PM10 and PM2.5 emission and analysis from residential complex construction site in Sremska Kamenica, Serbia [elektronikus dokumentum] / Cavic Aleksandra M. University of Szeged Szeged 2025 282-285 Proceedings of the International Symposium on Analytical and Environmental Problems 31 Construction sites are recognized as significant non-industrial sources of particulate matter (PM10 and PM2.5), contributing to the degradation of urban air quality and posing health risks for workers and nearby residents. The research quantified emissions from a residential complex construction site in Sremska Kamenica, Serbia, by applying the EMEP/EEA Air Pollutant Emission Inventory Guidebook (Tier 1 methodology). The active construction area was defined as 3,500 m², operating under a continuous 365-day work schedule. Annual emissions were estimated at 207 kg for PM10 and 59.5 kg for PM2.5, corresponding to daily emissions of 568 g and 163 g, respectively. Dispersion modeling using a box approach yielded hourly average concentrations of 112 µg/m³ for PM10 and 11.2 µg/m³ for PM2.5. Risk assessment, based on a 10-hour work shift and an inhalation rate of 1.25 m³/h, indicated daily doses of 1,400 µg of PM10 and 140 µg of PM2.5 per worker. When compared with WHO Air Quality Guidelines, PM2.5 remained within acceptable levels, while PM10 concentrations exceeded recommended thresholds by more than 2.5 times, yielding a Hazard Quotient of 2.49. These findings identify PM10 as the dominant polluting substance of concern, highlighting the necessity of implementing dust suppression measures such as watering, soil stabilization, vehicle speed control, and protective equipment.
