stockpiled in the laboratory before analysis. The second objective was to recommend methods and storage that diminish possible chemical transformations in solution samples. Depending on the sampling design, solution samples collected in the forest were to various extents subject to ambient air temperature fluctuations during the day and high light exposure. In the summertime the temperature in samples could get unfavorably high when
samples were not protected properly. Our storage experiments showed changes in chemical composition in samples stored for longer periods both in the laboratory and the forest; however, the results suggested that it is most important to reduce the duration of sampling period (i.e. weekly samples instead of bi-weekly or monthly sampling) in the forest.
