Description
Summary:To characterize the polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) distributions in the landfill site, co-treated solidified monoliths of fly ash and bottom ash, were investigated. The solidified monoliths, soil, banyan leaves, groundwater in the monitoring wells and the treated landfill leachates in the landfill site for solidified monoliths of fly ash were all sampled to clarify their PCDD/F characteristics. The PCDD/F contents in the surface soils of the landfill site were 460 times higher than that of urban soils and the highest value was 2.8 times higher than the Taiwan soil regulation. The elevated PCDD/F contents in the soil revealed their potential for causing adverse heath risk for humans. The PCDD/F concentrations in the groundwater and the treated landfill leachates of the landfill site for solidified monoliths were both higher than that in the control group.
