Evaluation of Chronic Obstructive Pulmonary Disease Attributed to Atmospheric O3, NO2 and SO2 in Tehran City, from 2005 to 2014
Air pollution in Tehran is considered as one of the most important factors threatening human health. High concentrations of pollutants have adverse effects on citizens and the environment. We calculated the relation between COPD and criteria air pollutants in Tehran, one of the most polluted cities in the world during 2005 to 2014.
Hourly data of pollutants include SO2, O3 and NO2 were taken from the Tehran environmental protection agency and Air Quality Control Company. The AirQ2,2,3 model that proposed by the WHO, is used to health impact assessment of pollutants in terms of hospital admission due to Chronic Obstructive Pulmonary Disease.
Results indicated that the total cumulative number of cases due to hospital admission due to COPD in Tehran city from 2005 to 2014 for SO2, O3 and NO2 was 1806, 2941 and 2454 cases, respectively. The finding of this study showed that total mean of SO2, O3 and NO2 was higher than the standard concentration. By comparison with guideline and standards, annual concentration for SO2, O3 and NO2 was exceeded on standard level in during the study period.
This study demonstrated that a high percentage of hospital admission due to Chronic Obstructive Pulmonary Disease resulting from these pollutants could be due to the high average concentration in the air of Tehran during 2005 to 2014. So, authorities must apply the efforts and necessities actions based on comprehensive scientific researches to control air pollutants and abate their negative effects on human health
Effect of Air Pollution on the Emergency Admissions of Cardiovascular and Respiratory Patients, Using the Air Quality Model: A Study in Tehran, 2005-2014
Background: Air pollution is one of the most important factors threatening the health of
citizens. It increases the prevalence of cardiovascular and respiratory diseases as well as
emergency admissions to hospitals in the polluted metropolitan cities. The present study was
conducted using Air Quality (AirQ) model and aimed to investigate the effects of air pollution
on the number of emergency cardiovascular and respiratory patients admissions in Tehran
hospitals during 2005-2014.
Materials and Methods: This was cross-sectional study. First, the needed hourly information
was received from the Bureau of Air Quality Control, and the Environmental Protection
Agency of Tehran City. Then, the information was validated according to WHO criteria, and
the statistical indicators and the stages required to quantify the harmful effects of air pollutants
were calculated by using appropriate application.
Results: According to the results, the number of cases admitted to the emergency ward of
hospitals due to heart diseases (by exposure to particulate matter) during the years 2005 to
2014 were respectively 1797, 1280, 1766, 1980, 2132, 2703, 2389, 2594, 2158, and 2291
cases, totaling 20990 persons, and for respiratory diseases (due to exposure to particulate
matter) during the same years were respectively 4643, 3301, 4650, 5117, 5511, 6999, 6180,
6452, 5577, and 5922 cases, totaling 54352 people. Also, the number of cases admitted to
the emergency wards of hospitals due to chronic obstructive pulmonary disease caused by
exposure to emissions of pollutants such as sulfur dioxide, nitrogen dioxide, and ozone were
respectively, 1806, 2454, and 2941 cases.
Conclusion: Air pollution in Tehran increases the load of emergency visits to hospitals and
increases the risk of respiratory and heart diseases. Therefore, measures to reduce and control
air pollution and to prepare, equip, and mobilize hospitals, particularly emergency wards, are
among important priorities that should be pursued seriously by the authorities
