Airborne particulate samples were collected on a glass fiber filter or quartz filter using Hi-volume air sampler from November, 1980 through February, 1983 at a west part of Yahata district, Japan. The concentrations of airborne particulates, polynuclear aromatic hydrocarbons (PAH), heavy metals and dustfall were determined, and mutagenic activities of tarry materials obtained from suspended particulates were also measured. The following results were obtained. (1) The airborne particulate contents were 22.1 - 188 mg/1000 m3 (mean : 74.6 mg/1000 m3), and the values were high in spring and low in summer. (2) PAH contents in airborne particulates were in the following order: benzo(ghi)perylene greater than benzo(a)pyrene greater than benz(a)anthracene greater than chrysene greater than benzo(k)fluoranthene greater than pyrene greater than perylene. PAH contents were higher in winter that in summer. The benzo(a)pyrene contents were 1.97 micrograms/1000 m3 in 1981 and 1.92 micrograms/1000 m3 in 1982. (3) Heavy metals content was about 2.1 - 3.6 higher in winter in comparison with that in summer time. (4) Mutagenic activity showed 90 - 11900 revertants/1000 m3 for TA 98 strain with S-9 mix and 50 - 7190 revertants/1000 m3 for TA 98 strain without S-9 mix. Mutagenic activities for TA 98 with S-9 mix were higher than those for TA 98 without S-9 mix. (5) As a result of the analysis of airborne particulate samples, a significant correlation was observed between mutagenic activities and the concentrations of PAH and heavy metals. These results indicated that the mutagenic survey may be useful as an index for air pollution study.
1980年11月至1983年2月期间，在日本八幡地区西部，使用大容量空气采样器在玻璃纤维滤膜或石英滤膜上采集空气颗粒物样本。测定了空气颗粒物、多环芳烃（PAH）、重金属和降尘的浓度，还测量了悬浮颗粒物中焦油状物质的诱变活性。得到了以下结果。（1）空气颗粒物含量为22.1 - 188毫克/1000立方米（平均：74.6毫克/1000立方米），春季数值较高，夏季较低。（2）空气颗粒物中的PAH含量顺序如下：苯并（ghi）芘＞苯并（a）芘＞苯并（a）蒽＞ Chrysene＞苯并（k）荧蒽＞芘＞苝。PAH含量冬季高于夏季。1981年苯并（a）芘含量为1.97微克/1000立方米，1982年为1.92微克/1000立方米。（3）冬季重金属含量比夏季高约2.1 - 3.6倍。（4）对于TA 98菌株，加S - 9混合液时诱变活性为90 - 11900回复突变体/1000立方米，不加S - 9混合液时为50 - 7190回复突变体/1000立方米。加S - 9混合液的TA 98菌株的诱变活性高于不加S - 9混合液的。（5）通过对空气颗粒物样本的分析，发现诱变活性与PAH和重金属浓度之间存在显著相关性。这些结果表明，诱变调查可能作为空气污染研究的一个指标是有用的。
