Data for: Phytomonitoring study on intra urban variations of leaves parameters of some evergreen and deciduous trees

These data explores the hypothesis that the action of stressors changes the state of mineral content at different stages of leaves development in urban environment:
• unfavourable site (US) - high pollution exposure, street and busy roundabout near Timisoara’s urban centre, heavy vehicular load.
• favourable site (FS) - low pollution exposure, the site is not immediately exposed to pollution sources, park.
The method is based on quantifying gravimetric (leaf dry weight - LDW, oganic weight in leaves - LO, ash weight in leaves - LA) and physiological (leaf mineral content - LMC, leaf organic content - LOC, leaf organic content / leaf mineral content ratio - LOC/LMC, leaf mineral deposition in tissues - LTDM) parameters.
Acer platanoides L., Acer pseudoplatanus L., Tilia platyphyllos Scop., Tilia tomentosa Moench., Aesculus hippocastanum L., Aesculus x carnea Hayne, Taxus baccata L., Picea abies (L.) H. Karst, were chosen for this study.
