Abstract
In this study, the accumulation sensitivities of trace elements in six types of air pollution
biomonitors (lichens, tree barks and a moss) are compared. Three analytical methods were used: 14 MeV neutron activation analysis,
thermal neutron activation analysis method and X-ray
fluorescence analysis. Studies of the local concentration variations versus the sizes of lichen and
of their altitude of collection from grounds, revealed that a standardisation of the procedures for
collecting samples was necessary.
