摘　　要：使用振荡天平颗粒物在线监测仪连续监测了邯郸市PM10和PM2.5浓度,分析了2012年7月31日—12月2日4个月内PM10、PM2.5的浓度水平、时变规律和PM2.5/PM10的变化情况.结果表明,监测时段内PM10和PM2.5的日均浓度平均值分别为208.4μg·m-3和99.1μg·m-3,是国家二级标准的1.4倍和1.3倍;浓度超标的天数占总观测天数的61.6%和60.0%,其污染程度与北京、天津相当,属污染较严重的地区.PM2.5/PM10在19.3%~89.8%之间周期性波动,平均值为49.4%,接近北方城市的平均水平.PM10和PM2.5的浓度变化具有很好的正相关性;日均值在4个月中呈现明显的周期性变化和月际波动,10、11月的PM10和PM2.5浓度变化剧烈且大大高于8、9月份.PM10和PM2.5浓度一天中小时均值的变化呈同步的双峰型分布,最高值出现在9：00和20：00左右,最低值出现在15：00~17：00之间.本研究系统分析了夏秋季节邯郸市大气颗粒物污染状况,以期为当地颗粒物污染的控制提供科学依据.Concentrations of PM2.5 and PM10 were continuously observed at our newly constructed environmental monitoring station in Handan of Hebei province using automatic on-line tapered clement oscillating microbalance （ TEOM ） particulate monitor. The concentration level, temporal variation characteristics of PM10, PM2.5 and the variation status of PM2.5/PM10 were analyzed for the four months from July 31 to December 2, 2012. The results show that average daily concentration of PM2.5 and PM10 during the four months are 208.4 μg·m-3 and 99.1 μg·m-3, which are 1.4 and 1.3 times their respective national secondary standard. The percentages of the days exceeding the national secondary air quality standard are 61.6% and 60.0% for PM10 and PM2.5 , respectively. Particulate pollution is serious in Handan, which is similar to that in Beijing and Tianjin. PM2.5/PM10 ranged from 19.3% to 89.8% with the average value of 49.4%, which is close to the average level of northern cities in China. The concentrations of PM2.5 and PMI0 are positively correlated. The daily average concentrations of PM10 and PM2.5 show obvious periodic variations and monthly fluctuations. The average concentrations in October and November arc much higher than in August and September. The diurnal variations of PM10 and PM2.5 concentration show synchronous bimodal distribution. The maximum value appears at about 9 am and 8 pm and the minimum value appears between 3 pm and 5 pm. This study systematically analyzed characteristics of particulate matter pollution in Handan city, providing scientific support for the future controls on the severe local particulate matter pollution.
