An investigation of particulate matter and relevant cardiovascular risks in Abadan and Khorramshahr in 2014–2016

Abstract

Over the last decades, air pollution has been regarded as one of the major environmental problems. Cardiovascular and respiratory diseases are among the most common illnesses arising from air pollution and dust storm. Nowadays, non-communicable diseases resulting from air pollution have affected many people around the world. In recent years, the cities of Abadan and Khorramshahr, located in the southwestern Iran have been adversely affected by air pollution and dust storm. To address the issue, this study set out to investigate the relationship between hospital admissions for cardiovascular diseases and dust storms in Abadan and Khorramshahr in 2014–2016. The data was collected by the Abadan Environmental Protection Agency (Abadan EPA) office. The monitoring station is fully automated and provides hourly particulate matter (PM10) concentrations using a β-ray absorption monitor (Met One Model BAM-1020-Continuous Beta, USA). The annual PM10 mean concentrations reached 169, 187 and 201 µg/m3 in 2014, 2015, and 2016, respectively. The number of people suffering from cardiovascular diseases attributed to PM10 during this period was 237, 259, and 274, respectively. The results showed that high levels of particulate matter (PM) in the air drastically increased the number of people with cardiovascular diseases. The results also revealed that there was a significant relationship between concentrations of PM10 in dusty days and the cases of cardiovascular diseases in Abadan and Khorramshahr. According to the results of the study, an increase in the exposure concentrations of particulate matter could potentially cause different health problems.
