摘　　要：为明确焦化厂区环境介质中含氧多环芳烃(OPAHs)的污染特征和致癌风险,采集JD和PF焦化厂植物、土壤和环境空气样品,利用气相色谱-质谱联用仪(GC-MSD)测试其中1-苊酮(1-ANO)、9-芴酮(9-FLU)、蒽醌(9,10-ATQ)和苯并蒽酮(BZO)4种OPAHs浓度.结果表明:PF厂植物、土壤和环境空气中Σ4OPAHs的浓度均高于JD厂,且两厂环境介质中均是9-FLU和9,10-ATQ占主导地位.环境空气-土壤的逸度研究表明PF厂9-FLU处于平衡状态,9,10-ATQ由土壤释放到环境空气中.通过摄入、皮肤接触和吸入3种途径对成人进行了人体健康风险评估,发现JD和PF厂土壤中OPAHs对成人的致癌风险均是可接受的,厂区环境空气中OPAHs的致癌风险对成人也是可接受的.研究结果为OPAHs防控措施的制定提供依据.In order to identify the pollution characteristics and carcinogenic risk of oxygenated polycyclic aromatic hydrocarbons(OPAHs) in the environmental media in the coking plants,vegetation,soil and ambient air samples were collected in JD and PF coking plants.Four species of OPAHs,including 1-acenaphthenone(1-ANO),9-fluorenone(9-FLU),9,10-anthraquinone(9,10-ATQ),and benzanthrone(BZO),were detected using gas chromatography-mass spectrometry detector(GC-MSD).The results showed that the concentrations of Σ4OPAHs in vegetations,soils,and ambient air in PF plant were higher than those in JD plant,respectively,and 9-FLU and 9,10-ATQ were dominated in the environmental media in both plants.The fugacity of ambient air-soil showed that 9-FLU was in equilibrium between the air and soil,and 9,10-ATQ released from soil into the air in PF plant.Human health risks were assessed for adults through ingestion,dermal contact and inhalation.The carcinogenic risks of OPAHs in the soils in JD and PF plants were acceptable for adults,and the carcinogenic risks of OPAHs in the ambient air in both plants were also acceptable for adults.The results provide a basis for the formulation of OPAH prevention and control measures.
