Characteristic distribution of typical contaminants in the soil of a coking plant site in the southwest of China
Abstract：Eighteen profile samples and five surface samples of the soil at a coking plant site in the southwest of China were collected.Total cyanide,heavy metals,volatile organic compounds,total petroleum hydrocarbons,dioxin and so on were analyzed by GC-MS and other methods,and characteristic distribution of theirs in the soil of different functional areas were discussed.The results indicate that the areas around coke pushing line,coal tar recovery point,asphalt conveyor belt and outdoor yard of solid waste of this coking plant are more severely polluted.The concentration of phenanthrene,anthracene,4-methyl phenol,2,4-dimethyl phenol and toluene in the soil is no more than A-level standard value of soil quality assessment for exhibition sites.However,the number of the points over standard of testing total cyanide,mercury,naphthalene,fluoranthene,pyrene,benzo／ pyrene,carbazole,petroleum hydrocarbons is comparatively more.Dioxin in the three tested samples is all detected,but the high I-TEQ value of it is no more than the soil remediation intervention value of Dutch soil remediation circular 2009.
