Nazaré da Mata, nestled in the Zona da Mata region of Pernambuco, Brazil, occupies a geographically significant position within a transitional landscape. Located at approximately -7.7419° latitude and -35.2278° longitude, the city sits at a relatively low elevation, averaging around 350 meters above sea level, contributing to a warmer, more humid climate. The surrounding terrain is characterized by rolling hills and valleys, typical of the Mata Atlântica biome, though significant portions have been converted to agricultural land and pasture. The city’s proximity to the Atlantic Ocean, roughly 30 kilometers to the east, influences local weather patterns and introduces a maritime influence, moderating temperatures but also potentially impacting air quality through salt spray and coastal breezes. Nazaré da Mata is part of an urban–rural gradient, transitioning from the denser urban core towards agricultural areas dominated by sugarcane cultivation and smaller-scale farming. This agricultural activity, particularly sugarcane processing, represents a potential source of localized air pollution, including particulate matter and volatile organic compounds. The Zona da Mata itself is a densely populated region, and Nazaré da Mata’s location within this zone means it is susceptible to regional pollution transport from larger urban centers like Recife. The landscape’s undulating nature can also create localized microclimates, influencing the dispersion of pollutants and potentially leading to areas of higher concentration. The surrounding forests, though diminished, still play a role in air filtration, but their effectiveness is limited by the extent of deforestation and agricultural expansion.

Nazaré da Mata experiences a tropical climate with distinct wet and dry seasons, significantly impacting air quality dynamics. The wet season, typically spanning from March to August, brings frequent rainfall and increased humidity. While the rain naturally helps to cleanse the atmosphere by washing away particulate matter, the increased humidity can exacerbate respiratory issues for sensitive individuals. The dry season, from September to February, is characterized by lower rainfall and higher temperatures, often leading to a build-up of pollutants. During this period, stagnant air masses are more common, particularly during the months of November and December, hindering the dispersion of emissions from agricultural activities and local industries. Temperature inversions, where a layer of warm air traps cooler air near the ground, can also occur, further concentrating pollutants. The sugarcane harvest season, which often coincides with the dry season, contributes significantly to air pollution through the burning of fields, releasing substantial amounts of smoke and particulate matter. February and March, as the wet season approaches, often see a gradual improvement in air quality as rainfall increases. Individuals with respiratory conditions, such as asthma or bronchitis, should exercise caution during the dry season, particularly during periods of stagnant air or agricultural burning. Children and the elderly are also more vulnerable and should limit prolonged outdoor exposure during these times. Staying indoors with air filtration systems and monitoring local weather conditions can help mitigate potential health risks.
