Soil pollution: Anthropogenic versus geogenic contributions over large areas of the Lazio region

摘要

During the last three decades, the scientific community, politicians and decision makers have focussed on the behaviours of trace elements in soil, its accumulation and toxicity, the bioavailability and risk of metals, and soil remediation technologies. Trace metals (or metalloids), such as As, Pb, Cr, Cd, and Ni, cause more environmental contamination than organic chemicals. Therefore, it becomes increasingly important to distinguish between the geogenic and anthropogenic sources of these trace metals, and to understand that the background values change depending on the area and the scale of the area investigated.
