Industrialization and the growing of urbanization have increased the amount of contamination and have a devastating impact on the population health; the aim of this study was the relationship between pollutants and some climatic parameters on mortality of heart and respiratory diseases in Shiraz
Methods: The study was an analytical one. Firstly, daily data on climate elements (temperature, humidity, pressure, wind) from Shiraz Meteorological Office (2004-2014), daily information on air pollutants (CO, PM, NO2, SO2, O3) from Shiraz General Environment Department and cardiovascular and respiratory mortality rates from Shiraz University of Medical Sciences was collected, respectively. Data were analyzed using software SPSS ver. 22; statistical methods and correlation coefficients of monthly, seasonal and monthly averages and mortality rates were investigated.
Results: Results of this study indicated that there was a significant correlation between the parameters of the climate (humidity, pressure, temperature and wind) and deaths from cardio - vascular and respiratory diseases at the level of 0.99 and 0.95 (**=P<0/01, *=P<0/05). There was a statistical difference between the mortality rates in different seasons in Shiraz and the mortality rates caused by the cardio vascular and respiratory diseases were relatively more sensitive to climate parameters.
Conclusion: In general, during the statistical period, no polluted day was observed in polluted O3, NO2 in Shiraz City, relationships between other pollutants and mortality rates were significant. This correlation is shown by a 1-5 day delay for pollutants of CO, PM10and 6-10 days for pollutants of SO2.
