Morón, nestled within the province of Buenos Aires, Argentina, occupies a geographically significant position within the Pampas region. Located approximately 30 kilometers southwest of the capital city, Buenos Aires, it sits at an elevation of roughly 25 meters (82 feet) above sea level, contributing to a relatively flat terrain characteristic of the surrounding plains. The city’s urban fabric is interwoven with remnants of the original pampas landscape, evidenced by scattered grasslands and occasional drainage canals reflecting the area’s historical agricultural use. Morón’s proximity to Buenos Aires places it within the metropolitan area’s urban sprawl, experiencing a gradual urban–rural gradient as one moves outwards. To the west, the landscape transitions into more extensive agricultural fields, primarily dedicated to cattle ranching and crop cultivation, which can occasionally contribute to particulate matter through agricultural practices. The Quilmes River, a modest waterway, flows nearby, influencing local microclimates and drainage patterns. The prevailing winds generally originate from the southeast, carrying air masses from the Atlantic Ocean, which can both cleanse the air and, under certain conditions, transport pollutants from the larger Buenos Aires conurbation. Industrial activity, though less concentrated than in the core of Buenos Aires, is present in Morón, particularly in manufacturing and light industry, adding to localized pollution sources. The flat topography and surrounding agricultural lands can exacerbate the accumulation of pollutants, especially during periods of stagnant air.

Morón’s air quality experiences a distinct seasonal cycle heavily influenced by regional weather patterns. Summer (December-February) typically brings warmer temperatures and increased sunshine, but also a higher risk of stagnant air conditions, particularly during prolonged heatwaves. This can trap pollutants released from both urban and agricultural sources, leading to periods of reduced visibility and potential respiratory discomfort. Autumn (March-May) often sees a gradual improvement in air quality as temperatures cool and wind patterns become more variable, dispersing pollutants more effectively. However, agricultural burning practices, though regulated, can occasionally contribute to elevated particulate levels. Winter (June-August) generally presents the most challenging period for air quality. Cold, stable air masses frequently lead to temperature inversions, where a layer of warm air sits above cooler air near the ground, preventing vertical mixing and trapping pollutants close to the surface. Fog, common during these months, further exacerbates this issue. Spring (September-November) usually marks a significant improvement, with increased wind speeds and rainfall helping to flush out accumulated pollutants. Sensitive groups, including children, the elderly, and individuals with pre-existing respiratory conditions, should exercise caution during winter and summer, limiting outdoor exertion during periods of poor air quality. Monitoring local weather forecasts and air quality reports is crucial for informed decision-making regarding outdoor activities. Avoiding peak traffic hours and utilizing public transportation can also contribute to minimizing personal exposure.
