Toxic and heavy metals contamination assessment in soil and water to evaluate human health risk

Abstract Due to urbanization and industrialization, there has been an increase in solid waste generation and has become a global concern and leakage of leachate from landfills contaminate the soil and groundwater and hence can have a severe impact on human health. The present study aimed to determin...
