Originofthisresearch

has gonewith new idea to findmechanismformapvisualizationofquantitativeassessmentofhealthrisksfromcontaminationofgeologicalenvironment in the Slovak Republic

by

combininginternationalprinciples and methodologyofhealth risk assessmentwithmethodologicalproceduresused in environmentalgeochemistry

thatwouldbe

easy to understand and usefull in decisionmakeprocess

Objectiveoftheworkwasbased on this idea and includes:

Quantitativeestimationofhealth risk to residentsliving in the Slovak Republicofexposure to contaminatedgroundwater (adultpopulation) and soils (adult and childpopulation)

Identificationofpotential risk areaswithinthe country based on mapvisualization.

Backgroundofthework

  • Identification and characterizationof:

  • distributionofchemicals in groundwater and soils,

  • contaminationofgeologicalenvironment and sourcesofcontamination,

  • Withinenvironmental-geochemicalmappingprogramme in the Slovak Republicat:

  • nationallevel – GeochemicalAtlasesofthe Slovak Republicatthescale 1:1 000 000,

  • regionallevel – environmental-geochemicalmapsofselectedregionsatthescale 1:50 000.

Backgroundofthework

Sourcesofgroundwater and soilcontamination in the Slovak Republic:

Main geogenic (natural) sources

  • specific rock typesand associatedmineralizationoccurrencesandoredeposits

  • (e.g. hydrothermalveinmineralizationassociatedwithgranitoidsand metamorphicrocks, low-sulphidemineralizationassociatedwithNeogenevolcanics, Paleozoicsediment-hostedmineralizations)

Increasedgroundwater and soilcontentsofpotentiallytoxicelements: As, Pb, Zn, Cu, Hg, Sb

Main anthropogenicsources

  • Miningactivities, Metallurgy, Agriculture, Wasteindustry, Otherindustrialactivities(chemicalindustry, refineriesetc.), Transport etc.

Increasedgroundwater and soilcontentsofvariouschemicalelements / components: As, Cd, Hg, Pb, Ni, Fe, Mn, Al, Zn, Cu, Cr, NO3-, SO42-, NH4+etc.

Geogenic-anthropogenicsources (e.g. historicalminingareas)

Health risk estimate – US EPA methodology

Dataevaluation

Meanvaluesfor Slovak municipalitiesforfollowingcontaminantswithdefined toxicity datawereincluded in calculationofhealth risk estimates:

Groundwater – As, Ba, Cd, Cu, F, Hg, Mn, NO3, Pb, Sb, Se, Zn

Soils - As, B, Ba, Be, Cd, Cu, F, Hg, Mn, Mo, Ni, Pb, Sb, Se, Zn

Exposureassessment

Toxicity assessment (IRIS database)

Chroniceffects: principleof REFERENCE DOSE (RfD) wasapplied („existenceof „safe“ dose)
