Problems solved by technology
However, the current source apportionment results usually only give the contribution rate of the pollution source to the concentration of the environmental receptor point, and cannot give the contribution to the impact on human health. Therefore, human exposure and risk assessment are introduced, combined with the emission inventory model in source apportionment, to analyze the pollution source The impact on human health risks in the environment has an indispensable practical value for the public to effectively reduce air pollution health damage and for government departments to take precise countermeasures
[0004] Furthermore, the current analysis of air pollution sources is mainly focused on pollutants and locations, and has not yet been connected to individuals. There is a lack of analysis of air pollution risk sources for individuals

Embodiment Construction
[0060] The following is a detailed description of a preferred embodiment of the present invention with reference to the accompanying drawings.
[0061] The present invention is based on the PM of the tiny pollution scene 2.5 Sampling of components (including V, Cr, Mn, Co, Ni, As, Cd, etc.), analytical analysis data and individual movement monitoring data, and matching the individual track points with the microenvironment in time and space to obtain the concentration of the components at the individual's location; Then, combined with the monitoring data of individual behavior patterns, calculate the personal PM 2.5 The air pollution risk index of each component (time resolution 1h); finally, according to the individual air pollution risk index, analyze when, where, and what kind of PM the individual is exposed to 2.5 Components have the greatest health impact; meanwhile, based on emission inventory data and microenvironmental PM 2.5 Source analysis data of medium and heavy m...

The invention discloses a method for analyzing individual air pollution risk sources based on spatial location. Firstly, the PM based on the tiny pollution scene 2.5 Sampling, component assay analysis data, and individual movement monitoring data are used to match the individual track points with the microenvironment in time and space to obtain the component concentration at the individual's location; then, combined with the monitoring data of individual behavior patterns, the personal exposure to PM is calculated. 2.5 The air pollution risk index of each component; finally, according to the individual air pollution risk index, analyze when, where, and what kind of PM the individual is exposed to 2.5 The health impact of the component is the greatest; at the same time, analyze the PM 2.5 The types of sources of pollution and their contribution rates, to achieve the construction of an individual air pollution risk source analysis method with a time resolution of ≤1h. The invention is a comprehensive and accurate air pollution risk source analysis method for individuals, and has the beneficial effect of being able to provide more comprehensive data support for individuals to avoid air pollution.
Description
technical field [0001] The invention relates to an air pollution risk source analysis method for integrating risk time, risk location, pollutants, risk source analysis, etc. for individuals, and belongs to the field of environmental exposure assessment and air pollution source analysis. Background technique [0002] Air pollution has been a prominent environmental problem in my country in recent years. Air pollution is a serious hazard and its sources are complex. As a result, the types of gaseous pollutants involved are complex and the particle size distribution spectrum is wide. It is easy to present the composite pollution characteristics of multiple pollution sources superimposed, which may lead to more serious composite health effects. Therefore, it is of great significance to accurately identify the sources of air pollution and obtain the contribution rate of each pollution source category. [0003] The impact of air pollution on the health of exposed populations is n...
