摘要
基于山东省各城市碳组分污染特征研究相对缺乏的现状,本研究选取沿海城市代表青岛和内陆城市代表济南分三个季度进行采样,并采用热光投射法对PM_(2.5)中的碳组分进行分析,以获得山东省沿海和内陆城市PM_(2.5)中碳组分污染特征;并通过分析OC/EC比值及OC和EC的相关性,初步判断两地含碳气溶胶来源;通过估算SOC的浓度,了解两地市二次含碳气溶胶的生成情况。研究结果表明,2014年,青岛和济南PM_(2.5)浓度分别为86.34μg/m~3、145.10μg/m3;OC浓度分别为12.23μg/m~3、16.26μg/m~3;EC浓度分别为1.76μg/m~3、2.43μg/m~3,内陆城市济南PM_(2.5)及碳组分污染程度重于沿海城市青岛,两地市均以采暖季污染程度最重。两地市OC、EC相关性均较为显著,OC和EC有较为相近的一次污染来源。两地市OC/EC比值均大于2,表明均受到了二次有机碳SOC的污染。
