Riacho das Almas, nestled in the state of Pernambuco, Brazil, occupies a position within the semi-arid Agreste region. Its coordinates (-8.1339, -35.6892) place it inland, approximately 80km southwest of Recife, the state capital. The terrain is characterised by rolling hills and plateaus, typical of the transitional zone between the coastal *mata* forests and the drier *sertão* interior. Elevation ranges between 200-400 meters, influencing local wind patterns and contributing to temperature variations. The municipality isn’t directly adjacent to the coast, but is influenced by its proximity, receiving some humidity. Surrounding Riacho das Almas are areas of *caatinga* vegetation, interspersed with small-scale agriculture, primarily subsistence farming focused on crops like cassava and beans. While not a major industrial hub, the region experiences some activity related to sugarcane processing and livestock farming. The urban-rural gradient is pronounced; the town itself is relatively compact, surrounded by a largely rural landscape. This configuration impacts air quality as agricultural practices, including seasonal burning for land clearing, can contribute to particulate matter. The lack of significant industrial emissions is a mitigating factor, but dust from unpaved roads and agricultural activities are key concerns. The prevailing winds, generally from the southeast, can transport pollutants from nearby areas.
Riacho das Almas experiences a distinct wet and dry season, rather than traditional four seasons. Air quality is generally better during the wet season (roughly April to August) due to rainfall effectively scavenging particulate matter from the atmosphere. This period sees increased humidity and reduced dust resuspension. However, even during the wet season, localised pollution from agricultural activities can occur. The dry season (September to March) presents the greatest air quality challenges. Reduced rainfall leads to increased dust levels, particularly from unpaved roads and agricultural land. The drier air also allows for greater concentration of pollutants. February and March are typically the worst months, coinciding with the end of the harvest and increased land preparation for the next planting cycle, often involving controlled burns. Temperature inversions, common during the cooler nights of the dry season, can trap pollutants near ground level, exacerbating conditions. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit strenuous outdoor activity during these periods. Monitoring wind direction is crucial; winds from agricultural areas to the south and east can bring higher pollutant concentrations. Fog, while not frequent, can also trap pollutants during the early morning hours.
