Summary  

The study was performed in an urban area to identify the main pollution sources. Dry and living bog moss samples were exposed in parallel, and their accumulative capability as biomonitoring tools was compared. The procedures of moss exposure, preparation, and element concentration measurement performance are recommended. Chemical composition of moss material was determined using instrumental neutron activation analysis in a research reactor located in Delft, the Netherlands. The element concentration levels were lower in living moss than in dry one. Chemometric methods were suggested to identify specific element profiles attributing to factors impacting moss composition in various urban locations.
