Opis

At present, roughly half of the world's population lives in urban centers. There are now more than 20 cities with a population of over 10 million inhabitants, compared to less than 5 about 50 years ago. This tendency toward urbanization is expected to continue, particularly in the developing world. A consequence of this growing trend is that millions of people are being exposed to harmful levels of urban air pollutants caused mainly by emissions from motor vehicles and from industrial and domestic activities involving the combustion of fossil fuels. The driving force for the design and implementation of emission control strate- gies aimed at improving air quality has been the protection of the health of the population in urban centers. There are, however, other consequences of the pres- ence of air pollutants besides the direct effect on human health. Reduced visibil- ity, damage to monuments and buildings, and many other such consequences indirectly affect our quality of life. Another set of consequences involves damage to ecological systems. In fact, the nature of "photochemical smog" was first uncovered in the 1950s in connection with observations of its harmful effects on crops and plants in the vicinity of Los Angeles.

Recenzje

From the reviews:

"The book makes an important contribution to the development of regulations and strategies designed to control air pollution. It provides an excellent starting point for all those interested in the topic of air pollution and its effects on forests. The book’s strength lies in the extensive collection of case studies which clearly depict the impact of pollutants on the species analysed as well as the ecological consequences of such exposure."
