The presence of harmful gases, aerosols, particulates and biological molecules in the atmosphere is termed as air pollution. Air pollution poses serious health risks to humans such as strokes, asthma, heart disease and lung cancer. Animals and plants are also adversely affected by it. Both natural and anthropogenic sources are responsible for air pollution. Wildfires, dust storms and volcanic activity are some of its natural sources. The use of fossil fuels, production of fumes, water deposition in landfills, etc., are a few anthropogenic sources which can lead to air pollution. These activities result in release of carbon dioxide, oxides of sulfur, chlorofluorocarbons and nitrogen oxide. Air pollution can be controlled through the use of electric vehicles and switching to renewable sources of energy. From theories to research to practical applications, case studies related to all contemporary topics of relevance to this field have been included in this book. It aims to shed light on some of the unexplored aspects of air pollution and the recent researches in this field. This book is a vital tool for all researching or studying air pollution as it gives incredible insights into the prominent issues and concerns related to air pollution.
