Abstract :
In today's growing world that explosive population growth it has an endemic growth of residual and its specific contamination, the environmentalists' minds are concerned about the extent to which the material can endanger the environment, water, soil and air. The unhealthy disposal of solid waste on different organisms at different concentrations and pollution intensities will produce different effects. The purpose of this study, environmental assessment Yazd solid waste landfill for this purpose, environmental sampling of the environmental elements of the current landfill site and determine the composition of municipal solid waste was done. The results of the well water analysis showed a slightly higher concentration of some of the investigated elements in the lower reaches of the burial site than the World Health Organization's (2008) standard for drinking. Soil analysis results showed a slight increase in the concentration of some elements in and near the landfill (in the direction of the slope of the layers), compared to the Canadian standard (2004) for agriculture. The analysis of the well water in the control and sample samples was lower (far from the burial site), and the concentration of the elements was close to the normal range. In relation to the analysis of leachate, the parameters are not consistent with the irrigation and agricultural standards of the Water Pollution Control Agency (2011). Finally, it can be said that the results of the analyzes did not show the widespread and critical effects of burial on the environment, especially the urban environment.
