Tracing the source of nitrate in a forested stream showing elevated concentrations during storm events
Abstract Δ 17 µ M, from 28.7 to 134.1 µ M, and from 46.6 to 114.5 µ M, during the storm events I, II, and III, respectively. On the other hand, the isotopic compositions (δ 15 δ 18 Δ 17 + - + - + - δ 15 + - + - + - δ 18 + + + + + + Δ 17 ± ± ± µ M during the storm events I, II, and III, respectively, irrespective of the significant variations in the total nitrate concentration. We concluded that the storm events have fews impacts on the concentration of unprocessed atmospheric nitrate in the stream, and thus the annual export flux of unprocessed atmospheric nitrate relative to the annual deposition flux can be a robust index to evaluate nitrogen saturation in forested catchments, irrespective to the variation in the number of storm events and/or the variation in the elapsed time from storm events to sampling.
