摘要:

为了调查研究我国大面积不同流域河流系统中多环芳烃分布特征以及不同地区之间的来源差异,选择了分别代表中国中部、西部和东北部的长江武汉段、涪江及松花江为研究区域,测定了河流水体中16种优先PAHs的含量,并进行了其污染来源识别。结果表明,16种多环芳烃含量范围为N.D ~317.56 ng/L,最高值出现在长江武汉段;在16种多环芳烃单体中,不同地区呈现出不同的组成特征,涪江和松花江以低环PAH组成为主,而长江武汉段高环PAH含量增加;其组分含量高低及特征比值分析结果显示松花江和涪江的来源主要是燃烧源,而长江武汉段来源复杂。

Abstract:

In order to find out the PAHs distribution characteristics and differences of origins in different drainage areas all over China, we chose Fujiang, Songhuajiang, and the middle reaches of the Yangtze river as the aim area to represent middle, western and northeastern China, respectively. In this study, the distribution of 16 priority PAHs in the river water samples along the rivers was studied. The results showed that the concentration of PAHs ranged from N.D. to 317.56 ng/L and the highest value appeared in Wuhan section of the Yangtze river. The content of PAHs, LPAHs/HPAHs and individual PAH in three rivers are studied. The light PAHs were the dominate form in the Fujiang and Songhuajiang river and the heavy PAHs increased significantly in the Yangtze river. The sources of PAHs were identified by characteristic ratio that PAHs were generally from combustion in Fujiang and Songhuajiang river, and the source in the Yangtze river was complicated.

Key words:  PAHs, river water, pollution source, typical river
