对阿伊卡工业城镇的城市空气颗粒物（悬浮颗粒和沉降粉尘）以及Söderberg铝厂和燃煤电厂排放的粉尘进行了多环芳烃（PAH）含量（液相色谱法）和致突变性（沙门氏菌微粒体试验）分析。对来自帕帕（一个规模类似但没有太多重工业的城镇）的空气颗粒物的相同参数进行了分析，并与来自阿伊卡的参数进行了比较。阿伊卡的粉尘含量、多环芳烃浓度和致突变力均高于帕帕。空气中颗粒物的致突变性表现出明显的季节性，冬季最大，夏季最小。空气的致突变能力与苯并[a]芘（BP）和PAH的含量在阿伊卡，但不是在Pápa的相关性很好。Pápa样本中的可浸提有机物质和致突变效力（按单位数量的空气悬浮颗粒物计算）较高。在沉降灰尘的情况下，两个城镇之间也观察到类似的差异。关于排放粉尘，铝厂排放物比发电厂排放物对城市空气的致突变性要大得多，发电厂排放物是阿伊卡空气粉尘污染的主要成分。
Urban air particulates (suspended particles and settling dusts), as well as dusts emitted by a Söderberg aluminium production plant and a coal-burning power plant, in the industrial town of Ajka were analysed for polycyclic aromatic hydrocarbon (PAH) content (liquid chromatography) and mutagenicity (Salmonella microsome test). The same parameters for air particulates from Pápa (a town of similar size without much heavy industry) were analysed and compared to those from Ajka. The dust content, PAH concentration and the mutagenic potency of the air in Ajka were higher than in Pápa. Mutagenicity of airborne particulates showed a clear seasonality with a winter maximum and a summer minimum in both towns. The mutagenic potency of air correlated well with the benzo[a]pyrene (BP) and PAH content in Ajka but not in Pápa. The amounts of extractable organic material and mutagenic potency, as calculated for unit quantity of airborne particulate matter, were higher in the Pápa samples. Similar differences between the two towns were observed in the case of deposited dust. As regards the emission dusts, the aluminium plant emissions are responsible for much more of the mutagenicity of the urban air than the power plant emission, which is the main component of air dust pollution in Ajka.
