摘要：The influence of sunlight irradiation on the chlorination of pyrene in soil was investigated in this work. The reaction products including original pyrene and chloropyrenes in soil after the irradiation were extracted with benzene-ethanol mixture (4 : 1, v/v) using a sonication technique. The extracts were then cleaned up using florisil column chromatography before GC/MS (SIM) determination. 1-Chloropyrene and dichloropyrene were formed when the soil spiked with pyrene was irradiated with sunlight in the ordinary atmospheric air. The formation of chlorinated pyrenes in soil was also found to be strongly dependent on the irradiation time, kind of soil and water contents. In addition, the formation of chlorinated pyrenes in soil was extremely depressed by the washing of the soil with water, indicating the involvement of water soluble substances as a chlorine source.
