Abstract:
According to the actual situation of soil, the selection of appropriate source resolution method is of great significance for the identification of the source of heavy metal pollutants in the soil and targeted treatment. This review summarized the domestic research progress of field soil heavy metal pollution sources in recently 10 years, according to different land use types and the commonly used sources of pollution of heavy metals analysis method to carry on the summary, in this paper various source analysis method on the basis of the advantages and limitations, mainly on principal component analysis (PCA), the positive definite matrix factorization method (PMF), absolute factor score-multiple linear regression (APCS-MLR) provision, single and multiple parameter characteristics of the application of the isotope tracer method were compared. The joint application of multiple source analysis methods and multi-parameter isotope tracer method is the future development trend of soil heavy metal pollution source analysis research.
