| 摘 要： | 对2008年05至11月淮南市5个采样点大气可吸入颗粒物(PM10)样品进行分析,总结了研究区内PM10及其中16种PAHs的浓度特征、季节变化规律和来源解析。研究区内16种PAHs浓度总和的范围在15.20~111.58ng.m-3之间,平均值为40.40ng.m-3,中位数为33.34ng.m-3。PAHs总量的季节变化与采样时环境温度显示出较好的负相关性,即秋季>春季>夏季;运用多环芳烃比值综合判断,淮南市大气PM10中PAHs主要以燃煤和机动车尾气混合来源为主,石油源和木材燃烧来源的贡献较小。

| Abstract: | Inhalable participates samples were collected at five different sampling sites in Huainan city from May to November,2008. The samples were analyzed for PM_(10) and 16 PAHs. Concentrations, seasonal changes and source identifications of PM_(10) and 16 PAHs were illustrated. Concentrations of 16PAHs are 15.20ng·m~(-3)～111 .58ng·m~(-3),average value 64.36ng·m~(-3) and medium 33.34ng·m~(-3). Seasonal concentration of PAHs well displayed negative correlation with the surrounding temperature of sampling time, that is autumn > spring > summer. Several PAHs ratios judged complexly that PAHs in atmospheric PM_(10) in Huainan mainly came from the mixed source of coal combustion and vehicle emission. The contribution of petroleum and wood combustion sources was less. |
