Previous studies showed that OCP compounds also occurred frequently in surface water and sediment of Taihu Lake and indicated that OCPs in the surface water and sediment of Taihu Lake may have influenced the concentrations of OCPs in the shallow groundwater in surrounding area of Taihu Lake.
The study area is a floodplain interlaced with a network of canals
and ditches, and the shallow groundwater and surface water interactions
in the study area are difficult to observe and measure (Chen
et al., 2005). To study the impact of the shallow groundwater and surface
water interactions on the quality of the shallow groundwater in
surrounding area of Taihu Lake, we compared the concentrations of
the 14 OCPs in some shallow groundwater samples from the same
