Abstract
In this paper we present the foliar response reaction induced by atmospheric pollutants on the Aesculus hippocastanum L. and Tilia tomentosa L. species situated around Iaşi city`s air quality monitoring stations. Pollutants monitored by the five stations are represented by gaseous (sulfur dioxide, carbon dioxide, nitrogen dioxide, ozone) and solid pollutants (dust prone to sedimentation). Our investigations focused on morphological observations and tracked the dynamic of physiological and biochemical changes induced on leaves as compared with the unpolluted ones. We emphasized that the large amount of dry leaves is not always related to necrotic leaf surface. It was found that the amount of chlorophyll a and b and the intensity of photosynthesis aren`t always correlated, as already known from literature.
