Abstract

In this study, temporal and spatial variations of the atmospheric concentrations of polychlorinated-p-dibenzo dioxin (PCDDs) and polychlorinated dibenzofuran (PCDFs) congeners were investigated in Istanbul at three different locations. The highest average concentration (3481fg/m3) was observed at the sampling location which is characterized by mixed source groups during colder months. The lowest average concentration (749fg/m3) was observed at sampling station which is characterized by semi-urban characteristics. ∑PCDD/F concentration showed seasonal variation in this study. The highest average concentration was determined to be 4373fg/m3 in winter while the lowest average concentration was determined to be 498fg/m3 in summer. © 2013 Elsevier B.V.
