- INTRODUCTION
Air pollution is the introduction into the atmosphere of chemicals, particulates or biological materials that causes discomfort, disease or death to humans, damage other living organisms such as food crops, natural environment or built environment (http://en.wikipedia.org/wiki/Air_pollution)
A substance in the air that can be adverse to humans and the environment is known as an air pollutant. Pollutants can be in the form of solid particles, liquid droplets or gases. In addition they may be natural or man-made. Pollutants can be classified as primary or secondary. Usually, primary pollutants are directly produced from a process such as ash from a volcanic eruption, the carbon monoxide gas from a motor vehicle exhaust or sulphur dioxide released from factories. Secondary pollutants are not emitted directly but are formed in the air when primary pollutants react or interact. An important example of a secondary pollutant is ground level ozone-one of the many secondary pollutants that make up phytochemical smog. Some pollutants may be both primary and secondary; that is they are both emitted directly and formed from other primary pollutants (Rao et al., 2007).
