abstract = {For the registration of pesticides in the European Union,
model simulations for worst-case scenarios are used to
demonstrate that leaching concentrations to groundwater do
not exceed a critical threshold. A worst-case scenario is a
combination of soil and climate properties for which
predicted leaching concentrations are higher than a certain
percentile of the spatial concentration distribution within
a region. The derivation of scenarios is complicated by
uncertainty about soil and pesticide fate parameters. As the
ranking of climate and soil property combinations according
to predicted leaching concentrations is different for
different pesticides, the worst-case scenario for one
pesticide may misrepresent the worst case for another
pesticide, which leads to 'scenario uncertainty'.Pesticide
fate parameter uncertainty led to higher concentrations in
the higher percentiles of spatial concentration
distributions, especially for distributions in smaller and
more homogeneous regions. The effect of pesticide fate
parameter uncertainty on the spatial concentration
distribution was small when compared with the uncertainty of
local concentration predictions and with the scenario
uncertainty.Uncertainty in pesticide fate parameters and
scenario uncertainty can be accounted for using higher
percentiles of spatial concentration distributions and
considering a range of pesticides for the scenario
selection.},
