| 摘 要： | 为研究盘锦市秋冬季节大气PM_(2.5)中碳组分的污染特征和来源,于2016年10月和2017年1月采集盘锦市3个点位PM_(2.5)样品,通过OC/EC比值法,EC示踪法以及主成分分析法对PM_(2.5)中碳组分进行污染特征分析及来源解析.结果表明,盘锦市秋冬季节PM_(2.5)浓度均超过环境空气质量标准(GB 3095-2012)二级标准,秋季OC和EC的平均浓度为10.02μg·m~(-3)和3.91μg·m~(-3),冬季为16.04μg·m~(-3)和5.62μg·m~(-3);采样期间秋冬季节OC/EC均大于2.0,说明各采样点位在秋冬季均可能存在二次污染,Spearman相关分析及线性拟合可知开发区OC与EC来源复杂,第二中学及文化公园OC和EC可能具有同源性;通过EC示踪法对SOC进行定量估算,得出秋季SOC浓度为7.21μg·m~(-3),冬季为23.07μg·m~(-3),对结果进行不确定性分析,可知秋冬季节SOC不确定性的绝对误差和相对误差均在可接受范围内;通过主成分分析得出盘锦市秋冬季节PM_(2.5)中碳组分主要来源于煤烟尘,生物质燃烧以及机动车尾气.
