[Characteristics, Health Risks, and Source Analysis of Heavy Metal Pollution in Surface Soil in Shanxian County].

Soil heavy metal （HM） pollution is a prominent global environmental problem. Understanding the risk characteristics and quantitative analysis of potential sources of soil HM pollution is of great significance for accurate prevention and control, scientific management, and safe utilization of soil resources. In the surface soil of Shanxian County, the contents of eight HMs, such as As, Cd, Cr, Cu, Hg, Ni, Pb, and Zn, were collected and identified in 330 surface soil samples.

[Potential Source Identification and Ecological Risk Assessment of Heavy Metals in Surface Soil of Heze Oil Peony Planting Area Based on PMF-PCA/APCS and PERI].

To study the sources and potential risks of heavy metals in soils of characteristic agricultural product producing areas is of great significance for the scientific management and safe utilization of soil and crop resources. The contents of heavy metals As, Cd, Cr, Cu, Hg, Ni, Pb, and Zn in the 254 surface soil samples collected from the Heze oil peony planting area were determined. The content characteristics and correlation of heavy metals were analyzed using multivariate statistical methods.
