Levels and temporal trend of bisphenol A in composite food samples from Canadian Total Diet Study 2008–2012

Abstract

Food composite samples from the Canadian Total Diet Study which was conducted each year from 2008 to 2012 rotating between different cities were analysed for bisphenol A (BPA). The overall levels of BPA in the composite food samples from each of the five years from 2008 to 2012 were similar in general with averages (range) of 7.7 ng/g (0.20-106 ng/g), 7.8 ng/g (0.26-110 ng/g), 6.9 ng/g (0.20-84 ng/g), 7.7 ng/g (0.20-105 ng/g) and 9.0 ng/g (0.15-90 ng/g) for 2008, 2009, 2010, 2011 and 2012, respectively. Levels of BPA in most of the non-canned food composite samples were low and no particular trends were observed. In contrast, the trend of BPA levels in canned food composite samples over the five years (2008-2012) varies. BPA levels in most of the canned food composite samples from 2008 to 2012 were consistent in general (e.g. canned luncheon meat: 10-18 ng/g, canned baked beans: 18-25 ng/g). While BPA levels over the five years were found to decrease for some canned food composite samples (e.g., canned fish: 109 ng/g in 2009 vs. 51 ng/g in 2012), they were also found to increase for some other canned food composite samples (e.g. canned meat soups: 90-104 ng/g in 2011-2012 vs. 29 ng/g in 2008). Thus, recent changes in can coating for food packaging to BPA-free alternatives may have not been fully reflected in all canned food products over the period from 2008 to 2012. Continued monitoring is necessary to more fully assess the potential impact on dietary exposure by the use of BPA alternatives in food contact materials.

Associations between Dietary Intake and Urinary Bisphenol A and Phthalates Levels in Korean Women of Reproductive Age

“…The particular beverages investigated here were canned and sachet coffee, plastic and can packed tea, soda, and alcohol. BPA is primarily used in the manufacture of polycarbonate plastics and epoxy resins commonly used in plastics and canned food containers [ 37 , 38 , 39 , 40 , 41 , 42 ], which come into direct contact with the foods and beverages and transfer BPA to the contents [ 25 , 26 , 43 , 44 ]. Although, the packaging materials used for the beverages were not investigated here, many studies have revealed that the concentrations of BPA were higher in canned and polycarbonate plastic container beverages than in similar beverages in other containers [ 25 , 26 , 27 ].…”

Easy and Inexpensive Method for Multiclass Analysis of 41 Food Contact Related Contaminants in Fatty Food by Liquid Chromatography–Tandem Mass Spectrometry

“…Bisphenols can be directly analyzed by LC, 11,12 while derivatization is typically applied prior to GC. 13 LC is the method of choice for PFAS, since the use of GC is limited to perfluoroalkyl carboxylic acidsthe only perfluoroalkyl compounds producing stable derivatives for GC. 32 It is obvious that the aim of the present research, to analyze all compounds in a single injection, can only be accomplished by using LC.…”

“…Bisphenol A (BPA) is a synthetic phenol extensively used in the manufacture of polycarbonate plastics and epoxy resins and a component of many everyday products such as liquid and food storages (water plastic bottles, beverage can linings, and food packaging), detergents, and medical and dental devices. Consequently, the human population is continuously exposed to BPA, as revealed by its presence in the environment and populations in general [ 1 , 2 , 3 , 4 ]. BPA can represent a hazard in prenatal life because of its presence in the placenta, amniotic fluid, maternal and fetal blood, and its ability to cross the placenta and reach the fetus [ 5 ].…”
