Direct and Indirect effects of Air Pollution on Forest Ecosystems: the Attempt of a Resume of Scientific Investigations Carried out in Nortrhine-Westphalia/FRG during the last Decade

Since the beginning of the 80's, a wide-spread damage to Norway spruce has occurred, mainly characterized by the light-induced decay of chlorophyll in magnesium-deficient needles.
