Abstarct: The purpose of the present study is to assess the environmental impacts of municipal solid waste disposal in Babolsar beach, Mazandaran Province, on the adjacent soils. For this purpose, 15 surface soil samples and 10 leachates were collected and analyzed using standard methods. The concentrations of major and trace elements in soil and leachate samples were measured by ICP-OES and ICP-MS instruments, respectively. The obtained results indicate that in the soil samples, the concentrations of Ag and Cu in all studied soil samples, and the concentrations of Mn and Ni in most samples, were higher than the world soil average composition. The average values of elements’ enrichment factor followed this trend: Ag (12.6) > Ni (6.3) > Mo (6.2) > Cu (5) > Cd (4.7) > As (4.5) > Cr (3.5) > Pb (3.2) > Co (2.6) > Mn (2) > Fe (1.9) > Zn (1.5). The concentrations of Cd, Co, Cr, Fe, and Ni in leachate samples were higher than the permissible values for leachate disposal into the surface and groundwater resources. The obtained results in the present study show that waste disposal management in the study area according to the environmental guidelines is a necessity, which may prevent the pollution of soil, plants, and water resources in adjacent areas.
