Millions of people are being exposed to harmful levels of air pollutants caused mainly by emissions from industrial and domestic activities and from motor vehicles involving the combustion of fossil fuels. Reduced visibility, damage to monuments and buildings, and many other such consequences indirectly affect our quality of life, ultimately damage to ecological systems. This Book represent state of knowledge regarding the nature and effects of photochemical pollution and draws some conclusions concerning the setting of goals for oxidant concentrations and the most effective strategies for smog control. The nature of Photochemical Smog is explored with some emphasis on the limitations of ozone as an indicator of pollution. This book provides an essential guide to researchers, it offers: affects of Photochemical Smog on current Society. Simply explained, Photochemical Smog is an important book bringing together diverse viewpoints from Environmentalist, state agencies and regulators, for all who wish to save Earth with quality Life.
