This study confirms that CO 2 uptake of European conifers increases during needle maturation. Extensive investigations with grafts of several species show that this increase may even mask a deleterious effect of a weak SO 2 stress. In plants which are not dependent on air‐borne SO 2 for S nutrition CO 2 uptake was not favored by SO 2 . Peroxidase activity of tree foliage may be a valuable stress indication, particularly in areas with light air pollution. It is, however, not specific for air pollution and seems to be most suitable for “active” monitoring.
