Assessment of air pollutant emissions from the Akrotiri landfill site (Chania, Greece).
Air pollutants emitted from landfills affect air quality, contribute to the greenhouse effect and may cause serious problems to human health under certain circumstances. The current study was focused on the determination of air emissions from the Akrotiri landfill site which is located in the Akrotiri area (Chania, Greece). The landfill consists of two phases, phase A (first phase) which is currently closed (operational between 2003 and 2007) and phase B (second phase, operation between 2007 and (foreseen) 2013). Three different emission models (the EPA LandGEM model, the triangular model and the stoichiometric model) were used for the quantification of emissions. The LandGEM 3.02 software was further adopted and used in conjunction with the long-term dispersion model ISC3-LT for the evaluation of the dispersion of gaseous chemical components from the landfill. The emission and meteorological conditions under which the models were applied were based on the worst-case emission scenario. Furthermore, the concentration of hydrogen sulfide, vinyl chloride and benzene were determined in and around the landfill site. The concentrations of hydrogen sulfide and benzene were calculated to be far below the limit value proposed by the World Health Organization (WHO) for human health safety. However, the vinyl chloride concentrations were above the WHO reference lifetime exposure health criteria for the phase B area.
