Ecoporanga, nestled in the southern region of Espírito Santo, Brazil, occupies a unique geographic position within a transitional landscape. Located at approximately -18.3728° latitude and -40.8308° longitude, the city sits at an elevation of roughly 150 meters above sea level, influencing local climate and air circulation patterns. The surrounding terrain is characterized by a blend of rolling hills and valleys, part of the broader Atlantic Forest biome, though significant portions have been converted to agricultural land, primarily for cocoa and coffee cultivation. The Rio Jequitinhonha, a vital waterway, flows nearby, moderating temperatures and contributing to localized humidity. Ecoporanga’s position along the edge of the Jequitinhonha River valley creates a microclimate susceptible to temperature inversions, particularly during drier periods. The urban fabric is relatively compact, reflecting its smaller population of just under 22,000. While not directly adjacent to major industrial belts, the agricultural activity in the surrounding region, including the use of fertilizers and pesticides, and occasional burning of agricultural waste, can contribute to localized air pollution. The urban–rural gradient is gradual, with small-scale farming and rural settlements blending seamlessly into the city’s periphery. Prevailing winds generally flow from the east, bringing moisture from the Atlantic Ocean, but their impact on air quality is often modulated by the topography and local weather conditions. The Atlantic Forest, though diminished, still provides some natural air filtration, but its effectiveness is limited by fragmentation and the scale of agricultural practices.

Ecoporanga experiences a tropical climate with distinct wet and dry seasons, significantly impacting air quality throughout the year. The wet season, typically spanning from November to March, brings frequent rainfall and high humidity, generally leading to improved air quality as precipitation washes away particulate matter and dilutes pollutants. However, periods of intense rainfall can also lead to increased mold and fungal spore concentrations, affecting respiratory health. The dry season, from April to October, is characterized by lower rainfall, higher temperatures, and increased sunshine. This period often sees a rise in air pollution, particularly during September and October, due to the increased use of agricultural burning to clear land for planting. Temperature inversions, common during the cooler nights of the dry season, trap pollutants near the ground, exacerbating the problem. Fog, though infrequent, can also worsen air quality by reducing atmospheric mixing. During the wettest months (January and February), outdoor activities are generally favorable, though those with respiratory sensitivities should remain vigilant for mold. The months of September and October present the greatest risk, with agricultural burning contributing to elevated particulate matter. Sensitive groups, including children, the elderly, and individuals with pre-existing respiratory conditions, should limit prolonged outdoor exposure during these periods and consider wearing masks when air quality is visibly affected. Maintaining indoor air quality through proper ventilation and air filtration is also recommended throughout the year, but especially during the dry season.
