Abstract

The content of polycyclic aromatic hydrocarbons (PAH) in a Søderberg prebaked aluminum reduction plant and an anode plant was studied. Both stationary and personal sampling were used, and the samples were analyzed by glass capillary gas chromatography. In many samples more than 30 PAH and heterocyclic compounds were identified. Comparison of the results from the different plants revealed that the atmospheric PAH content was significantly higher in the Søderberg plant than in the others. However, the relative distribution of PAH components (PAH profile) was relatively constant in the prebaked and the anode baking plant, and different in the Søderberg plant. As a consequence of the variation in the pollution level among the different job categories, personal sampling showed a broader range of PAH concentrations than the stationary method.

摘要

对一个 Söderberg 预焙铝还原厂和一个阳极厂中的多环芳烃（PAH）含量进行了研究。采用了固定采样和个人采样两种方式，并通过玻璃毛细管气相色谱法对样品进行分析。在许多样品中，鉴定出了 30 多种 PAH 和杂环化合物。不同工厂结果的比较显示，Søderberg 厂大气中的 PAH 含量明显高于其他工厂。然而，PAH 成分的相对分布（PAH 谱）在预焙厂和阳极焙烧厂中相对恒定，而在 Søderberg 厂中有所不同。由于不同工作类别之间污染水平存在差异，个人采样显示出的 PAH 浓度范围比固定采样方法更广。
