Selected soil types as pollution barriers in Slovak and Croatian karst areas.

Carbonate rock aquifers are composed of water-soluble rocks where fractures can be widespread by karsting to sinkholes, caves or tunnels causing water that water and any accompaying pollutants move very rapidly. Therefore, groundwater is very suscesible to pollution in karst areas. Even some heavy metals can migrate to considerable distances through karst channels despite the buffering capacity of surrounding carbonates. soils are often the only cover of the carbonates and in that case the thicknes, the permaebility and sorption properties control the migration velocity of contaminants.
