(Varese) ITAL Y 1. Introduction Worldwide, there is an ever
increasing interest and concern about the destructive effects of
air pollution on man's ecosystem. The growing awareness of these
effects has revealed the need to take adequate measures to minimize
the emission of air polluting products. The two most important
contaminants, occurring in the largest concentrations and
quantities, are sulphur dioxide and nitrogen oxides. Both
pollutants are formed mainly during the combustion of fossil fuels,
particularly by power stations and traffic. The effects of air
pollution caused by these two contaminants have already been
studied for several decades and measures to protect the environment
against their adverse effects are now operative in many countries.
The present volume contains the proceedings of a Eurocourse held in
Ispra in September 1990. The course was meant to give an overview
of present knowledge concerning the emission sources and
quantities, to cover features of present legislation and to give a
survey of the most important modern abatement techniques for S02
and NOx. It was mainly addressed to higher and medium management in
the power, chemical and similar industries, particularly from those
countries where the fight against air pollution is still in its
infancy. Obviously, it was not possible to cover completely the
whole range of subjects during the limited duration of a
Eurocourse.
