Level of Contamination Assessment of Potentially Toxic Elements in the Urban Soils of Volos City (Central Greece)

A three-year study, designed to record the level of potentially toxic elements within urban complex in city Volos, Greece, was carried out between 2018 and 2020. For needs aforementioned 62 surface (0–15 cm) soil samples were collected each year (i.e., 186 total) from an area 3.65 km2, average value pseudo-total metal concentration measured. Soil pollution indices, such as contamination factor (CF) geo-accumulation index (Igeo), estimated regarding metals interest. The respective thematic maps constructed, spatial variability degree displayed. Higher values CF Igeo obtained near heavy traffic roads beside railway station, bus stations, commercial port. based on along with database that constructed using appropriate mathematical tools geostatistical analysis, may be a useful tool for monitoring, prediction, continuous verification soils Volos city.
