Notes:
A three tiered, iterative Environmental Risk Assessment methodology, including preliminaryQualitative Risk Assessment, Quantitative Hazard Assessment and Site Specific QuantitativeRisk Assessment, was established to assess the environmental risk of point and diffuse pollutionof mining origin at catchment scale [1]. The model site was an abandoned Pb and Zn sulphideore mine in Gyöngyösoroszi, Toka-valley, NE Hungary [2]. The Integrated Risk Model considersthe sources identified by the GIS-based (Geographical Information System) pollution map, thetransport routes shown by the GIS-based flow accumulation model and the receptors of differentland uses in the catchment. The site-specific quantitative risk was characterised by the Soil TestingTriad [3]. The three elements of the Triad are: physico-chemical analyses of the soil and the contaminants,the biological characterisation and ecotoxicity testing of the contaminated soil, measuringthe response of single species in laboratory bioassays, the natural response of the soil microfloraand plants or the dynamic response of the whole soil in microcosms. The Triad approach stronglysupports the characterisation of the site specific risk as well as the selection and planning of thesuitable remediation option
