Rio Azul, nestled in the state of Paraná, Brazil, at coordinates -25.7328, -50.7958, is a small city of approximately 14,025 inhabitants. Its geography is defined by the rolling hills and undulating terrain characteristic of the second Paraná Plateau. The city’s elevation, around 550 meters above sea level, contributes to localized weather patterns and influences air dispersion. Rio Azul is situated within a predominantly agricultural region, heavily reliant on soybean, corn, and wheat cultivation, with increasing presence of livestock farming. This agricultural activity is a key determinant of air quality, contributing particulate matter from field preparation, harvesting, and the use of agricultural chemicals. The Ivaí River flows nearby, offering a potential source of moisture but also acting as a conduit for pollutants during periods of low flow. The urban-rural gradient is relatively sharp, with the city centre transitioning quickly to expansive farmland. While not a major industrial hub, smaller-scale processing of agricultural products occurs within and around Rio Azul, adding to potential emission sources. The surrounding landscape is largely composed of Atlantic Forest remnants, though these are fragmented and under pressure from agricultural expansion. This geographical context creates a unique set of challenges for maintaining clean air.
Rio Azul experiences a humid subtropical climate, with distinct wet and dry seasons rather than traditional four seasons. Air quality generally deteriorates during the dry season (roughly May to September). This is due to reduced rainfall, leading to increased dust resuspension from agricultural lands and a decrease in the natural scavenging of pollutants from the atmosphere. Agricultural burning, often used for land clearing, is most prevalent during this period, significantly impacting particulate matter levels. Temperature inversions, common during cooler, calmer nights, trap pollutants near the ground, exacerbating the issue. The wet season (October to April) typically brings improved air quality, as rainfall washes away pollutants and increases humidity, suppressing dust. However, intense rainfall events can also lead to runoff carrying agricultural chemicals into waterways, indirectly affecting air quality through volatilization. November and December often see higher humidity and calmer winds, potentially leading to localized pollutant build-up. Sensitive individuals, such as children and the elderly, should limit strenuous outdoor activity during dry periods and be mindful of agricultural burning. Monitoring wind direction is crucial, as pollutants can travel considerable distances from burning fields.
