Spatial Distribution and Evaluation of Arsenic and Zinc Content in the Soil of a Karst Landscape

Karst features such as polje are highly vulnerable to natural and anthropogenic pollution. The main objectives of this study were investigate the soil quality in Ioannina (north-west Greece) concerning arsenic (As) zinc (Zn), delineate their origin well compare As Zn content with criteria recorded literature. For purpose, geomorphological settings, land use, physicochemical properties mapped evaluated, including texture concentrations aqua-regia extractable Zn. concentration elements was spatially correlated use geology area, while screening values applied assess suitability. results reveal that 72% total area has a very gentle slope. This relief favors urban agricultural activity. Thus, used cover 92% area. spatial distribution for is located on slopes strongly geological parent materials human-induced contamination sources. Arsenic can be considered enriched studied. median topsoil contents (in mg kg?1) (agricultural 16.0; 17.8) 92.0; 95.0) higher compared corresponding European topsoils. Land evaluation suitability given from literature discussed. proposed work may helpful project planning protection environment.
