Researchers from the Faculty of Biotechnology and the Faculty of Exact and Technical Sciences at the University of Rzeszów are examining what is actually “delivered” to the air over Rzeszów during Saharan dust intrusions. Even when conventional air quality standards remain within acceptable limits, the composition of the atmosphere can change in a way that is not immediately visible in routine measurements. Saharan dust events carry ultrafine particles and reactive oxygen species, including free radicals, which may exert harmful effects on the human body. These episodes therefore go beyond the familiar “yellow sky” phenomenon, representing subtle but meaningful changes in air quality with potential health implications.
The research also contributes to the United Nations Sustainable Development Goals, particularly SDG 3 (Good Health and Well-being), SDG 11 (Sustainable Cities and Communities), and SDG 13 (Climate Action), by improving understanding of air pollution, urban air quality, and the atmospheric processes influenced by a changing climate.
