Study of number of total mortality, cardiovascular and Respiratory mortality attributed to air pollutants of Tehran in 2005-2014

Abstract

<p>Over the last few decades, the evidence on the adverse effects on the health of air pollution has been raised. Mortality is the most important health effect of ambient air pollution. We studied the relation between mortality and criteria pollutant air in Tehran, one of the highly industrialized, densely populated area and most polluted cities of the reign, during 2005-2014. For this purpose, we applied the approach proposed by the World Health Organization using the AirQ 2.2.3 model. Hourly concentrations of pollutants were taken from the Tehran environmental protection agency and Air Quality Control Company. In this model, the attributable proportion of health outcome, the annual number of excess cases of mortality for all causes were estimated. According to results, the number of total mortality caused by exposure to O3, NO2, SO2, PM10, PM2.5 in the past decade was 8042, 15141, 8136, 17776 and 20015 cases, respectively. The number of cumulative total mortality was 53110 cases in ten years. Furthermore, the number of cumulative cardiovascular and respiratory mortality 33887 and 8168 cases was estimated in last decade. A large number of residents of Tehran have died as a result of exposure to air pollutants; therefore for control and management of air pollution, appropriate actions on health and the environment should be performed.</p>

Synoptic analysis of the most durable pollution and clean waves during 2009–2019 in Tehran City (capital of Iran)

“…Pollution is also the most important environmental risk factor in emergence and progression of some diseases including lung cancer, asthma, Alzheimer's and Parkinson's diseases, as well as psychological complications, and devastating effects on fetus and many others (Ghorani-Azam et al 2016;Liu et al 2016;Magari et al 2001). Kermani et al (2018) found that the total number of deaths was more than 53,000 people as a result of air pollution during 2005-2014 in Tehran City of which more than 42,000 deaths were related to cardiovascular and respiratory diseases. During this period, air quality index (AQI) rate was increased by 11.8% where PM 2.5 and PM 10 pollutants played the greatest role in weakening air quality in Tehran City and its resulting hazards (Saniei et al 2016).…”
