Air pollution is an important environmental issue due to its proven serious impacts on human health. The purpose of this study was to investigate the concentration of suspended particles (PM2.5 and PM10) and its relationship with the rate of death due to cardiovascular and respiratory diseases in Susangard during 2014-2016.

This study was performed cross -sectional to assess health impacts of PM2.5 and PM10 by using Air Q software.

The results showed that the highest annual average concentration was of PM2.5 and PM10 in 2016, which consisted of 58.07 and 356.89 μg/m3, respectively. The highest and lowest average concentration of PM2.5 was observed in April and December, respectively, and the highest and lowest average concentration of PM10 in July and November. Daily analysis showed that there was 178 dusty out of three years of the study, the most severe dust day occurred in 2016. Percentage of overall mortality attributed to PM2.5 in people over 30 years of age according to the estimate of the average relative risk in 2014-16 equal to 25.23%, 20.6% and 24.21%, The mortality attributed to ischemic heart disease was 62.87%, 60.74% and 43.62%, respectively.

The results indicate that the health effects attributed to PM2.5 included mortality for all-causes, cardiovascular and respiratory deaths in the city of Susangerd, which requires more attention from officials and specialists to control air pollution.

Waste management is one of the ways to reduce the environmental and health effects of human activities, however sometimes it causes environmental and health problems.Therefore, knowing the quality and quantity of pollutants released from waste management facilities will make its remedial solutions more effective.In this study, the air concentration of particulate matter (PM) in Aradkooh waste management facility of Tehran and its surrounding area was investigated.

In this cross-sectionalstudy, PM2.5and PM10were measured with a portable analyzer and samples were taken from 5 points inside and 3 points outside the waste management facility. The sampling was in the summer of 2020 in two consecutive weeks. Ethicalconsiderations were observed in all stages of the study.

The mean values of PM2.5were significantly different by sampling site (pvalue <0.05).The mean values of PM2.5and PM10in processing unit were higher than other points and were 405 and 1048 μg/m3, respectively.The mean values of PM2.5in Shurabad and Mahdiabad were 25 and 35 μg/m3, respectively.The mean values of PM in most cases violated the standard of ambient air quality in Iran.

According to the results of this study, it was not possible to determine the specific origin of PM, but it seemed that in addition to waste management operations, other factors such as traffic, local dust and unknown sources affected the concentration of PM. The results showed that the environmental protection measures inside and around the waste management facility is essential to reduce air pollution, especially PM.
