Arsenic contamination of Arsenic contamination of Ogosta river: Linking Linking biogeochemical processes in biogeochemical processes in floodplain floodplain soils with river system dynamics
This research project has three general objectives, which are addressed in work packages WP1–WP3:
- Investigate the magnitude and spatial distribution of As contamination in the floodplains of
Ogosta river (Bulgaria) using an integrated approach based on topography, hydrology, and
- Improve our process understanding of As speciation and mobility in highly‐contaminated,
mining affected river floodplains during alternating periods of high/low flow and
flooding/drainage, respectively (WP2).
- Explore novel approaches for integrating process‐oriented, molecular‐scale knowledge (WP2)
and river‐system scale information (WP1) to better understand As dynamics, As fluxes, and
impacts on water quality at the river‐system scale (WP3).
