More Information
Summary:The invention provides a source analysis method used for particulate pollutants in an environment and capable of realizing self-verification. The method comprises the following steps that: 1, two types of environmental samples, namely to-be-detected environmental particulate matter samples (such as atmospheric fine particulate matters) and samples of typical emission sources, are collected separately; 2, isotope ratio characteristics delta 65Cu and delta 30Si and characteristic metal ratios of the to-be-detected particulate matter samples and the samples of typical emission sources are analyzed in a laboratory, wherein the characteristic metal ratios refer to substance concentration ratios of two relatively unique metals in different emission sources and comprise La/Ce, Zn/Cd, Ni/V and Fe/Al; and 3, the contribution degree fi of each typical emission source is quantified by means of a Bayesian model (3). The method provided by the invention can be used for qualitative and quantitative analysis of particulate
