Title:
METHOD FOR IDENTIFYING GENERATION SOURCES OF FINE PARTICULATES IN ATMOSPHERE
Document Type and Number:
WIPO Patent Application WO/2020/217543
Kind Code:
A1
Abstract:
This method for identifying generation sources of fine particulates in the atmosphere includes: a step for determining the amounts of polycyclic aromatic hydrocarbons and nitro polycyclic aromatic hydrocarbons contained in fine particulates in the atmosphere; and a step for identifying, using a logical formula derived in advance, the proportion of combustion generation sources in the atmosphere by using the amounts of the polycyclic aromatic hydrocarbons and the nitro polycyclic aromatic hydrocarbons contained in fine particulates derived from different combustion generation sources quantified in advance and the amounts of polycyclic aromatic hydrocarbons and nitro polycyclic aromatic hydrocarbons contained in the fine particulates in the atmosphere determined in the above-mentioned step. By using this method, in the atmosphere where fine particulates of different generation sources are airborne, it is possible to identify the generation sources of fine particulates in the atmosphere.
