Pollution evaluation of child-care centers and playgrounds of Zagreb: geochemical mapping and GIS modelling

Guidance values for heavy metals in soils for child-care centers and playgrounds have not been developed in Croatia. Evaluation of heavy metal pollution for 150 child-care centers and 50 playgrounds in Zagreb allowed derivation of guidance values for heavy metal based on oral intake of soil by children. Modelling was performed on heavy metal concentrations of surface soil (0-5 cm), household dust and background concetrations of deeper horizons (30-40 cm), and soil heavy metal data for urban Zagreb analysed in the early 1990s.
