Jacqueville, nestled within the Lagunes region of Ivory Coast at coordinates 5.2000° N, -4.4167° W, occupies a geographically significant position along the Atlantic coastline. The city’s urban fabric is interwoven with the landscape, transitioning from a coastal fringe to a gradually rising terrain inland. Its location on the edge of the Ebrie Lagoon, a vital waterway, influences local microclimates and contributes to humidity levels. The surrounding landscape is a mosaic of coastal scrub, mangrove forests, and small-scale agricultural plots, primarily focused on cocoa and plantain cultivation. This agricultural activity, while crucial to the regional economy, can contribute to localized air pollution through the burning of agricultural waste and the use of fertilizers. The urban–rural gradient is relatively sharp; Jacqueville itself is a moderately sized town, but it’s surrounded by smaller villages and rural areas, creating a blend of urban and agricultural influences. The elevation is generally low, rarely exceeding 30 meters above sea level, which can exacerbate the trapping of pollutants, particularly during periods of stagnant air. Further inland, the terrain gently slopes towards the forested hills of the Lagunes region, impacting prevailing wind patterns and potentially influencing the dispersal of airborne contaminants. The proximity to Abidjan, Ivory Coast’s largest city and a major industrial hub, means Jacqueville is susceptible to the advection of pollutants from that urban center, particularly during certain weather conditions. The coastal breezes, however, typically offer some degree of natural ventilation.

Jacqueville’s tropical climate dictates a distinct wet and dry season pattern, profoundly impacting air quality. The dry season, typically spanning from November to March, often sees a slight increase in particulate matter. While rainfall is minimal, the reduced humidity allows for greater dispersion of dust originating from agricultural lands and construction sites. However, the lack of frequent rain also means pollutants linger longer. The wet season, from April to October, brings frequent rainfall, which naturally helps to cleanse the atmosphere, washing away particulate matter and reducing overall pollution levels. During this period, the high humidity can trap certain gaseous pollutants closer to the ground. The Harmattan winds, a dry, dusty trade wind blowing from the Sahara Desert, occasionally impact Jacqueville during the dry season, carrying fine particulate matter and reducing visibility. Temperature inversions, though less frequent than in temperate climates, can occur during cooler nights, trapping pollutants near the surface. Months like February and March, coinciding with the end of the dry season and the beginning of agricultural activities, may present slightly elevated air quality concerns. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during these periods, limiting strenuous outdoor activity and monitoring for any adverse health effects. The increased humidity during the wet season can exacerbate respiratory issues for some, so maintaining indoor air quality is also important. Overall, the wet season offers a respite from poorer air quality, while the dry season requires greater vigilance regarding potential pollution sources.
