Abstract


Polycyclic aromatic hydrocarbons ( PAHs ) , carcinogenic , teratogenic and mutagenic properties , its pollution problem has aroused great attention of scientists of the world's environment . In the Songhua River , there are more and more harmful . In this study, Jilin city as the study area , measured water period ( Fung , flat , dry ) river and the river bottom surface sediments of 16 EPA priority control the concentration of PAHs PAHs pollution degree of understanding of the section of the river . Multiple linear regression method using the ratio method and factor analysis source analysis and calculate the contribution rate of the various types of sources of PAHs in the river and the river bottom sediments . The results show that this section of the river by the river pollution situation is not serious to contaminated case of the flat water of gt ; wet period GT ; dry season, change of seasons was not significantly different impact PAHs in the section of the river in Jilin City river . PAHs in river bottom sediments and types is much higher than the river water samples , some high molecular weight PAHs in this section of the river aquatic organisms have adverse biological effects effects , also pose a security risk to human health . Ratio method is concluded that the main source of PAHs in the water of river water and sediment of petroleum origin . Factor analysis combined with multivariate linear regression to calculate the contribution rate of pollution sources to get petroleum sources are in the the PAHs sources of pollution of the water of the main source .
