    The saying goes that ‘health is wealth’. To put it in another way, the health of the people living in the urban centers is greatly influenced by the quality of air and water in those areas. Consider the ‘air quality standard’ prescribed for particular areas.

    Indian Air Quality Standard (Microgram/ cubic meter)
    Sensitive Industrial Rural and
    Pollutant residential area other areas
    Sulphur dioxide 15 60 80
    Nitrogen dioxide 15 60 80
    Suspended particulate matter 70 140 360
    Lead 0.50 60 120

    Pure air is an essential requirement, as a person breathes 22,000 times a day, inhaling 35 gallons or 16 kilograms of air which he obtains from the oxygen rich atmosphere surrounding the earth. This air gets polluted because some gases like sulphur dioxide, hydrogen sulphide, carbon monoxide, suspended particles etc are added to the air by the natural process.

    The National Ambient air quality standard gives the recommended standard of ambient air quality needed in sensitive, residential and rural areas as well as in industrial estates. Even though Kochi is not a prominent industrial area, when compared to other cities in Kerala, Kochi has more commercial establishments, small-scale industries and other polluting workshops in a given land area than in any other city or district in Kerala.

    The Builders in Kochi are now finding it difficult to manage the air pollution since it is beyond their means. Even people in high rise apartment complexes are now reporting health problems, building designs that will be able to deal with this urban pollution are in at the planning stage and when it fructifies, it will certainly cost much higher, than the built up residential spaces being put up for sale
