【摘要】 对青岛海岸大气气溶胶的观测分析表明 ,青岛沿海大气气溶胶普遍存在着氯亏损 ,氯亏损受燃煤排放、大气中酸性气体、气象条件、温度、光照等多种因素的影响 ,氯亏损随粒径变化也因时间、季节有所不同 .青岛沿海大气气溶胶在粒径 <2 5μm、粒径 2 5— 10 μm、粒径 >10 μm三个粒径段内氯亏损的变化范围分别为氯富集 3 3 %到氯亏损 88 1% ,氯亏损 41 1%—6 6 1% ,氯亏损 2 2 6 %— 77 4% .更多还原

【Abstract】 The atmospheric aerosol in the coastal of Qingdao was collected and analyzed.It was found that many factors,such as coal burning emissions,acidic gases in the atmosphere,meteorological conditions,temperature,and illumination,affect chloride depletion of coastal atmospheric aerosol.The change of chloride depletion with the aerosol diameter varied with time and season.In Qingdao coastal atmosphere,the chloride depletion for PM 2.5 ,PM 2.5—10 ,PM >10 ranged from chloride enrichment of 3.3% to chloride depletion of 88 1%, chloride depletion of 41.1%—66.1% chloride depletion of 22.6%—77.4%,respectively.更多还原
