英文摘要

An analytical method was developed to analyze 5 phthalate esters (dimethylphthalate, diethylphthalate, di-n-butylphthalate, butylbenzylphthalate, di(2-ethylhexyl)phthalate), nonylphenol, bisphenol A and BADGE (Bisphenol A diglycyleter) in distribution and bottled water They are all industrial chemicals used in the manufacture of epoxy resins or paints, polycarbonate and polyethylene plastics (global production of phthalates over 4 Mton/year) or surfactants and have been classified as persistent, with high migration potential from plastic containers and with endocrine disrupting properties. The present paper reports a specific extraction protocol using solid phase extraction with Oasis 60 mg or C-18 cartridges, followed by gas chromatography coupled to mass spectrometric detection using an appropriate surrogate and internal standard for process control. Quality parameters are reported, making special emphasis to limits of detection, reproducibility and blank analysis, which permitted to detect ng L-1 concentrations. In an application step, the method was used to determine target compounds in 7 distribution water and 9 mineral water bottled in polyethylene, polyethyleneterphthalate and glass containers which were analysed upon purchase and after 10 week storage at temperatures up to 30 degreesC. Distribution water coming from different aquifers which at some point are in contact with plastic or painted concrete reservoirs and pipes, contained dimethylphthalate, diethylphtalate, nonylphenol, buthylbenzylphthtalate and DEHP at concentrations ranging from 0.005 to 0.331 mug L-1, depending on the sampled area whereas bottled water showed levels up to 1.7 mug L-1 of some of the studied compounds, attributed to 10 week storage conditions.
