[Status of trace organic pollution in the network water came from Huangpu River].
OBJECTIVE
To investigate the status of trace organic pollution of the network water came from Huangpu River in Shanghai.


METHODS
An analytical method combining solid-phase extraction technique with gas chromatography coupled to mass spectrometry (SPE-GC/MS) was adopted for determination of trace organic chemicals in water samples. The resins containing XAD-2/402 (1:3) as solid sorbent enriched organic materials from drinking water, and 30% acetone-methanol was employed as elution solvent. 18 GC/MS methods were selected according to the priority substances of hazardous substances in drinking water recommended by US EPA.


RESULTS
142 kinds (10 categories) of organic pollutants were detected from drinking water, including phthalate esters, phenolic compounds, amines, alcohols/acids/esters, aliphatic hydrocarbons, alkyl halides, mono-/poly-cyclo aromatic compounds, heterocyclic compounds, aldehydes/ketones and others. Dibutyl phthalate(DBP), 4-cumylphenol and N-phenyl-beta-naphthylamine were found with relative high levels in the water samples. DBP and dioctyl phthalate (DOP) were considered by EPA to control the priority list of hazardous substances. Herbicides such as atrazine and linuron, and estrogen (3-deoxyestradiol) came from drinking water were also detected.


CONCLUSIONS
Pollutants of drinking water came from Huangpu River as water source were complex. Most of the pollutants detected were not listed into Standards for Drinking Water Quality in China (GB5749-2006), so obviously, their comprehensive harmful effect should be further taken into account.
