Canapi, nestled in the state of Alagoas, Brazil, occupies a geographically significant position within the Northeast region. Located at approximately -9.1269 latitude and -37.6050 longitude, the city’s terrain is characterized by a gently undulating landscape transitioning from coastal plains to the foothills of the Borborema Plateau. This proximity to the Atlantic Ocean exerts a considerable influence on the local climate and, consequently, air quality. The surrounding landscape is a mosaic of sugarcane plantations, small-scale agriculture, and patches of Atlantic Forest, a biodiversity hotspot. Canapi sits within a predominantly rural-agricultural zone, with a gradual urban–rural gradient extending outwards. The city itself exhibits a relatively compact urban footprint, typical of smaller Brazilian municipalities, with a central area radiating outwards. Elevation plays a minor role, with most of the city situated at low altitudes, minimizing the potential for significant terrain-induced air stagnation. While Canapi isn't directly adjacent to major industrial belts, the regional agricultural activity, particularly sugarcane processing, contributes to localized emissions. The prevailing winds, generally easterly, often carry moisture from the Atlantic, which can influence pollutant dispersion and create conditions conducive to fog formation, potentially trapping pollutants near the surface. The Rio Canapi, which flows through the municipality, also impacts local humidity and microclimates, influencing the behaviour of airborne particles. The city’s location, therefore, presents a unique interplay of coastal influences, agricultural practices, and a developing urban environment, all shaping its air quality profile.

Canapi’s tropical climate dictates a distinct wet and dry season pattern, profoundly impacting its air quality throughout the year. The dry season, typically spanning from August to January, is characterized by reduced rainfall and increased sunshine hours. This period often sees a slight increase in particulate matter concentrations, primarily due to agricultural burning practices associated with sugarcane harvesting and land preparation. While winds remain generally easterly, the lack of rainfall allows these particles to persist for longer durations. Temperature inversions, though not as frequent as in more temperate climates, can occasionally occur during the cooler nights of the dry season, trapping pollutants closer to the ground. The wet season, from February to July, brings frequent rainfall and higher humidity, naturally cleansing the atmosphere and significantly reducing particulate pollution. The increased rainfall effectively ‘washes’ pollutants from the air, leading to improved air quality. However, periods of intense rainfall can also lead to increased levels of biological allergens, impacting respiratory health. During the transition months (January/February and July/August), fluctuating weather patterns can result in unpredictable air quality variations. Sensitive groups, such as children, the elderly, and individuals with pre-existing respiratory conditions, should exercise caution during the dry season, particularly during periods of agricultural burning. Outdoor activities are generally more favourable during the wet season, although pollen allergies should be considered. Monitoring local weather forecasts and agricultural activity reports can provide valuable insights into potential air quality fluctuations, allowing for proactive health management.
