Air pollution in is one of the main difficulties in Megacities that have harmful effects on humans and the environment and cause various diseases including cardiovascular disease. So, present study with aim of Study the number of cases cardiovascular mortality Attributed to CO in Tehran in during a five-years were performed.
This Study was a descriptive–analytic. At first, hourly data of pollutants were taken from the environmental protection agency Tehran and Air Quality Control Company and validated according to the WHO guidelines. Required statistical parameters calculated for health effect quantifying and finally processed data converted to input and requirements AirQ model data and health effects quantifying were performed using this model. Finally, results on deaths due to cardiovascular disease were presented in tables and graphs format.
Results showed annual average concentration of CO in Tehran in 2005-2010 are 5, 4, 4, 3 and 4 mg/m3 respectively. In addition, the number of cardiovascular mortality in 2005-2010 is 82, 73, 67, 58 and 57 respectively
According to the results, CO as well as other pollutants can adversely affect human health. Due to high levels of air pollution and its related health consequences, particularly cardiovascular disease, should take appropriate measures to reduce air pollution.

Air pollution in large cities is one of the main difficulties that have harmful effects on humans and the environment and cause various diseases including cardiovascular disease. So, present study with aim of Estimation of Cardiovascular Death, Attributed to CO Exposure in Tehran Megacity in during a five-year period (2010-2014) by using AirQ Model were performed.
This Study was a descriptive–analytic at first, hourly data of pollutants were taken from the environmental protection agency Tehran and Air Quality Control Company and validated according to the WHO guidelines. Required statistical parameters calculated for health effect quantifying and finally processed data converted to input and requirements AirQ model data and health effects quantifying were performed using this model. The final results on deaths due to cardiovascular disease were presented in tables and graphs format.
Results showed annual average concentration of CO in Tehran in 2010-2014 are 49, 31, 11,12,21,76 mg/ m3 respectively. In addition, the number of cardiovascular deaths in 2011-2015 is 52,37,29,31,42 respectively
According to the results, CO as well as other pollutants can adversely affect human health. Due to high levels of air pollution and its related health consequences, particularly cardiovascular disease, should take appropriate measures to reduce air pollution.

according to World Health Organization estimations¡ 3.7 million deaths were attributable to ambient air pollution annually¡ that shows pollutants associated with high rate of mortality and morbidity. So¡ present study with aim of quantifying and estimating health impacts attributable to two pollutant of PM2.5 and CO in 8 industrial cities of Iran during 2011 by AirQ model were performed.
At first¡ required data were taken from Department of Environment in understudy cities. With coding in excel¡ analysis and calculation of statistical parameters was performed for quantifying¡ and information imported to AirQ model. Finally results of total mortality and mortality due to cardiovascular disease presented in tables and graphs format.
According to results¡ with increasing each 10&mug/m3 concentration of PM2.5 and 1mg/m3 increasing in CO¡ risk of mortality increased 1.5% and 0.7% respectively. Cumulative of total mortality attributable to PM2.5 in Isfahan and Shiraz was estimated 585 and 454 cases that this rate is allocated of 5.42% of all deaths in these cities. Sum of cumulative cases of mortality for CO in Isfahan¡ Tehran and Shiraz estimated 14 (2.15%)¡ 24 (0.86 %) and 3 cases (0.69%) respectively.
The study emphasized that PM2.5 and CO as well as other pollutants have adverse affect on human health. Among 8 under study cities¡ Ahwaz had lowest mortality attributable to CO and highest mortality attributable to PM2.5¡ which it can be due to either continuing of days with higher concentration of particulate or higher average of this pollutant in Ahwaz city.
