Sažetak

To evaluate the impact of meteorological conditions on air quality in the vicinity of the Prudinec/Jakuševec landfill in Zagreb, daily concentrations of particulate matter (PM₁₀), hydrogen sulphide (H₂S), and ammonia (NH₃), monitored over a five-year period (2020–2024), were analysed. Under meteorological conditions in which the mixing layer height (MLH) falls below 1,000 m, an inversion layer forms above the city, suppressing vertical air mixing and leading to atmospheric stability and pollutant accumulation. The results showed that nearly 80 % of stable conditions occurred during the cold season (autumn and winter) of the study period. During these stable episodes, 88 % of all daily PM₁₀ limit exceedances and 70 % of H₂S exceedances were recorded. Comparable PM₁₀ concentrations were measured at several monitoring stations across Zagreb, suggesting that the landfill is not a dominant source of PM₁₀ pollution. The seasonal pattern of H₂S concentrations at the landfill showed higher levels during winter, opposite to the pattern observed at the nearby Central Wastewater Treatment Plant of the City of Zagreb (CUPOVZ).
This behaviour indicates the landfill is most likely a specific local source of H₂S. NH₃ concentrations were higher during the warm season both near the landfill and at CUPOVZ, suggesting different dominant emission sources. The differing seasonal patterns of PM₁₀, H₂S, and NH₃ indicate that these pollutants originate from distinct dominant emission sources. In the south-eastern part of Zagreb, agriculture and livestock farming are likely among the main contributors to NH₃ emissions.
