Abstract:
This study identified characteristics of heavy metals in ambient total suspended particulates (TSP) and air pollutants (PM(10), CO, NO(x), SO(2) and O(3)) collected on clear and misty days at an urban-residential area and an industrial area in the largest industrial city, Korea, for one-year study period. Average concentrations of TSP at the urban-residential (130 μg/m(3)) and industrial (141 μg/m(3)) areas on misty days were 1.9-2.1 (p<0.05) times higher than those on clear days. Concentrations of heavy metals in the TSP from both areas on misty days were significantly (p<0.05) higher than those on clear days. In particular, Pb and Mn concentrations on misty days were 2.4-2.6 (p<0.05) and 1.7-1.8 (p<0.05) times, respectively, higher at both areas as compared to clear days. Clear days showed higher correlations between TSP and heavy metal concentrations than on misty days at both areas. Average concentrations of PM(10), CO and NO(2) simultaneously measured at/near the sampling sites on misty days were significantly (p<0.05) higher than on clear days at both areas. Average O(3) and SO(2) concentrations showed a similar increase pattern at only one area.
