Pollution is now a common place term that our ears are familiar to. We hear about the various forms of pollution and read about it through the mass media. Air pollution is one such form that refers to the contamination of the air, irrespective of indoors or outside. A physical, biological or chemical alteration to the air in the atmosphere can be termed as pollution. It occurs when any harmful gases, dust, smoke enters into the atmosphere and makes it difficult for plants, animals and humans to survive as the air becomes dirty. Vehicles crowding roadways, power plants pumping smoke and chemicals from consumer products have many people thinking about air pollution and how it affects the planet. Air pollution is a complicated problem with many causes and effects and few solutions. The two main forms of outdoor air pollution include particulate matter, sometimes called black carbon pollution, and noxious gases. Burning fossil fuels to power vehicles, homes and industrial plants releases tiny particles of matter into the air. The sustainment of all things living is due to a combination of gases that collectively form the atmosphere; the imbalance caused by the increase or decrease of the percentage of these gases can be harmful for survival. The Ozone layer considered crucial for the existence of the ecosystems on the planet is depleting due to increased pollution. Global warming, a direct result of the increased imbalance of gases in the atmosphere has come to be known as the biggest threat and challenge that the contemporary world has to overcome in a bid for survival. The particulate matter and noxious gases floating in the atmosphere can trap solar heat in a process known as the greenhouse effect. The effects of Air pollution are alarming. They are known to create several respiratory and heart conditions along with Cancer, among other threats to the body. Several millions are known to have died due to direct or indirect effects of Air pollution. Children in areas exposed to air pollutants are said to commonly suffer from pneumonia and asthma. This book covers principles and practices of air pollution such as causes, analysis and control.
