Abstract

This study was carried out to assess the present level of atmospheric metals. Five metals-lead, cadmium, chromium, manganese, vanadium-were checked on the industrial(Sasang) and residental area(Daeshindong) in the city of Pusan sampling period was the year of 1986, 1990, and 1994, and the sampling time was 2 days of each site. As the result of comparison with the atmospheric standard of ASHRAE(1980) the average concentrations of lead was above the standard, the average concentrations of chromium was around the standard, and the average concentrations of cadmium and vanadium was below the standard. The average concentrations of manganese was above the standard of industrial environment. And the average concentrations of five metals was higher in the industrial area than the residental area The average concentrations of lead cadmium and chromium showed the increase tendency by the year, and the average concentrations of vanadium showed no change, and the average concentrations of manganese showed the decrease tendency. As a result of correlation analysis, lead and cadmium(r=0.31), vanadium and manganese(r=0.24), vanadium and chromium(r=0.19) showed significance.
