英文摘要	The aim of the present work is to investigate the distribution and possible sources of phthalate esters (PAEs) in groundwater and surface water of a subtropical Dongguan city, South China. Groundwater and surface water samples were collected from fifty-six and nine sampling sites in 2006, respectively. Concentrations of six PAE compounds (Sigma(6)PAEs) in groundwater and surface water range from below detection limit (BDL) to 6.7 mu g/L and from BDL to 33.8 mu g/L, with an average value of 0.9 mu g/L and 11.1 mu g/L. respectively. Of the six PAE compounds in groundwater and surface water, di (2-ethylhexyl) phthalate (DEHP) and di-n-butyl phthalate (DnBP) are the main compounds of PAEs. DnBP and DEHP are predictive indicators for the Sigma(6)PAEs in surface water (r = 0.803, p < 0.01) and groundwater (r = 0.726, p < 0.01), respectively. Most of high Sigma(6)PAEs in groundwater are measured near the boundary of Dongguan city. In contrast, the Sigma(6)PAEs in groundwater samples are BDL in the center of Doneguan city. The concentration of DnBP in groundwater is negatively correlated with groundwater table (R = 0.6496, p < 0.05), while there is no correlation between DEHP concentration and table in groundwater. Our results indicate the high Sigma(6)PAEs in surface water and the good hydraulic connection between surface water and groundwater. Thus, the PAEs in surface water may be one of the main sources for those in groundwater in the study area.
