Abstract

|
In recent years there has been a growing concern about indoor air quality. Studies on the health effects by indoor air pollutants indicate that even average levels of some pollutants are cause for substantial concern, while in some buildings, levels of pollutants are of great cencern. In fact exposure to some indoor pollutants has the potential to cause thousands of deaths each year, e.g. carbon monoxide poisoning in China and Korea. The air quality in an indoor space depends on the outdoor air quality, on the presence and strength of emission from indoor sources, on the ventilation rate and efficiency.
Authors recognized the importance of the indoor air quality, specially the heavy metal concentration which comes out from fossil fuel combustion, tobacco smoke, and some other sources like building materials.
Indoor air was passed through millipore membrane filter by means of personal air sampler (21/min), digested with HNO3, and analyzed Fe, Mn, Cd, Cu, Pb, and Zn by Atomic Absorption Spectrophotometer. The value of 1.523ppm of Fe was highest heavy metal concentration in indoor air by comparing outdoor air Fe concentration of 0.0894ppm. The Pb mean value of 0.122ppm was detected in restaurant using petroleum stove.
The other metals were found to be trace amounts.
