Accumulation of waste tire rubbers is one of the most important global environmental concerns. Waste tire rubbers comprise more than 12% of all solid wastes but due to their shape, size, and physicochemical composition, these wastes are very resistance against microbial degradation and recycling. Storage of waste tire rubbers in large quantities may result in serious dangerous such as fire hazard. Waste tire fire causes several environmental problems for the air, water, and soil. Plants are the first ring of the ecosystem that are exposed to gases emitted from burning tires. Therefore, changes induced by these gases in the plants can be used for monitoring their effect on human community. The aim of this study was to investigate the influence of pollution resulted from burning waste tire rubbers on growth parameters and antioxidative response of olive trees under various zinc nutrition treatments. Olive trees were grown at two individual environmental-controlled growth units at greenhouse. Trees at one growth unit were exposed to the air pollution and trees at the other unit were unexposed. Concentration of CO, NO x , H 2 S, SO 2 , CH 4 , NO, CO 2 , NO 2 and the temperature of the furnace-exhausted gases and air was measured. In addition, concentration of Zn and Fe in the emissions was measured. Leaf activity of APX, GPX, and CAT and leaf concentration of MDA, Zn and Fe, chlorophyll (a, b, and total), carotenoid, and some growth attributes were also measured at both active and inactive periods of air pollution. Microscopic characteristics of the leaf surface were also determined. Due to high concentration of Fe and Zn in gases emitted from burning tire and their effect on plant growth and antioxidative capacity, interpretation of the results was complex. Concentration of Fe and Zn was higher in plants exposed to air pollution compared with those unexposed to the air pollution. Interestingly, concentration of MDA in plants exposed to the air pollution was significantly lower than those unexposed to the air pollution. At both sampling stages, regardless of Zn nutrition treatments, activity of antioxidant enzymes in olive leaves was positively correlated with concentration of Fe and Zn. In addition, activity of these enzymes was associated with lower concentration of MDA, as an index of cell membrane oxidative damage. On the other hand, the presence of the CO, NO x , H 2 S, SO 2 , CH 4 , NO, CO 2 and NO 2 in the air damaged to the leaf surface and reduced the number of cells and leaf surface stomata and growth attributes. Although high concentrations of Fe and Zn in the emitted gases might be effective in improving activity of antioxidant enzymes in plant leaves, they were ineffective in inhibiting the injuries of the pollution on plant.
