marked contrast between the ownership in Asian cities and those in Europe and North America. Atmospheric pollution, therefore, has to be viewed in terms of a variety of anthropogenic sources, including traffic, industrial and domestic.

The transport paths and scales of air pollution transport in the Mediterranean region has been the subject of various projects during the last two decades e. Small animals died and children began to show symptoms where they had been exposed to the emissions. Air pollution across the globe, however, is not only caused by road traffic emissions. These were said to affect the health of the White Friars. For example, Luria et al.

Hundreds of thousands were injured and a bitter debate about causes and responsibility ensued, which often left those affected without proper medical attention or just compensation. It also supports regional networks in their efforts to find cost-effective solutions that promote economic development and help alleviate poverty. However, these primary pollutants can also be subjected to many other complex processes that can transform them into harmful secondary products. The seasonal variations in global warming are shown in Figure 4. By the beginning of the last century most of the highly populated cities were in the developed countries, whereas by 2000 most were in the developing regions.

In the subtropics, precipitation has decreased by 2—3 per cent. The major eruptions of August 1883 led to dust spreading around the world and gave rise to spectacular sunsets Austin 1983. Role of Ozone Tropospheric O3 is a direct greenhouse gas. He saw the need for emissions controls on automobiles. Statistical Analysis of Measurements The spatial extent of a pollutant airshed — the domain over which significant regional transport occurs — may be estimated through statistical analysis of observed values at different times and 40 While a statistical approach provides important insights into understanding observations, it does not explicitly take physical transport processes into account. Note that marginal classified areas have not been shown. Ireland Norway Finland Netherlands Japan Slovenia United Kingdom Sweden Spain Belgium France Malta Austria Switzerland Australia Brunei Germany New Zealand Portugal Canada Iceland Italy Luxembourg United States 0 Country Figure 2.
