Abstract
We conducted a modified case-crossover study to examine whether wildfires in the Paraná River Delta departments surrounding Rosario, Argentina, during 2021-2022 increased PM₂.₅ concentrations in this city and if this rise subsequently elevated the risk of ST-elevation myocardial infarction (STEMI). We first observed that daily PM₂.₅ levels in Rosario were significantly higher on wildfire days compared to non-wildfire days (34 µg/m3 vs. 25.75 µg/m3, p < 0.01). In the case-crossover analysis, we found that the odds of STEMI were significantly higher on days when PM₂.₅ concentrations exceeded 20 µg/m3 (OR 2.2 [95% CI 1.2-4.2, p = 0.02]). Additionally, the odds of STEMI increased with higher PM₂.₅ concentrations, with a significant difference when comparing the first and fourth quartiles concentration (OR 1.76 [95% CI 1.06-2.92, p = 0.03] and OR 2.02 [95% CI 1.25-3.27, p < 0.01], respectively). In conclusion, wildfires in the surrounding departments of Rosario City in the Paraná River Delta led to elevated PM₂.₅ levels, and this increase was associated with a higher risk of STEMI hospital admissions.
期刊介绍:
International Journal of Environmental Health Research ( IJEHR ) is devoted to the rapid publication of research in environmental health, acting as a link between the diverse research communities and practitioners in environmental health. Published articles encompass original research papers, technical notes and review articles. IJEHR publishes articles on all aspects of the interaction between the environment and human health. This interaction can broadly be divided into three areas: the natural environment and health – health implications and monitoring of air, water and soil pollutants and pollution and health improvements and air, water and soil quality standards; the built environment and health – occupational health and safety, exposure limits, monitoring and control of pollutants in the workplace, and standards of health; and communicable diseases – disease spread, control and prevention, food hygiene and control, and health aspects of rodents and insects. IJEHR is published in association with the International Federation of Environmental Health and includes news from the Federation of international meetings, courses and environmental health issues.
