摘　　要：China is one of the most important producers and suppliers of the chlorobenzenes （CBs）, accounting for more than 50% of the world production. Although CBs contamination at the sites of chemical production factories is well-known, the knowledge on spatial distribution and contaminated degree of CBs are still limited. To better understand the occurrence of CBs, a total of 161 soil/sediment samples were collected from 36 sampling points within a 20 m deep from a site of decommissioned chlorobenzenes-producing factory in Wuhan City, Hubei Province, central China. The results showed that monochlorobenzene （MCB） is the predominant contaminants with the ∑CBs levels ranging from 0.05 to 8 600 mg/kg dry weight （dw） with a mean value of 384 mg/kg dw. The vertical distribution of CBs indicated that CBs may have clearly transported to deeper sections in the subsurface. Statistical analyses showed that there are no good correlations between the ∑CBs concentration with soil organic matter （SOM） content and the moisture content.China is one of the most important producers and suppliers of the chlorobenzenes （CBs）, accounting for more than 50% of the world production.
