Abstract
Indoor air quality is important to human health because we spend more than 80% of our time indoors. Occupants of indoor environments may be exposed to a variety of pollutants originating from human activities or presence in the home, combustion from heating and cooking, consumer products, furnishings, building materials and outdoor air. The quality of indoor air depends on the quality of outdoor air and on the emissions of indoor sources.
One may feel the effects of an indoor pollutant immediately after the, or the problem may not be realized until years later. Immediate effects of an indoor air pollutant include irritation of the eyes, ear and throat, headaches, dizziness and fatigue where as acute cough respiratory problems and lung cancer may be felt after a long duration of exposure. The prime factors affecting human health are nature of the pollutants, concentration of the pollutants duration of the exposure, status of health of the receptor and age.
A large number of studies have been conducted to evaluate the indoor air quality of offices, industries, commercial places, hospitals, schools etc. but a little is done on the indoor air quality of residential buildings. Thus with the increasing thrust on air pollution a thought of evaluating and analyzing the indoor air quality in homes was felt. The major goal of this research was to gain knowledge about the various pollutant their concentration, exposures and effects that are important for people's perception of indoor climate.
Thus the study was undertaken with the following objectives:
1. To analyze the indoor air quality (IAQ) of the residential buildings of Udaipur city.
2. To study the impact of IAQ on health of the family members.
3. To compare the existing IAQ with the ASHRAE / WHO Standards.
4. To develop a package of practices on the requirements of an adequate indoor air quality.
Indoor air quality depends on factors such as temperature, humidity, odours, air movement and ventilation, bioaerosols and volatile organic hydrocarbons. In some sealed buildings with the mechanical ventilation, there is a range of complaints, such as symptoms of eye and nose irritation, nasal congestion, sore throat, fatigue, malaise and headache, that are referred to as “sick building syndrome” (Burge and Hoyer, 1990).
