Raji H, Riahi A, Borsi SH, et al. - Researchers evaluated the risk of hospital admissions attributable to asthma, COPD, and bronchiectasis, in Ahvaz, in correlation with short-term exposure to air pollutants. They used hospital admissions data, as well as data on air pollutants including O₃, NO, NO₂, SO₂, CO, PM₁₀, and PM_2.5 from 2008 to 2018. PM_2.5 was found to be related to a significant rise in hospital admissions for asthma and COPD. In both genders, increased hospital admissions because of bronchiectasis were reported in relation to PM₁₀. For asthma and COPD, an increased risk of hospital admissions related to NO₂ was reported. SO₂ was identified to be related to the risk of hospital admissions of asthma and bronchiectasis. A link existed between CO and hospital admissions for COPD and bronchiectasis. Overall, a significantly increased risk of hospital admissions for asthma, COPD, and bronchiectasis was reported in correlation with short-term exposure to air pollutants in the adult and elderly population.
