• Background

Atmospheric Pollution keeps the momentum of a hot topic of research from the beginning of industrial revolution. The WHO reports point out that air pollution claims 6.5 million deaths every year. The Increased level of fine particulate matter is associated with mortality and precursor of non-communicable disease epidemic makes the research more diverse and inevitable. The detrimental effect of air pollution poses a threat to babies lives and future. The diverse types of pollutants in the air across different environments make it difficult to determine the extent of air pollution. The use of rapidly disintegrating synthetic materials, fossil fuels, and pesticides coupled with the sealing of buildings for prevention of heat / cold loss resulting in indoor air pollution. Urbanization driven by increasing population results in air quality depletion in regional level, reduced visibility and discoloration to heritage monuments. 88 % of urban population lives in areas exceeding air quality standards. Particulate pollutions are resulted by increased vehicular traffic, industrial activities, energy production, waste incineration, etc. Atmospheric heavy metals, though present in small quantities can exert toxic effects, posing human health risks and long-term burden on the biogeochemical cycling in the environment. The 14 most polluted cities in the world are all located in India. Emissions from industries of developing nations are high due to inadequate pollution control measures.
