Short summary

This study combines a 1-year monitoring of precipitation, ombrotrophic peatland water level and pore water concentration changes with bog discharge and DOC, iron, As and Pb stream concentrations. Exports of As and Pb are dependent on not only the amount of precipitation and discharge but also the frequency and depth of water table fluctuations by connection of additional DOC, As and Pb pools in the acrotelm during water table rise, which is most pronounced after drought.
