%X In order to find out the characteristics of dioxin contamination, we sampled and analyzed the soil and groundwater on a chlor-alkali factory site that uses graphite anode for production. The results show that the toxic equivalent quantity (TEQ) of dioxins in soil samples exceeds the U.S. EPA region screening value (RSL), with the chlorine hydrogen processing workshop, the electric tank workshop, the asbestos stack area, the sewage treatment plant and the oil depot were affected. The dioxin concentration limit of the groundwater sample doesn't exceed the drinking water standard of China. Considering the fingerprints characteristics of dioxin-contaminated concentration, dioxin isomers content and TEQ, the priority pollutants for control on this site are 2,3,7,8-TCDF, 2,3,4,7,8-PeCDF, 1,2,3,4,7,8-HxCDF, OCDD and 2,3,7,8-TCDD. The results show that dioxin pollution is very serious in the chlor-alkali plant that uses graphite anode for production, and the environmental supervision is imperative.
