Description
Technical Field
The invention relates to the technical field of air pollution detection, in particular to a novel health risk evaluation method for an air pollution binary mixture.
Background
The environmental pollution problem is never only the pollution problem of a single chemical. The various pollutants in the real environment are often present in a mixed form and produce combined toxic effects when exposed to the human population. Because the combined action of mixed pollution produces complex and changeable health effects, the calculation and evaluation of combined toxicity and health risks thereof are always the difficulties and focuses of scientific attention. As early as 2013, the National Institute of Environmental Health Sciences (NIEHS) pointed out that elucidating the Health effects of Environmental mixtures should be one of the priority studies in the future. Atmospheric fine particulate matter (fineparticulate materials, PM2.5) is a natural mixed system. However, not only does the impact of PM2.5 exposure on human health vary significantly from region to region due to the different pollution compositions in a particular region, but atmospheric pollutants from different sources in the same region also exhibit widely different health impacts. Kan et al in 2005 indicated that the health impact of air pollution in china is different from that in developed countries. Laden et al found that when PM2.5 from motor vehicles and coal sources is increased by 10 μ g/m3, the daily mortality of crowds is increased by 3.4% and 1.1%, respectively, and the health hazard of fine particles from motor vehicles is higher. Therefore, accurate prediction of the combined toxicity of the air pollution mixture is a prerequisite for scientific assessment of the accumulated health risk.
In the prior art, the detection of multi-atmosphere pollution in a monitoring area is mostly carried out between ground passing devices, the three-dimensional airspace area cannot be measured, and the ground measuring points are fixed measuring points with representative lines, so that illegal discharge loopholes are provided for bad manufacturers, and air quality health assessment is caused to have loopholes.
