Assessment of odorous VOCs released from a main MSW landfill site in Istanbul-Turkey via a modelling approach

---

Abstract.
An air pollution modeling study was conducted to investigate the odorous effects of volatile organic
compounds (VOCs) emissions from a sanitary landfill area on ambient air quality. The atmospheric dispersion
of hydrogen sulfide (H2S) and 22 VOCs was modeled. Industrial Source Complex v3 Short Term (ISCST3) model was used to estimate hourly concentrations of odorous VOCs over the nearest residential area. Odor thresholds of VOCs of interest were also found in the literature. Results showed that shortterm averages of three odorous VOCs, namely ethyl mercaptan, methyl mercaptan and hydrogen sulfide, exceeded their odor thresholds, which are reported to be 0.022, 0.138 and 11.1 ug/m3, respectively, at several points within the domain. Their highest concentrations within Gokturk Countywere estimated to be 0.09387 ug/m3 for ethyl mercaptan, 0.07934 ug/m3 formethyl mercaptan and 6.315 ug/m3 for hydrogen sulfide. Short-term model results revealed the occasional odor problems being reported for Gokturk County. Hourly concentrations were used to obtain frequencies of odor episodes in Gokturk County via a probability analysis. The results showed that ethyl mercaptan concentrations did not exceed its odor threshold during more than 8.84% of the time. Similarly, the maximum odor episode frequencies for methyl mercaptan and hydrogen sulfide were 0.98% and 0.34% of the time, respectively.
