USEtox Demo

Spatial USEtox Results (based on the Pangea Model)

Geospatial results are generated using the Pangea Model, which is currently not part of the USEtox scientific consensus model version. Pangea was developed at the University of Michigan. Spatial maps showing concentrations, exposure and toxicity impacts on humans and ecosystems will be included in the full USEtox web version for user-defined emission scenarios. This can inform spatialized impact reduction and mitigation efforts.

The original resolution of the terrestrial grid (based on the global HydroBASINS catchment dataset) can be refined based on a combination of different aspects. In the case of the herbicide atrazine applied directly to agricultural soil in, for example, the United States (U.S.), we have choses for illustrative purposes a combination of soil area fraction per catchment and national boundary of the continental U.S.

Please find further information about the Pangea model at http://pangea-model.org. Pangea was developed at the University of Michigan with contributions from Dr. Cedric Wannaz and Prof. Olivier Jolliet.

Main part of the refinement potential: Fraction of agricultural soil per level 8 catchment area of HydroBASINS (P_levels) over North America (using Pangea's allocation key to aggregate HydroATLAS land cover types into Pangea types).

Additional part of the refinement potential: Continental U.S. land area.

Final refinement potential based on a combination of fraction of agricultural soil per level 8 catchment area of HydroBASINS and continental U.S. land area.

Refined terrestrial grid visualized as HydroBASINS level 4,6,8,10 catchments (P_levels), showing that resolution is higher over regions with high refinement potential.

Refined atmospheric grid based on similar refinement potential but without geo-spatial constraints defined by the hydrology.
