1st International Electronic Conference on Geosciences
A: Environmental Geochemistry: Geogenic versus Anthropogenic Source
Prof. Dr. Maurizio Barbieri, Department of Earth Sciences, Sapienza University of Rome, P.le Aldo Moro, 5 - 00185 Roma, Italy
The environmental pollution of soils by metals is a serious problem for biota, and it directly affects human health because metals have excellent ecological transference potential. 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. Papers for this Section on Environmental Geochemistry include, without being limited to, the following themes:
- Trace elements;
- Advances in analytical techniques;
- Environmental pollution and health;
- Geochemical baseline data for urban and rural areas.
