Embodiment 1

[0027] 1. Collect a sample of particulate matter.

[0028] In a certain place, an automatic sampler was used to collect air for 100 consecutive days, and a total of about 100 samples were collected and brought back to the laboratory.

[0029] 2. Determining the content of inorganic components and organic components in particulate matter samples.

[0030] The organic components (such as hopanes, zanes, alkanes, polycyclic aromatic hydrocarbons, levoglucosan, cholesterol, etc.) and inorganic components (such as elements Na, Mg, Al, Si, K, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Cd, Zn, Hg, Pb, etc.; ion Cl - , NO 3 - , SO 4 2- , NH 4 + Etc.; elemental carbon EC, etc.) to detect the content.

[0031] The content of organic components was measured by GC-MS (gas chromatography-mass spectrometry), and the content of metal elements was measured by ICP-MS (inductively coupled plasma mass spectrometry) or ICP-AES (inductively coupled plasma atomic emission spectrometry) or XRF ( X-ray ...

Abstract

The present invention provides a refined source apportionment method based on particulate inorganic components and organic markers, including: collecting particulate samples; measuring the content of inorganic components and organic components in the particulate samples; according to the obtained inorganic component content data, using The factor analysis model conducts source analysis on particulate matter receptors to obtain the source spectrum matrix and source contribution matrix; calculates the correlation coefficient R1 between the content of organic components and the source contribution matrix, and screens organic components according to the correlation coefficient Based on the identification and content data of inorganic components, the factor analysis model was used to carry out refined source apportionment on particulate matter receptors, and the source spectrum matrix and source contribution matrix were obtained. This source apportionment method utilizes the relationship between organic and inorganic components in particulate matter, as well as the relationship with the analytical contribution of inorganic components, to identify organic markers, and conduct fine analysis of the combination of conventional components and organic markers to meet the requirements of atmospheric particulate matter pollution management. Refinement requirements for source analysis.

Description

technical field [0001] The invention belongs to the technical field of environmental monitoring, and in particular relates to a refined source apportionment method based on particulate matter inorganic components and organic markers. Background technique [0002] In recent years, my country's urbanization and industrialization process has been rapid, energy consumption has shown a trend of continuous increase, and the number of motor vehicles has increased rapidly, making the problem of urban air pollution increasingly serious. The prevention and control of particulate matter pollution is an important part of my country's environmental management. The sources of atmospheric particulate matter are complex, and the use of source apportionment results to guide the prevention and control of particulate matter pollution can improve the scientific nature of air pollution management. Atmospheric particulate matter source analysis refers to the technical method of qualitatively or q...
