Risk assessment of gaseous emissions from municipal solid waste landfill: case study Rafah landfill, Palestine

Abstract

This article describes the risk assessment of gaseous emissions from the municipal solid waste at Rafah landfill, Palestine. In this study, Gas-Sim model was used to quantify the gaseous emissions from the landfill and the Land-Gem model was used to verify the results. Risk assessment of both carcinogens and non-carcinogens were performed. Two scenarios were conducted namely with plant uptake and without plant uptake. The scenario with plant uptake revealed that the risk to residents is acceptable for non-carcinogens (risk value 0.45 > 1.0), while the risk to residents is not acceptable for carcinogens (risk value 2.69 × 10–6 < 10–6). The scenario without plant uptake revealed that the risk to residents is acceptable for non-carcinogens (risk value 0.42 > 1.0), while the risk to residents is acceptable for carcinogens (risk value 2.855 × 10–7 > 10–6).
