Problems solved by technology

[0008] In the existing non-tailpipe emission research literature, Fan Shoubin studied the emission characteristics based on the emission factor values ​​reported in the literature and the vehicle composition of typical road sections [Fan Shoubin. Study on the characteristics of vehicle non-tailpipe particulate matter emissions[J].Environmental Science and Technology, 2011,34(5):124-127.], in terms of non-tailpipe emission inventory, almost all current studies are based on statistics of motor vehicle ownership and average mileage of single vehicle, which cannot accurately reflect the non-exhaustive sources of road movement. Spatiotemporal variability of tailpipe particulate emissions, lacking in spatiotemporal resolution or regional representation

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a method for establishing a particulate matter emission list of "non-tailpipe" road mobile sources. Background technique [0002] As one of the main means of transportation in modern society, automobiles are widely used in various fields of people's production and life. The total number of automobiles is increasing day by day, which brings more and more problems. In addition to automobile exhaust and noise seriously affecting people's living environment, the environmental impact of "non-tailpipe" particulate matter emissions has also attracted more and more attention. [0003] "Non-tailpipe" emissions mainly include brake wear, tire wear, road wear and vehicle dust. "Non-tailpipe" emissions are an important source of trace metals in the urban environment and an important source of particulate matter in the atmospheric environment. [0004] For convenience, the c...
