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 (3481 fg/m(3)) was observed at the sampling location which is characterized by mixed source groups during colder months. The lowest average concentration (749 fg/m(3)) 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 4373 fg/m(3) in winter while the lowest average concentration was determined to be 498 fg/m(3) in summer.
本研究在伊斯坦布尔三个不同地点调查了大气中多氯二苯并对二恶英（PCDDs）和多氯二苯并呋喃（PCDFs）同系物浓度的时间和空间变化。在较冷月份具有混合源组特征的采样地点观察到最高平均浓度（3481 fg/m3）。在具有半城市特征的采样站观察到最低平均浓度（749 fg/m3）。在这项研究中，∑PCDD/F 浓度表现出季节性变化。冬季最高平均浓度为 4373 fg/m3，夏季最低平均浓度为 498 fg/m3。
