基于主成分分析-多元线性回归的松花江水体中多环芳烃源解析

The Research of Polycyclic Aromatic Hydrocarbons in the River Based on the Principal Component-Multivariate Linear Regression Analysis

对松花江全流域14个监测断面的16种美国环保局优先控制的多环芳烃(PAHs)的主要来源及其贡献率应用主成分因子分析-多元线性回归模型(PCA-MLR)进行了来源解析。结果表明:松花江全流域为化石和石油燃料的复合PAHs污染,水体环境中PAHs首要污染源为化石燃料燃烧和交通污染,合计贡献率为63.1%,第二大污染源为工业和民用燃煤污染,合计贡献率为36.9%,沿江的石化、石油基地、大型焦化厂、电厂都是PAHs的主要来源。

Pricipal Principal Component-Multivariate Linear Regression Analysis （PCA-MLR）was applied to analyze the distribution and sources of polycyclic aromatic hydrocarbons（PAHs） in the surface water from songhua river. Fourteen samples of the Level period were collected from songhua river. Diagnostic ratio analysis illustrated that the songhua river basin as fossil fuel and oil compound pollution of PAHs. The primary sources of PAHs in water songhua river is the burning of fossil fuels and traffic pollution, and both total contribution rate is 63. 1%. The second major pollution sources is the industrial and civil coal pollution, and the contribution rate is 36.9%. Petrochemical, oil base along the river, large coking plant, power plants are the main source of PAHs
