| Summary: | In today's world where human life is dependent on the industry, the problems impose in the human life along with theachievement of growing in the field of industrial works. One of the challenging problems is entry of pollutants into air that has the destructive effects on human life and environment especially plants. Plants show different responses against the air pollutants. Plant responses can be vary due to climate, geography and plant species. In this study, the effects of air pollutants in the Shazand industrial area (refinery, petrochemical and thermal power) stationin Markazi province has been checked on almond. For this purpose, the leaves of almond in Haftadgholle (control area), Shazand (closest city to industrial zone) and Kazaz (adjacent industrial zone) were collected. Also, soil samples were collected from three areas to determine lead and zinc amounts in soil. Results showed that proline, sulfur, heavy metals (lead and zinc) and lipid peroxidation enhanced significantly in Kazaz and Shazand in compared with Haftadgholle, while antioxidant activity of catalase, superoxide dismutase and guaicol peroxidase didn’t significant changes in three areas. The increase of sulfur amount in leaves, lead and zinc in soil of the Kazaz and Shazand regions could be one of the reasons to prove the presence of pollutants in these areas. The increase of lipid peroxidation indicative plant damage against the air pollution. The plant defense mechanism against of stress is the increase of non-enzymatic antioxidant proline. No change in chlorophylls and protein contents reflects increased resistance to the stress. |
