松花江吉林市江段江水中多环芳烃来源的研究

为研究松花江吉林市江段中多环芳烃来源,采集了松花江吉林市江段2013年5月(平水期)、2013年8月(丰水期)和2014年1月(枯水期)的江水、沉积物、废水、降尘、降水及地表径流样品,测定了其中16种多环芳烃的含量,利用主成分分析法对降水中多环芳烃的来源进行分析,同时计算松花江吉林市江段中多环芳烃的输入通量。结果表明:江水中多环芳烃来源较为广泛,不同水期江水中多环芳烃来源有一定的差别,但所有水期石油源和交通源均是江水中多环芳烃的主要来源,平水期和丰水期沉积物中PAHs的主要来源是燃烧源,其次是石油源。松花江吉林市江段的多环芳烃最主要是通过上游来水的方式进入到江水中,其它输入方式按输入通量由多到少依次为废水排放、降尘、降水、地表径流。

Study on the sources of Polycyclic Aromatic Hydrocarbons in the Songhua River in Jilin City

In order to analyze the sources of polycyclic aromatic hydrocarbons in Songhua River in Jilin City, this article collected river water, sediment, waste water, dust, rainfall and surface runoff samples of Jilin Songhua river in May 2013(flow period), August 2013(wet period) and January 2014 (dry period).This article Analyzed the content of 16 kinds of polycyclic aromatic hydrocarbons. Using Principal Component Analysis (PCA) to analyze the source of polycyclic aromatic hydrocarbons, and calculate the Songhua River in Jilin city PAHs input flux. Results showed that the river source is relatively broad, PAHs in the different water period river have certain difference source, but the main source of PAHs in water in all the water period is oil source and traffic source. The main source of PAHs in sediment of flow period and the wet period is burning and oil. The main way of PAHs entering the Jilin Songhua river is through the upstream water. The other way, in turn, is waste water emissions, dust, rainfall and surface runoff, according to the quantity of input flux.
