| Abstract: | Samples of groundwater were collected from 17 sites in the Jianghan plain in July 2007. Sixteen phthalate esters (PAEs) were
detected in samples collected by using solid-phase extraction (SPE)-gas chromatography (GC). The results show that there were
one or several PAEs in all the samples, and the concentrations of total PAEs ranged from 80.12 to 1882.18 ng/L. Four PAEs,
i.e. di-isobutyl phthalate (DIBP), di-n-butyl phthalate (DBP), bis (2-ethoxyethyl) phthalate (BEEP) and di (2-ethylhexyl)
phthalate DEHP) were the dominant species. Among these, DIBP, DBP and DEHP concentrations were closely related to the water
supply from the Yangtze River, Hanjiang River and Honghu Lake. However, the distribution of BEEP was irregular, which may
be due to the application of some kind of products containing BEEP in the related areas. PAE distribution was irrelevant to
the electrical conductivity and sample depth. |
