The purpose of our investigation was to examine the mass concentrations of EC, OC and TC (EC + OC) in PM(10), PM(2.5) and PM(1) particle fractions. Daily PM(10), PM(2.5) and PM(1) samples were collected at an urban background monitoring site in Zagreb during winter 2009. Average OC and EC mass concentrations were 11.9 and 1.8 μg m(-3) in PM(10), 9.0 and 1.4 μg m(-3) in PM(2.5), and 5.5 and 1.1 μg m(-3) in PM(1). Average OC/EC ratios in PM(10), PM(2.5), and PM(1) were 7.4, 6.9 and 5.4, respectively.
我们的研究目的是检测 PM(10)、PM(2.5)和 PM(1)颗粒部分中 EC、OC 和 TC（EC+OC）的质量浓度。2009 年冬季，在萨格勒布的城市背景监测点采集了每日 PM(10)、PM(2.5)和 PM(1)样本。在 PM(10)中，OC 和 EC 的平均质量浓度分别为 11.9 和 1.8 μg m(-3)，在 PM(2.5)中分别为 9.0 和 1.4 μg m(-3)，在 PM(1)中分别为 5.5 和 1.1 μg m(-3)。PM(10)、PM(2.5)和 PM(1)中的 OC/EC 比值分别为 7.4、6.9 和 5.4。
