Assessment of the Effects of Life Cycle of Power Plants on the Pressure of Citizens (Case Study: Tabriz Thermal Power Plant)

The life cycle of thermal power plants is along with greenhouse gas emissions. Therefore, if the pollutants of the power plant and the role of each of these substances are not identified in the contamination of the air, it can seriously expose the physical and mental health of citizens to risks. Accordingly, the purpose of this study is to measure the contaminated materials of Tabriz thermal power plant and their effects on the air pollution of Tabriz metropolitan area as well as its effects over the psychological pressure of citizens. To measure the pollutants of the power plant the GWP100 method is used, and DASS21 and Marquam's Questionnaire are used to measure the spiritual and psychological pressures of citizens. The results showed that the most pollutant emissions from the Tabriz power plant are CO2 and NOx. The volume of these materials in cold seasons is more than warm seasons. Also, the findings of the effects of air pollution on spiritual and psychological pressures of citizens showed that the air pollution caused by the activity of the power plant greatly increases the spiritual and psychological pressure of the citizens. The feeling of change in everyday behavioral patterns, feelings of despair and despair in life, stress and psychological stress have been the highest correlation of 0.556, 0.511 and 0.503, respectively, which were in winter. The results of regression test showed that 29.32% of variance changes were due to air pollution caused by the life cycle of Tabriz power plant. In addition, the findings of this study showed that in the areas close to Tabriz thermal power plant, the amount of pollution and the amount of stress is higher than the distant regions. Due to the direction of winds that transfer the plant's greenhouse gases to the city of Tabriz, it is better to replace the power plant site within a short-term plan and replace the fuel of the power plant.
