This study was conducted to investigate the content of heavy metals remaining in the accumulated dust around the house and road side in Taegu city.
Samples were collected from 74 sites-eleven industrial, nine busy street, six commercial, fifteen road side, eleven park-during July to September 1991. Control was 4 samples from greenbelt. The weight of a sample was ten grams and each
samples was analysed by atomic absorption spectrophotometer(Mdel, IL. 551).
It was noted that the average content of heavy metals in all areas was 3.929±8.018ppm in lead, 0.444±0.273ppm in cadmium, 73.425±8.469ppm in zinc, 16.297±9.868ppm in copper and 92.774±50.332ppm in iron.
When the average content of heavy metals of areas except a greenbelt of Taegu city was compared with control, it was noted that the content of all heavy metals except iron was higher than that of control. The areas that the average
content
was higher than that of
controls in statistical significance were industrial in lead, all areas except the park in cadmium, zinc and copper, industrial and residental area in iron.
When a slum of residental area was compared with apartment houses of that, the content of all heavy metals of a slum was higher than that of apartment, but the statistical significance was noted in zinc and iron.
