Carangola, nestled in the southern reaches of Minas Gerais, Brazil, occupies a geographically significant position within the Zona da Mata e Serras region. Located at approximately -20.7328° latitude and -42.0289° longitude, the city sits at an elevation of around 850 meters (2,789 feet) above sea level, contributing to a generally temperate climate. The surrounding landscape is characterized by rolling hills and valleys, a typical feature of the Brazilian highlands. This terrain influences local wind patterns, often creating localized areas of stagnant air, particularly within the urban core. Carangola is situated near the headwaters of the Rio Donana, a tributary of the Rio Doce, providing a crucial water source and influencing humidity levels. The urban fabric of Carangola is a blend of historical colonial architecture and more modern development, reflecting its evolution from a rural settlement to a regional commercial hub. Agriculture plays a vital role in the surrounding economy, with coffee cultivation being particularly prominent. This proximity to agricultural lands introduces potential sources of particulate matter, especially during harvesting and processing seasons. The urban–rural gradient is relatively gradual, with smaller agricultural communities and rural settlements interspersed throughout the landscape. The city’s location within a mountainous region can exacerbate air pollution episodes; topographic features can trap pollutants, leading to higher concentrations, especially during periods of thermal inversion. The absence of major heavy industries within Carangola itself mitigates some pollution risks, but regional transport corridors and agricultural practices remain key factors influencing air quality.

Carangola’s tropical climate exhibits a distinct wet and dry season pattern, significantly impacting air quality throughout the year. The dry season, typically spanning from April to September, often sees a reduction in overall rainfall, leading to lower humidity and increased solar radiation. While this might seem beneficial, the drier conditions can exacerbate particulate matter pollution. Agricultural burning, a common practice for land clearing and crop residue removal, becomes more prevalent during this period, releasing significant amounts of smoke and particulate matter into the atmosphere. The lack of rainfall to wash away these pollutants, coupled with potential temperature inversions trapping cooler air near the ground, can lead to periods of reduced visibility and elevated air pollution. Conversely, the wet season (October to March) brings frequent rainfall, which naturally cleanses the air, reducing particulate concentrations. However, heavy rainfall can also lead to increased levels of biological allergens, impacting respiratory health. Fog, particularly during the transition months, can also trap pollutants, creating localized air quality concerns. During the dry months of July and August, outdoor activities should be approached with caution, especially for individuals with respiratory conditions. The wettest months, January and February, generally offer the best air quality, though pollen allergies may be a concern. Sensitive groups, including children, the elderly, and those with pre-existing respiratory illnesses, should monitor local conditions and limit outdoor exposure during periods of agricultural burning or fog.
