Bequimão, a municipality nestled within the state of Maranhão, Brazil, occupies a significant position in the country’s northeastern region. Located at approximately -2.4489 latitude and -44.7828 longitude, the city’s geography is defined by its proximity to the Pindaré River, a major waterway influencing local climate and transportation. The terrain is generally flat, characteristic of the Amazon-Guiana Shield’s coastal plain, with elevations rarely exceeding 50 meters. This low-lying landscape contributes to limited natural air dispersion. Bequimão’s urban character is that of a developing inland city, with a population of around 19,584, experiencing a gradual urban-rural gradient as it transitions into surrounding agricultural lands. The region is heavily reliant on agriculture, particularly subsistence farming and small-scale plantations of crops like rice and beans. While not a major industrial hub, localized processing of agricultural products and limited construction activity contribute to particulate matter emissions. The surrounding landscape is dominated by dense tropical rainforest, interspersed with areas of cleared land for agriculture. The city’s location within the Amazon basin means high humidity and significant rainfall, impacting pollutant washout but also fostering conditions for mold and biological aerosols. The lack of substantial elevation hinders atmospheric mixing, potentially trapping pollutants near ground level.
Bequimão experiences a distinct wet and dry season, rather than traditional four seasons. Air quality fluctuates dramatically with these shifts. The dry season, typically from June to November, sees a peak in particulate matter pollution. Reduced rainfall means less atmospheric cleansing, and agricultural burning for land preparation becomes prevalent, releasing significant smoke and ash. Dust from unpaved roads also contributes. August and September are particularly challenging months for respiratory health. Conversely, the wet season (December to May) brings a significant improvement in air quality. Frequent and heavy rainfall effectively washes pollutants from the atmosphere. However, the high humidity during this period fosters the growth of mold and mildew, potentially exacerbating respiratory issues for sensitive individuals. Temperature inversions, common during the calmer nights of the dry season, trap pollutants close to the ground, worsening air quality. Wind patterns, generally easterly trade winds, can occasionally bring smoke from distant wildfires. Sensitive groups – children, the elderly, and those with pre-existing respiratory conditions – should limit outdoor activity during the peak of the dry season and monitor their health closely. Maintaining good indoor ventilation is crucial year-round.
