Abstract: Three months old seedlings of three woody species of high commercial value typical from Campeche, México [Haematoxylum Campechianum L (Wood blood tree), Tabebuia Rosea (Pink flower tree) and Swietenia Macrophylla (Mahogany)] were fumigated during 6 weeks at three different concentrations of simulated tropospheric ozone (at 50, 110 and 250 ppb) using charcoal filtered air within an open-top chamber from june to july in 2009. Visible damages and changes on phtosynthetic pigments levels were identified and nutrients concentrations (Ca2+, Mn2+, Mg2+ and K+) were determined. All studied species ( Wood blood tree, Pink flower tree and Mahogany) showed sensitiveness to ozone exposure levels, showing decreases in photosynthetic pigments levels as well as changes in nutrients contents. Mahogany and Wood blood tree were the most sensitive species to tropospheric ozone showing greater visible damages .
