Kampenhout, nestled within the Flemish countryside of Belgium, occupies a geographically significant position within the broader Mechelen-Brussels economic corridor. Located at approximately 50.94°N, 4.55°E, the municipality’s terrain is predominantly flat, characteristic of the Campine region, a gently undulating landscape formed by glacial deposits during the Pleistocene epoch. This flatness, while aesthetically pleasing, contributes to air quality challenges as it limits natural dispersion of pollutants. Kampenhout sits on the edge of the Hagelandse Heuvelrug, a low ridge offering some localized relief, but its overall low elevation (averaging around 20-40 meters above sea level) restricts vertical mixing of air. The surrounding landscape is a patchwork of agricultural fields – primarily used for arable farming and pasture – interspersed with woodlands and scattered villages. This agricultural activity, particularly during planting and harvesting seasons, can contribute to particulate matter pollution. Kampenhout’s proximity to the industrial belt surrounding Brussels, though not directly adjacent, means it is susceptible to long-range transport of pollutants from larger urban and industrial centers. The urban–rural gradient is gradual; Kampenhout retains a distinctly rural character, but its accessibility via road networks connects it to the denser urban areas. The absence of major waterways within the immediate vicinity limits the potential for evaporative cooling and influences local humidity, impacting atmospheric stability and pollutant behaviour. The soil composition, largely sandy loam, also influences dust generation and the deposition of airborne particles.

Kampenhout’s air quality experiences a distinct seasonal cycle heavily influenced by meteorological conditions. Winter months (December-February) often present the most challenging period. Temperature inversions, common during this time, trap pollutants close to the ground, exacerbating existing emissions from residential heating (primarily wood and gas) and agricultural activities like livestock farming. Fog, frequently occurring in winter due to the region’s humidity and relatively low temperatures, further restricts dispersion. Spring (March-May) sees a gradual improvement as temperatures rise, and wind speeds increase, aiding in pollutant dispersal. However, agricultural practices, including the spreading of fertilizers and the use of machinery, can temporarily elevate ammonia and particulate matter levels. Summer (June-August) generally offers the best air quality, with consistent winds and higher temperatures promoting good ventilation. However, periods of prolonged heat can lead to stagnant air conditions and ozone formation, particularly during sunny days. Autumn (September-November) marks a transition period, with decreasing temperatures and increasing humidity. Harvest activities and the return to heating systems contribute to a gradual decline in air quality, mirroring the winter pattern. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during winter and early spring, limiting prolonged outdoor exposure on days with persistent fog or temperature inversions. During warmer months, monitor for ozone alerts and adjust outdoor activities accordingly. Agricultural workers should be particularly mindful of exposure to dust and ammonia during peak farming seasons.
