  1 - The analysis of Daily trend of air pollutants in Tehran Metropolis

  In this study, used to data from six major pollutants measurable standards Tehran air containing sulfur dioxide (SO2), carbon monoxide (CO), particulate matter (PM2.5 and PM10), nitrogen dioxide (NO2) and ozone gas (O3 In a period of usually 11 years from 2002 to 2012 f More

  In this study, used to data from six major pollutants measurable standards Tehran air containing sulfur dioxide (SO2), carbon monoxide (CO), particulate matter (PM2.5 and PM10), nitrogen dioxide (NO2) and ozone gas (O3 In a period of usually 11 years from 2002 to 2012 for a total of 4018 to analyze and assess the historical distribution of pollutants in the atmosphere in Tehran. In this study different methods included descriptive statistics, linear trend component analysis of time series in particular, descriptive statistics, polynomials, and exponential regressions and Mann-Kendall nonparametric method for detection of the significance of trends have been used. Historical trend analysis data showed that the SO2 air pollution in Tehran with a share of 3, CO, with linear, NO2 and O3, with a view to contribute degree 2 is a better fit. The particulate matter 2.5 and 10 micron did not show clear and significant trend during the study period. Results of mann -Kendall showed that the variation of pollutants CO, NO2, O3 with 95 % confidence intervals was significant, but the variability of the pollutants CO and particulate matter PM10 and PM2.5 aren’t significant. Therefore according to the historical data of some air pollutants in Tehran and is expected to continue its current NO2 air pollution in Tehran has increased significantly and will continue to air pollution in Tehran with regard to the above mentioned pollutants continue. But if emissions of CO and particulate air pollutants PM2.5 and PM10 with the current trend continues, a significant decrease of pollutants is not expected, but the current trend is expected to continue the process and pollutant emissions of CO.

  2 - The effect of changes in land use and reducing urban green space on surface temperatures and the urban heat island of Tehran (Case study: Region 1)

  This study was conducted to investigate the microclimate role of extruded builders in the last decade on surface temperature rise and heat island resonance and air pollution in the Tehran area. Shemiranat station data and Aqdasia air pollution measurement data over a 12 year statistical period were used. Landsat 8 satellite images were used to reveal the role of vegetation reduction on surface temperature. The results showed that in area 1 due to non-regular and unconditional construction in recent decades, the vegetation and trees of the area were not cut or standard green space development was not followed. Two hot areas, or islands of high surface temperature heat, are forming and developing over other adjacent parts. The eastern half of Region 1, especially its southeastern part, boasts a very hot part in all seasons. In hot seasons, surface temperatures in the area can reach as high as 50 degrees Celsius. The middle section is still better off if it still manages to maintain its green space. However, due to the steady growth of builders in the last decade, the minimum (morning) temperatures, especially in cold seasons, are rising rapidly and steeply. The amounts of fine-grained particles, especially PM10 and PM2, are increasing in region 1.The intensification of the heat island has caused south-west to south-southeast winds to intensify all months of the year. And it has made the area particularly polluted in the colder months of the year. The purpose of this study was to investigate the role of changes in land use and deforestation and loss of vegetation in changes in surface temperature and heat island of Tehran metropolitan area.

  Today, the increase and development of urbanization, industrial activities and the consumption of fossil fuels have increased air pollution in large cities. One of the indicators of air pollution is nitrogen dioxide. In this paper, the trend of changes in the concentration of nitrogen dioxide related to the troposphere in the city of Kermanshah in the period 2006 to 2018 is presented. In this study, the monthly concentrations of nitrogen dioxide obtained show that the highest amount of nitrogen dioxide occurs in winter and the lowest amount occurs in summer. As the highest amount of nitrogen dioxide occurs in January and the lowest amount occurs in June, meteorological conditions can increase the severity and extent of tropospheric nitrogen dioxide pollution. The results of tropospheric nitrogen dioxide concentration with meteorological parameters showed that the correlation coefficient of Pearson nitrogen dioxide with wind and surface temperature are inversely related, respectively. Reductions an OMI sensor was used to monitor nitrogen dioxide. In this study, nitrogen dioxide using an OMI sensor in February and July 2016 showed that the amount of nitrogen dioxide was higher in February and lower in July. Manuscript profile

  Objective: This research aims to analyse key stakeholders in Tehran air pollution control project during its life cycle. Methods: Since the research is qualitative, after librarian research and gathering research literature, the actors of Tehran air pollution control project were recognized and the outputs analyzed using Delphi method. Key actors were determined after Delphi method application and analyzed using power-interest matrix during life cycle. Results: in the present study, 12 key actors identified and selected from 23 actors as follows: “Ministry of Industry, Mine and Trade”, “Environmental Protection Agency”, “Islamic Republic of Iran Broadcasting Organization”, “National Standard Organization of Iran”, “Tehran Air Quality Control Company”, “Deputy of Transport and Traffic of Tehran Municipality”, “Insurance organizations”, “Oil Ministry”, “traffic police”, “Automakers”, “Ministry of Health and Medical Education”, “Environmental Protection and Sustainable Development Organization of Tehran Municipality”. Conclusion: in the present study, key actors changed in each stage of projects life cycle while in almost all similar projects this fundamental change has been ignored in the project run time. also after reviwing formal documents, laws and strategies that have been written for solving air pollution crisis it was found that “Insurance organizations” have been ignored as a key actor in solving this crisis.

  5 - Principles of State Civil Liability for Environmental Pollution

  Today, with the expansion of international relations and relationships, the issue of environmental law has been at the forefront of international attention, and all governments and individuals are working to maintain environmental conditions in a healthy environment. One could consider one of the components of a good state or good governance as an environmental issue and, in particular, a clean air. In fact, one of the most important environmental issues is the issue of air pollution, which today is inevitable to find solutions to tackle and mitigate this phenomenon. It should be noted that the right to a healthy environment, except for human rights, including rights Is inherent in human beings. In order to deal with this phenomenon, civil liability was raised, according to which the loss factor should be compensated. One of the foundations of civil responsibility is the theory of fault that this theory is less used because of the lack of recognition of the actual cause of the damage, and to solve this problem, theories of liability are blamed and blamed on the responsibility of the majority of European countries. The remedies in this area are also restoring the state of the past, eliminating the source of losses, compensating for losses, and committing to non-contamination. In the area of civil liability caused by pollution, there are complexities such as the multiplicity of features, gradual and hidden losses, the difficulty of assessing damages, and the ability to prove the relationship between the causation. Therefore, it is necessary in this regard, It will be possible to first develop preventive measures against people, as well as by adopting precise and comprehensive laws and regulations in this area, these issues can be reduced.
