Spatial-Temporal Variations of Atmospheric PM10 over Zhuhai

  • 摘要: 选取2000年6月-2001年5月珠海空气中PM10的观测数据,分析其在3个监测点(香洲、前山和吉大)的时空演变特征.结果表明,珠海PM10的年均质量浓度为40 μg/m\+3(校正后为52 μg/m\+3),低于国家PM10的二级质量标准,与国内外其他城市相比,珠海PM10相对较低,表明珠海的大气颗粒物污染轻微.2001年4月14,15日珠海PM10日均值显著增高,达到92,127 μg/m\+3,对比香港及北方粉尘源区的颗粒物浓度及气团轨迹分析结果可知,珠海也受到了北方沙尘暴的影响.3个站点的PM10月均质量浓度变化主要表现为夏、秋季低,冬、春季高.珠海市大气PM10的日变化形式以白天高、夜晚低为主.
