摘　　要：在西南某焦化场地采集了18个土壤剖面样和5个表层样,利用GC-MS等,对土壤中的总氰化物、重金属、挥发性有机物、总石油烃和二噁英等进行了定量分析,并研究了其在不同功能区土壤中的特征分布。结果表明:①该焦化厂污染较严重的区域主要在推焦线路、焦油回收点、沥青传送带和固废室外堆场附近;②厂区土壤中菲、蒽、4-甲基酚、2,4-二甲基酚和甲苯的浓度均未超过展览会用地土壤质量评价A级标准,而总氰化物、汞、萘、荧蒽、芘、苯并[a]芘、咔唑、石油烃超标点较多;③二噁英在本次所检测的3个样点中全部被检出,但都不超过《荷兰土壤修复通告2009》中的土壤修复干涉值。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.
