“…The levels found in New Zealand foods are low and comparable with international results for fruits, vegetables, soups, corned beef, spaghetti, baked beans, condensed milk and soft drinks (Yoshida et al 2001, Goodson et al 2002. Canned ham, with high levels in the UK study, was not found on New Zealand supermarket shelves and levels of BPA in New Zealand meat products that might be comparable, such as tongue and luncheon, were below the LOQ in the current survey.…”

Exposure to bisphenol A (BPA) from the consumption of canned and bottled food has been determined for New Zealand adults. Eighty different canned foods purchased from retail outlets in Christchurch, New Zealand, between November 2003 and February 2004 were analysed for BPA concentration by gas chromatography/mass spectrometry. BPA was detected in all foods analysed except for soft drinks. Concentrations ranged from <10 to 29 mg kg À1, except for individual samples of tuna, corned beef and coconut cream, which were 109, 98 and 191 mg kg À1 , respectively. The limit of quantitation was <10 mg kg À1 for foods of low fat content (<1%) and <20 mg kg À1 for foods containing >1% fat. Mean concentration data were combined with 24-h dietary recall information for 4399 individual consumers. Mean and maximum exposures were 0.008 and 0.29 mg kg À1 bw day À1, respectively, well below the temporary tolerable daily intake of 10 mg kg À1 bw day À1 given by the European Commission in 2002. The results of the present survey suggest that the levels of BPA identified in canned foods are unlikely to be of concern to adult health, and there is no reason for consumers to change their consumption patterns as a result of these findings. When the concentration data found in the current survey are applied to an oestrogenicity model for an adult male, the contribution of BPA to the total oestrogenicity from 16 food components is 7%. The impact of this level of oestrogenicity remains unclear.

“…15 Bisphenol A (BPA) with a weak estrogenic activity is widely distributed in environmental fields and biological matrices. Many HPLC methods with UV, 16 fluorescence 17,18 and electrochemical [19][20][21] detection, and with mass spectrometry, [21][22][23] have been reported for the assay of BPA in environmental and biological samples. However, most of these methods need tedious procedures such as fluorescence derivatization of BPA and off-line SPE of BPA.…”

Preparation of Uniformly Sized Molecularly Imprinted Polymers for Phenolic Compounds and Their Application to the Assay of Bisphenol A in River Water

2003

Uniformly sized molecularly imprinted polymers, which can recognize bisphenol A (BPA), have been prepared by a multi-step swelling and polymerization method using BPA or a structurally related analogue of BPA [p-t-octylphenol (OP) or p-t-butylphenol (BP)] as the template molecule, 4-vinylpyridine as the functional monomer, and ethylene glycol dimethacrylate as the cross-linker. The BP-imprinted polymer showed higher molecular recognition ability for BPA than the OP-imprinted polymer. The BPA-and BP-imprinted polymers were applied for the assay of a trace amount of BPA in river water using column-switching HPLC with fluorescence detection: A BPA-imprinted polymer was used for removal of BPA from the pretreatment eluent as the trap column, and a BP-imprinted polymer was used for selective pretreatment and enrichment of BPA in river water as the pretreatment column. The calibration graph, constructed from peak area data plotted versus BPA concentration, was linear with a correlation coefficient of >0.999 in the concentration ranges of 25 -1000 ppt. The limit of quantitation was 25 ppt with a 5-ml injection. The column-switching HPLC system was successfully applied for the assay of BPA in river water.

“…These resins are used in dental fillings, food containers, plastic baby bottles, containers for mineral water storage, and food and beverage can linings. The ability of BPA to migrate from polymer to food, especially at high temperatures, has been described-for example, when canned food is heat processed or plastic dishes are used in the microwave (Brotons et al 1995;Olea et al 1996;Yamamoto and Yasuhara 1999;Yoshida et al 2001). Leaching of BPA appears to increase with repeated use of plastic products.…”
