Study on pollution condition of Phthalate esters in surface water in Nantong city
Objective: To investigate pollution levels and characteristics of Phthalate esters(PAEs) in surface water in Nantong city. Methods:By using solid phase extraction and gas chromatography/mass spectroscope(GC-MS) ,main Phthalate esters in surface water samples from the urban rivers and ponds in suburb were determined. Results:Phthalate esters were detected in all surface water samples, mainly being Di-2-exthlhexl phthatalte(DEHP)、dibutylphalate(DBP) and diisobutyl phatel(DIBP), ranged from 1.27 to 20.40μg/L.PAEs levels in the urban rivers were higher than those in the suburban. Conclusion:Phthalate esters do exist in surface water in Nantong city.
