摘要：Seventeen congeners of polychlorinated dibenzo -p -dioxins/polychlorinated dibenzofurans and 16 individual components of organochlorinated pesticides were inspected in the groundwater and soil from the old and new Al-Husainiyah landfills located near the Az-zaatari refugee camp in Al- Mafraq，Jordan. The highest total concentration of organochlorine pesticides and polychlorinated dibenzo-p-dioxins/polychlorinated dibenzofurans were found in the surface soil (0-15 cm) at the old landfill site, withavalue of 88.33 ^g/kg (dry weight) and 2,522.2 ng/kg (dry weight), respectively. The highest sum concentration among the organochlorinated pesticide compounds for all samples was found for P-HCH, with a value of 182.48 ^g/kg (dry weight)，while the highest sum concentration among polychlorinated dibenzo-p-dioxins/polychlorinated dibenzofurans congeners was found for 2,3,7,8-Tet- rachlorodibenzeno-p-dioxin with a value of 2132.11 ng/kg (dry weight). For polychlorinated dibenzo-p- dioxins/polychlorinated dibenzofurans congeners，it has turned out that the highest sum of the Toxicity Equivalent concentration among the congeners was found for 2,3,7,8 tet-Dioxin with a value of 2132.1 ng TEQ/kg (dry weight). Both organochlorinated pesticides and polychlorinated dibenzo-p-diox- ins/polychlorinated dibenzofurans contaminations were found below the method limit of detection in the soil (15-30 cm) and groundwater samples. This environmental study provides up-to-date data for researchers around the world of organochlorinated pesticides and polychlorinated dibenzo-p-diox- ins/polychlorinated dibenzofurans concentrations in Al-Husainiyah as indicator for pollution and comparison purposes.
