| 摘 要： | 利用2016年6~7月在青岛采集的总悬浮颗粒物(TSP)样品,分析了其中不同形态磷的浓度,讨论了夏季气溶胶中总磷(TP)、溶解态磷(DP)、溶解态无机磷(DIP)和溶解态有机磷(DOP)的分布特征及来源,并估算了大气P的沉降通量.结果表明,夏季青岛大气气溶胶中TP的浓度为(49.3±30.6)ng·m~(-3),其中DP浓度为(15.5±10.4)ng·m~(-3),对TP的贡献为30.9%±11.0%.DP中以DIP占主导,其贡献平均约为60%.气溶胶中不同形态P的来源分析结果显示,夏季青岛气溶胶中P的来源复杂,受地壳源、人为源、生物质燃烧、农业施肥等多种源的共同影响.其中TP的38%来自土壤源的贡献,农业活动源和工业源的贡献分别为20%左右;DP中DIP主要受到农业活动源及燃烧源的影响,其贡献分别为51%和24%;DOP主要来源于土壤源及农业活动源,其贡献分别为41%和27%.观测期间,大气TP的干沉降通量为(51.7±31.7)μg·(m~2·d)~(-1),其中DP对TP干沉降通量的贡献为23.2%±8.2%.DP中DOP有重要贡献,约为DP干沉降通量的40%.DP的干沉降通量可支持黄海(0.5±0.3)mg·(m~2·d)~(-1)浮游植物碳的生产,对新生产力的贡献约为1%.
