Abstract

Chlorophyll a fluorescence induction kinetic parameters of dark-adapted leaves of Sonchus spp. and Taraxacum spp. were found to be useful biomonitors of urban pollution arising from atmospheric and soil sources. A stress index factor (SIF) was generated using canonical variate analysis based on the variation in values of Fo, Fm and t|/2- Using SIF as an index of pollution levels, a contour isostress map of Thessaloniki was constructed. The concentrations of Pb, Zn and Cu in the soil and the plant tissue were higher in areas of higher traffic density and air pollution. Multiple regression analysis showed that individual or combinations of the metal
