Investigations into SO 2 absorption by spruce barks using artificial fumigation have proved that continued immissions of SO 2 alter the properties of bark making them capable of accumulating SO 2 up to amounts never attainable by barks grown in clean air. This can be recognized by the time lapse considering SO 2 absorption and by altered ion exchange as well as buffer capacity. With respect to the availability of the bark extracts for mapping SO 2 immissions in the field it is concluded that both conductance and sulphate content of bark extracts represent an integration covering a considerable preceding period being modified by the actual immissions.
