| description | Research made in the atmospheric deposition
monitoring program have shown a great
variability in the mineral ion content of
rainwater samples, especially in samples took
under the stand canopy. To prove that the litter
in the samplers can influence the results of
analysis of samples, it was organised a
bifactorial experiment (contact time and the
nature of litter) with each factor repeated 3-6
times. In distillate water were placed different
amounts of litter, with the contact time of 3 to
30 days, after which were analysed with
conventional methods. The obtained results led
to following conclusions: (1) in small quantities
of litter, the influence of litter on results of
analysis was insignificant, (2) in high
concentration of litter (1-2 g/l) the errors were of
20-30 % in K and N-NH
4 concentrations, while
in the concentrations other ions the error was 5-
20 % from the annual mean concentration and
(3) in very large quantities of litter (>5 g/l) the
sample concentration can increase with values
of 20-80 % from the annual mean concentration.
The largest values can be encountered in K and
N-NH
4 and the minimum values in Na |
