Jaguapitã, nestled within the state of Paraná, Brazil, occupies a geographically significant position within the broader Ponta Grossa metropolitan area. Located at approximately -23.1128° latitude and -51.5319° longitude, the city sits on a gently undulating plateau characteristic of the Paraná region, an area historically shaped by basaltic lava flows. The elevation averages around 950 meters (3,117 feet) above sea level, contributing to a relatively cool climate compared to coastal Brazilian cities. The surrounding landscape is a mosaic of agricultural land, primarily dedicated to soybean, maize, and sugarcane cultivation, interspersed with patches of native Cerrado vegetation, a savanna biome. This agricultural intensity introduces potential sources of particulate matter and volatile organic compounds (VOCs) into the local atmosphere, particularly during planting and harvesting seasons. To the west, the landscape gradually transitions into more forested areas, offering some natural air filtration. Jaguapitã’s proximity to Ponta Grossa, a larger industrial and commercial hub, means it experiences some spillover effects from that city’s pollution sources, though the distance mitigates the impact. The urban–rural gradient is relatively sharp, with the city’s built environment quickly giving way to agricultural fields and scattered rural settlements. The lack of major rivers directly adjacent to Jaguapitã limits the natural cleansing effect of waterways on air pollutants, making meteorological conditions and regional agricultural practices particularly influential on air quality.

Jaguapitã’s subtropical climate dictates a distinct seasonal pattern in air quality. The region experiences a wet and a dry season, rather than the four traditional seasons. During the dry season, typically from April to September, lower rainfall and increased sunshine hours contribute to a build-up of pollutants. Temperature inversions, common during these cooler months, trap pollutants near the ground, exacerbating localized air quality issues. Agricultural burning, often practiced to clear land for planting, is a significant contributor to particulate matter pollution during this period, particularly in May and June. The prevailing winds, generally from the east, can carry pollutants from surrounding agricultural areas into the city. Conversely, the wet season, from October to March, brings increased rainfall and higher humidity, which naturally washes away particulate matter and helps disperse gaseous pollutants. Stronger winds associated with convective storms also aid in ventilation. Fog, occasionally occurring during the cooler mornings of the dry season, can significantly reduce visibility and trap pollutants, creating temporary pockets of poor air quality. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during the dry season, particularly on days with agricultural burning or fog. Limiting outdoor exertion and avoiding areas near agricultural fields are advisable. During the wet season, while overall air quality is generally better, periods of heavy rainfall can still lead to localized flooding and the release of mold spores, impacting indoor air quality.
