Evaluation of short-lived atmospheric fine particles in Tehran, Iran

Fine particles (PM2.5) have adverse impacts and risks on air quality human health. The present research focuses the concentrations of PM2.5, index (AQI), assessment hospital admissions due to COPD attributed PM2.5 particle levels in Tehran during last 10 years from 2011 2020. effects meteorological parameters (i.e., wind speed, humidity, temperature) AQI were examined using data 21 active monitoring stations Air Quality Control Company (AQCC) Mehrabad Meteorological Station. health impact terms chronic obstructive pulmonary disease (COPD) was obtained by AirQ2.2.3 model. Based results, annual average decreased through results also show a significant effect changes concentration. We noticed that reduction concentration 38.55 (AQI = 104.08) 28.59 μg m−3 83.87) 2020 could prevent 779 (by about 70%) premature deaths, estimated number excess cases respiratory system at central relative risk (RR) decade 6158 persons. Also, got unhealthy for sensitive groups people moderate quality. Finally, any can reduce significantly. investigations shown need national clean program policies necessity urgent actions improve Tehran.
