Abstract
BackgroundThe aim of this study was to provide a scientific method based on Geographical Information System (GIS) regarding all sustainable development measures to locate a proper landfill for disposal of hazardous wastes, especially industrial (radioactive) wastes.MethodsSeven effective factors for determining hazardous waste landfill were applied in Qom Province, central Iran. These criteria included water, slope, population centers, roads, fault, protected areas and geology. The Analysis Hierarchical Process (AHP) model based on pair comparison was used. First, the weight of each factor was determined by experts; afterwards each layer of maps entered to ARC GIS and with special weight multiplied together, finally the best suitable site was introduced.ResultsThe most suitable sites for burial were in northwest and west of Qom Province and eventually five zones were introduced as the sample sites.ConclusionGIs and AHP model is introduced as the technical, useful and accelerator tool for disposal site selection. Furthermore it is determined that geological factor is the most effective layer for site selection. It is suggested that geological conditions should be considered primarily then other factors are taken into consideration.
Highlights
Protecting human health and the environment in a world rapidly becoming more and more complicated and considered as a major challenge for the international community
Various approaches have been investigated in different countries, such as application of iron nanaoparticles in landfill leachate treatment [6], or Converting them into a value added product [7] for usual waste; and for dangerous waste: burying radioactive wastes in shallow pits, waste disposal deep underground, burial in halite formations, burial and disposal at sea and in space
The measures for mapping were obtained from data of various agencies, such as topographic maps scaled 1/50000 of National Cartographic Center (NCC), geological maps scaled 1/250000, the map of political divisions and rural and urban areas of the country, the map of protected areas of Iran Department of Environment (IDOE), provincial road maps provided by Ministry of Road and Urban Development, and ETM images of LandSat
Summary
Protecting human health and the environment in a world rapidly becoming more and more complicated and considered as a major challenge for the international community. Various approaches have been investigated in different countries, such as application of iron nanaoparticles in landfill leachate treatment [6], or Converting them into a value added product [7] for usual waste; and for dangerous waste: burying radioactive wastes in shallow pits, waste disposal deep underground, burial in halite formations, burial and disposal at sea and in space. Remaining these wastes has been a challenge and global growing issue, finding a suitable site for burial them is being deterioration because there are numerous factors and parameters involved. The aim of this study was to provide a scientific method based on Geographical Information System (GIS) regarding all sustainable development measures to locate a proper landfill for disposal of hazardous wastes, especially industrial (radioactive) wastes
