Embodiment Construction

[0065] The following will be combined with this manual Figure 1-2 , to clearly and completely describe the specific examples of the road sediment polycyclic aromatic hydrocarbon source apportionment method coupled with the migration and conversion process of the present invention.

[0066] Step 1. Set up sample points based on the geographical location, urban type, road area, population, urban pattern, pillar industries, and surface runoff scour path information of the research area object, and collect common polycyclic aromatic hydrocarbon pollution sources in the city, including asphalt pavement, Concrete and cement pavement wear samples; tires, fresh engine oil, waste engine oil traffic source samples; coal combustion dust, coke oven dust, biomass combustion dust, factory dust and other combustion and industrial samples.

[0067] according to figure 1 The distribution of the sample points shown is for road sediment sampling, and 30 road sediment sampling points (BJ1~BJ30)...

Abstract

The invention relates to a road sediment polycyclic aromatic hydrocarbon source analysis method coupled with a migration and transformation process. The method comprises the following main steps: 1, collecting a road sediment sample at a set sample point; 2, determining the content concentrations and detection limits of various polycyclic aromatic hydrocarbons in the sample by using a gas chromatograph-mass spectrometer (GC / MS) to establish an acceptor matrix C and an uncertainty matrix U for describing the contents of various polycyclic aromatic hydrocarbons in the sample point; 3, establishing a source component spectrum library matrix S of the polycyclic aromatic hydrocarbon source; The method provided by the invention can provide technical support for an environmental management department to formulate regional polycyclic aromatic hydrocarbon pollution control countermeasures, so that the environmental management department can quickly identify a pollution source through a completesource analysis method when facing a road polycyclic aromatic hydrocarbon pollution problem, thereby carrying out effective pollution prevention and control.

Description

technical field [0001] The invention relates to the technical field of pollution source analysis, in particular to a method for source analysis of polycyclic aromatic hydrocarbons in road sediments coupled with migration and transformation processes. Background technique [0002] With the massive development and utilization of natural resources on the earth by human beings, it has had a serious impact on water bodies, soil, atmosphere, and the environment. How to prevent and improve the production and living environment where polycyclic aromatic hydrocarbons pollution sources are resistant to human survival has been mentioned. on the agenda. At present, the analysis of pollution sources focuses on two aspects. One is to focus on judging the source types of major pollutants in the environmental medium, which is called source identification; the other is to quantitatively calculate the contribution of various pollution sources on the basis of source identification. The size i...
