Abstract

Solid waste landfill is one of the causes of air pollution. Polluted gases from landfills (CH₄, NH₃, H₂S, dust,...) can diffuse into the atmosphere easily and cause significant pollution to the surrounding air environment. The study presents the results of air pollution transportation around Dinh Vu solid waste treatment area, Hai Phong city based on semi-empirical theoretical method on the basis of improved Gifford-Hanna model. The transportation calculation results of TSP, NH₃, H₂S emitted from the Dinh Vu landfill show that the northwest area of the landfill is not polluted by TSP, but is polluted by NH₃ and H₂S when the southeast wind blows. In the range from the landfill border to the distance of 300 - 400m, the concentration of NH₃ exceeds the Vietnam standard for toxic gases from 1.26 to nearly 1.3 times; the air environment is polluted with H₂S with calculated concentration values exceeding 3.7-9 times compared to Vietnam standard. The research results contribute scientific basis in the planning of waste landfills and develop strategic solutions to control and minimize the emission of pollutants from landfills in Hai Phong.
