METHODOLOGICAL ASPECTS OF PRECIPITATION SAMPLING FOR HEAVY METALS CONTENT INVESTIGATION

The aim of the described experiment was testing of two methods used for collecting precipitation samples at the forest (throughfall and stemflow) for heavy metals analyses. Comparison of data obtained using two methods – samples collectors made of glass and acidification of the collected samples and polyethylene collectors without acidification – has shown that the results are much smaller when standard samples were analyzed (standard samples – collected for main ions analyses). It is particularly important in case of cadmium, lead and zinc. This experiment has shown importance of proper measurement method taking into account the aim of the research, starting with samples collecting. Precipitation samples for heavy metals analyses should be collected by the collectors made of glass and after that should be acidified in order to avoid loss of the components that are subject of the investigations.
