In the process of industrialization and urbanization, human activities have caused more and more heavy metal lead to enter the surface soil, causing harm to the health of residents. Analysis of the status of lead pollution in urban surface soils in China found that lead pollution in most cities currently exceeds regional background values. The sources of heavy metals in cities mainly include transportation, industrial emissions, and human activities. At present, the methods for determining sources include three methods: multivariate statistical analysis, geographic information systems, and isotope tracing.
Key words: Pb / Urban Topsoil / Distribution
