ABSTRACT

Instrumental neutron activation analysis was used to measure the concentrations of 27elements associated with respirable particulate matter (PM10) that were collected from theThird and Fourth Industrial Complex Area of Daejeon City. The distribution patterns ofelements were clearly distinguished with their concentrations varying across more than fourorders of magnitude. The mean for Al were recorded to be the highest value of 1,527 ng/m3,while that for In showed the lowest value of 0.1 ng/m3. If compared in terms of enrichmentfactors, it was found that certain elements (e.g., As, Br, Cl, Cr, I, In, Sb, Se, and Zn) are enrichedin PM10 samples of the study site. The results of factor analysis indicated six factors withstatistical significance, which may exert dominant controls on regulating the elementalconcentration levels in the study area.
