石家庄市开放源颗粒物化学组成特征分析

分析了石家庄市城市扬尘、道路尘、土壤尘、建筑尘四种开放源的粒径组成和无机元素含量,结果表明,四种开放源颗粒物样品中细颗粒物的累积效应更为明显。各种水溶性离子中,阴离子浓度最高的是SO42-,阳离子浓度较高的是Ca2+;存在二次有机碳污染,SOC是颗粒物的重要组成部分;各种元素的含量存在一定差异,Ca、Mg、Al、Si、Fe、K等元素含量较高,受人为污染严重。

Analysis of characteristics and chemical composition of open source particulate matter in Shijiazhuang city

The article analyzes the city dust, road dust, soil dust, building dust the four open source of dust particle size composition and content of inorganic elements in Shijiazhuang. The results showed that the four types of open source of fine particulate matter in particulate sample cumulative effect are more apparent. Various kinds of water soluble ion, anion SO42- concentrations is highest, cationic Ca2 concentration is higher; There are secondary organic carbon pollution, SOC is an important component of the particulate matter; The content of various elements exist certain differences, Ca, Mg, Al, Si and Fe, K element content is higher, the man-made pollution is serious.
