Speciation and mobility of arsenic in the soil – water system in locality affected by historical mining

This project aims to study speciation and mobility of arsenic (As) in soil and waters affected by medieval mining dump - located in the NW part of the Jáchymov ore district (NW Bohemia). Analysis of arsenic speciation in pore water, ground water, surface water, and solids in soil and waste dump will be integrated with detailed mineralogical and geochemical observation and speciation modelling. Results of complex research will provide information on long-term As behaviour in the oxidation zone and mobility-limiting factors of As in the field conditions.
