Source Apportionment of Potentially Toxic Elements in Agricultural Soils of Yingtan City, Jiangxi Province, China: A Principal Component Analysis-Positive Matrix Factorization Method.

ABSTRACT: The increase in the concentration of potentially toxic elements in farmland soil attracts more and more attention. To identify the sources of potentially toxic elements in agricultural soils, 148 soil samples in Yingtan were selected as a case study, potentially toxic elements levels were analyzed, and principal component analysis (PCA) and positive matrix factorization (PMF) were employed. The results indicate that the average of Zn (89.62 mg·kg^-1 d.w.), Cu (76.30 mg·kg^-1 d.w.), Pb (35.56 mg·kg^-1 d.w.), Mo (0.66 mg·kg^-1 d.w.), and Cd (0.59 mg·kg^-1 d.w.) exceed the corresponding soil background values of Jiangxi Province. Moreover, the high spatial coefficient of variation (above 1.00) for these elements suggests a significant influenc
