Abstract

A GIS-based (geographical information system) quantitative hazard- and risk-assessment methodology was implemented within an environmental risk management approach to quantify metal emissions and environmental risk from point and diffuse pollution sources in an abandoned base-metal sulfidic-ore-mining area of the Toka Creek watershed, in Gyöngyö soroszi, NE Hungary. The highest risk/threat to water and soil quality in the area arises from erosion due to rainfall/run-off of the nonvegetated/bare mine-waste dump surfaces which contain toxic metal sulfides. The water-soluble and eroded solid-phase-related toxic element (As, Cd, Pb and Zn) emissions delivered by the run-off were estimated by GIS-based flow accumulation and erosion modelling. The GIS-based approach was integrated into a three-tiered iterative risk-assessment methodology, including: (1 ) qualitative risk assessment; (2) emission-based quantitative hazard; and (3) site-specific quantitative risk assessment tiers. This paper deals with the emission-based quantitative hazard and site-specific quantitative risk-assessment tier. Combined chemical- and phytoremediation (CCP) remediation technology was planned to mitigate toxic metal emissions. The targeted toxic metal (As, Cd, Pb and Zn) emissions to be mitigated were related to the water and the eroded-solid phase, and they were predicted with the aid of GIS models. The predicted emission values were based on the assumption that the water quality of the Toka Creek complies with the Environmental Quality Criteria stipulated for the surface-water ecosystem, and that the erosion of the mine-waste dump area is restricted to the erosion level of the local forest area
