Abstract

The invention relates to an atmospheric particulate matter health risk coming source analysis method, and the method comprises the following steps: collecting atmospheric particulates to obtain a particulate matter sample; analyzing and determining chemical components in the particulate matter sample; identifying the source class of the particulate matter sample by adopting a factor analysis modeland calculating the contribution of the corresponding source class; identifying the coming direction of a pollution source in the particulate matter sample and calculating the coming direction contribution of the corresponding pollution source; and evaluating the health risk of the preset pollution source by adopting the risk evaluation model. According to the atmospheric particulate matter health risk arrival source analysis method provided by the invention, the risk influence of the preset arrival atmospheric particulate matters on human health can be quantitatively analyzed, so the healthrisk of specific arrival particulate matters is better judged, targeted treatment is realized, and a source control strategy is optimized.

Description

technical field [0001] The invention belongs to the field of environmental science and technology, and in particular relates to a method for analyzing the source of health risks of atmospheric particles. Background technique [0002] The existing source analysis method of atmospheric particulate matter is to calculate the contribution of different sources to the mass concentration of atmospheric particulate matter, but there is a lack of corresponding source analysis method for the health risk of atmospheric particulate matter, so it is impossible to quantitatively analyze the impact of different sources of atmospheric particulate matter on human health risk impact. Contents of the invention [0003] In order to solve the above problems, the present invention provides a method for analyzing the health risks of atmospheric particulate matter to the source, and the method includes the steps of: [0004] Collect atmospheric particulate matter to obtain particulate matter sam...
