Susegana, nestled in the heart of the Veneto region of Italy, presents a unique geographic setting influencing its air quality. Located at coordinates 45.8500, 12.2500, the municipality occupies a hilly terrain within the foothills of the Prealps, approximately 50 kilometers north of Venice and 30 kilometers northwest of Treviso. The landscape is characterized by rolling hills, vineyards, and interspersed patches of woodland, typical of the Prosecco hills. This topography, while aesthetically pleasing, creates conditions conducive to air stagnation, particularly during temperature inversions. Susegana’s elevation, varying between 150 and 350 meters above sea level, further contributes to this effect. The Piave River flows nearby, but its influence on local air circulation is limited by the surrounding hills. The surrounding area is predominantly agricultural, with extensive vineyards dedicated to Prosecco production, alongside smaller areas of intensive farming. While not a major industrial hub, the proximity to industrial zones around Treviso and Conegliano introduces potential for long-range pollutant transport. The urban-rural gradient is relatively sharp, with the town centre transitioning quickly to open countryside, impacting dispersion patterns. This combination of terrain, land use, and regional positioning dictates the specific air quality challenges faced by Susegana.

Susegana’s air quality follows a distinct seasonal pattern. Winter, from December to February, often sees the poorest air quality due to stable atmospheric conditions and increased reliance on wood-burning stoves for heating, contributing to particulate matter (PM) pollution. Temperature inversions are common during these months, trapping pollutants in the valley. Spring (March-May) brings improvement as temperatures rise and wind patterns become more dynamic, dispersing pollutants. However, agricultural activities, including fertilizer application, can lead to ammonia emissions. Summer (June-August) generally experiences the cleanest air, aided by prevailing winds and higher temperatures promoting pollutant dispersion, though ozone formation can be a concern on hot, sunny days. Autumn (September-November) presents a transitional period. The harvest season increases agricultural activity, and the return to heating systems begins, leading to a gradual decline in air quality. Fog, common in autumn mornings, can exacerbate particulate matter concentrations. Sensitive individuals – children, the elderly, and those with respiratory conditions – should limit strenuous outdoor activity during winter and autumn mornings. Monitoring pollen levels is also advisable during spring. Avoiding peak hours near agricultural areas during fertilizer application is recommended.
