Air pollution is no longer a matter of discussion limited to intellectual circle only, rather it has become a matter of great concern for us people who live in the urban areas and is increasingly changing the ways we live. Auto fuel exhausts, industrial emissions, smells of chemicals from small factories and workshops, and so on, there is just no escape. People are restricting their outdoor activities including walking, jogging, or cycling when the air quality index ( AQI ) is high.

Diseases like asthma, lung cancer, heart diseases, etc. generally occupy the center stage when we talk about the harmful effects of air pollution on our health but recent reports suggest that the physical health problems are not all, psychologists are reporting of the growing number of mental problems caused by the air pollution.
