Corabia, nestled in the Olt County of southern Romania (43.7736° N, 24.5033° E), occupies a unique and geographically significant position. The city straddles the river Olt, a major waterway flowing northwards, and lies close to the Romanian border with Bulgaria. This location dictates much of Corabia’s character. The surrounding landscape is predominantly agricultural, characterized by fertile plains and extensive fields used for crop cultivation and livestock farming – a typical feature of the Romanian Plain. The terrain is gently undulating, with the river valley providing a slight depression, influencing local wind patterns and potentially trapping pollutants. Elevation is relatively low, averaging around 80-100 meters above sea level, contributing to stable atmospheric conditions that can exacerbate air quality issues. Corabia’s urban fabric is relatively compact, reflecting its historical role as a river port and trading center. While industrial activity is limited compared to larger Romanian cities, the presence of agricultural processing facilities and smaller workshops contributes to localized emissions. The urban–rural gradient is gradual, with agricultural land seamlessly blending into the city’s periphery. The proximity to the Olt River, while providing a valuable resource and transportation route, can also lead to humidity and fog formation, particularly during cooler months, impacting pollutant dispersion. The broader regional context places Corabia within a zone experiencing increasing agricultural intensification, which can lead to increased ammonia emissions from fertilizer use and livestock operations, impacting regional air quality.

Corabia’s air quality experiences a distinct seasonal cycle heavily influenced by meteorological conditions. Spring (March-May) often sees a gradual improvement as temperatures rise and winds increase, dispersing accumulated pollutants. However, agricultural activities ramp up during this period, leading to elevated ammonia levels from fertilizer application and livestock farming, potentially impacting local air quality. Summer (June-August) typically brings drier conditions and increased sunshine, generally leading to better air quality due to enhanced dispersion. However, heatwaves can create stagnant air masses, trapping pollutants and leading to localized episodes of poorer air quality. Autumn (September-November) is arguably the most challenging season. As temperatures cool, temperature inversions become more frequent, trapping pollutants near the ground, particularly in the mornings. Fog, common during this period due to the river’s humidity, further restricts dispersion. Agricultural burning, a traditional practice in the region, can also significantly contribute to particulate matter pollution during this time. Winter (December-February) brings cold temperatures and frequent fog, creating stable atmospheric conditions that exacerbate pollution. Reduced wind speeds and increased heating demand for residential and commercial buildings further contribute to poorer air quality. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during autumn and winter months, limiting outdoor activity during periods of fog or stagnant air. During the warmer months, while generally better, heatwaves warrant similar precautions.
