Polycyclic aromatic hydrocarbons (PAH) and particulates in the work atmospheres of the potrooms and anode paste plant of an aluminum reduction plant were determined by stationary and personal sampling and a glass capillary gas chromatographic method. The relative distribution of PAH (PAH profile), the fraction of PAH on particulates, and the ratio between particulate and gaseous PAH were also determined. The PAH profile was found to be similar to that found for another aluminum plant. The PAH fraction of particulate matter was generally between 1 and 4%, and the ratio between particulate and gaseous PAH in the potrooms varied from 0.2 to 1. The occupational exposures were determined from an analysis of a total of 167 personal samples. For most job categories, the geometric mean of the exposure values was higher than 40 microg/m3, spike pulling having the highest exposure of the categories measured.
多环芳烃（PAH）和在铝还原厂的电解车间和阳极糊车间的工作环境中的颗粒物质，通过固定和个人采样以及玻璃毛细管气相色谱法来测定。还确定了 PAH 的相对分布（PAH 分布）、颗粒物质上的 PAH 部分，以及颗粒物质和气态 PAH 之间的比值。发现 PAH 分布与另一座铝厂的相似。颗粒物质中 PAH 部分通常在 1%至 4%之间，而在电解车间中，颗粒物质和气态 PAH 之间的比值从 0.2 到 1 不等。职业暴露是从总共 167 个个人样本的分析中确定的。对于大多数工作类别，暴露值的几何平均值高于 40μg/m3，在测量的类别中，拉冒口的暴露最高。
