| 摘 要： | 为了探究新乡市PM_(2.5)中δ~(13)C比值的季节性变化特征及其对污染来源的指示作用,于2017年夏冬季节采集PM_(2.5)有效样品91个,并测定了样品中的总碳、水溶性离子和稳定碳同位素比值(δ~(13)C).夏季和冬季的TC浓度平均值分别为11.78μg·m~(-3)和26.6μg·m~(-3).夏季δ~(13)C比值为-27.70‰～-25.22‰其中前14 d的δ~(13)C比值波动较大平均值为-26.96‰,而后16d的δ~(13)C比值相对稳定,平均值为-25.69‰,而且前半月和后半月火点数具有较大差异同时K_(nss)~+浓度与TC质量浓度显著相关(R~2=0.62,P0.01)这说明夏收季节生物质燃烧可能对δ~(13)C比值有显著影响.新乡地区冬季RH与TC/PM_(25)质量比值的显著负相关(R~2=0.68,P0.01),揭示了在霾增长初期以SOA增长为主,而污染期以SIA贡献为主.冬季采样期δ~(13)C比值为-26.72‰～-23.49‰,对霾发展过程中稳定同位素组成的研究发现在霾增长过程中δ~(13)C比值以富集为主,而在霾清除阶段δ~(13)C比值以贫化为主.
