SUMMARY: The ICP Forests and EU Regulation aim to conduct intensive
and continous monitoring on forests ecosystem as a means of evaluating the
damage caused atmosferic pollution and other factors influencing forest con-
dition.There is no doubt that phosphorus and nitrogen are among the most important
elements for the biosphere and its biochemical cycles. Therefore, to
get the most correct information about the concentration of different types of
these elements is invaluable for understanding the control and creating biochemical
cycles.In this work the implementation and validation of new colorimetric
method on automatic analyser for determination of phosphorus and
ammonia has been investigeted. The investigation was performed on samples
precipitated water in the forest ecosystem.Until now standard methods, spectrophotometry
has been used for determination of phosphorus and
ammonia.In the validation procedure following criteria have been investigated:
graphical analyses of measured results, accuarcy, linearity in the working
range, the limit of detection, the limit of quantification and the repeatability.
The results showed that the method for determination of phosphorus and ammonia
on automatic analyser is linear in the range of investigation (Table 1),
while the t-test has showed that differences between these two methods are not
significant being 99,99 %. From the control charts it is obvious that the repea
