“…The concentrations of BPA in dosed bottled water and tap-water are 82.4 ng/L and 28.6 ng/L, respectively (Li et al, 2010). After the first week's test of drinking bottled water with a ceramic cup, the GM concentrations of urinary 4-NP, BPA and TCS were 25.96, 1.11 and 7.16 μg/g creatinine respectively (Table 4).…”

“…Urinary BPA had a statistically significant decrease (p b 0.05) when replacing plastic bottled water (7.16 μg/g creatinine) with boiled tap-water (3.49 μg/g creatinine) after the first two weeks, and increased to 4.15 μg/g creatinine after using PC drinking bottle in the third week (Table 4). Since BPA was reported to be released from polycarbonate bottles (Le et al, 2008;Li et al, 2010;Vandenberg et al, 2007), these changed levels of urinary BPA may indicate that drinking plastic bottled water or using PC bottles would probably increase the ingestion of BPA. In the study of Carwile et al (2009), they just assessed the impact of using PC bottles on cold beverages, but did not count for heating factors on PC bottles.…”

“…All samples were collected from people without occupational exposure in Guangzhou. Since BPA were reported to be released from polycarbonate packaging materials (Le et al, 2008;Li et al, 2010;Vandenberg et al, 2007), we designed a three-week test to evaluate the difference of using ceramic cups and polycarbonate bottles that influence the urinary levels of 4-NP, BPA and TCS.…”

“…The use of BPA in food packaging, along with the ability of BPA to leach into the food (7) , has led many to believe that diet is a major route of human BPA exposure (7)(8)(9)(10)(11)(12) . BPA has also been found in products made from recycled paper (21) , dust particles (22)(23)(24) , thermal receipt paper (25,26) , soil, tap water and surface water (27)(28)(29)(30)(31)(32) .…”

Objective: To review the literature on bisphenol A (BPA) exposure and obesity in human populations. Design: Systematic review of the literature via searches of PubMed, EMBASE, Web of Science and reference lists for articles published to 1 August 2014. Setting: China, Italy, Japan, Republic of Korea, Sweden, UK, USA. Subjects: Adults (≥18 years). Results: Eighteen articles were identified and included in the review. Twelve studies included secondary evaluations of BPA exposure and BMI, and six studies evaluated body composition as the primary outcome. All analyses were crosssectional and no study included in the review received a positive quality rating (twelve negative, six neutral). Eight studies observed a statistically significant positive association between urinary or serum BPA levels and BMI, and ten studies observed no association. Studies where BMI was a primary outcome and studies of neutral quality were more likely to observe an association. Conclusions: Study results are conflicting and significant methodological issues limit the ability to draw conclusions from these studies. Prospective studies that measure BPA exposure and changes in body weight and composition are needed to establish temporality, causality and the direction of any observed associations.

“…The observed increases in urinary BPA levels (75) were smaller compared with what was observed with canned food intake (46) . BPA has also been found in products made from recycled paper (76) , dust particles (77)(78)(79) , dental fillings (80) and soil, tap and surface water (81)(82)(83)(84)(85)(86) , but current data indicate these sources of exposure contribute only minimally to overall exposure (59,73,87,88) .…”

Objective: To develop a BPA Exposure Assessment Module (BEAM) for use in large observational studies and to evaluate the ability of the BEAM to estimate bisphenol A (BPA) exposure levels. Design: The BEAM was designed by modifying an FFQ with questions targeting known sources of BPA exposure. Frequency of intake of known dietary sources of BPA was assessed using the BEAM and three 24 h food records as a reference diet measurement tool. Urinary BPA (uBPA) levels were measured as the criterion tool in a pooled urine sample (nine spot samples per participant). Spearman correlations, linear regression and weighted kappa analysis were used to evaluate the ability of the BEAM and food records to estimate BPA exposure levels. Setting: Minneapolis/Saint Paul, MN, USA. Subjects: Sixty-eight healthy adult (20-59 years) volunteers. Results: Dietary BPA intake assessed by the BEAM was not associated with uBPA levels and was unable to predict participants' rank by uBPA levels. BEAM models with all a priori predictors explained 25 % of the variability in uBPA levels. Canned food intake assessed by food records was associated with uBPA levels, but was unable to rank participants by uBPA levels. Multivariable-adjusted food record models with a priori predictors explained 41 % of the variability in uBPA levels. Conclusions: Known dietary sources of BPA exposure explained less than half the variability in uBPA levels, regardless of diet assessment method. Findings suggest that a questionnaire approach may be insufficient for ranking BPA exposure level and additional important sources of BPA exposure likely exist.Bisphenol A (BPA), used in the manufacture of polycarbonate plastics and epoxy resins, is one of the highest-volume chemicals produced worldwide (1,2) and production is predicted to reach more than 4·09 Mt (9 billion lb) by 2020 (3) . Biomonitoring data indicate widespread, chronic low-level exposure to BPA (2,(4)(5)(6) . Animal and in vitro data indicate exposure adversely affects health, but limited and conflicting human epidemiological data is often cited as a barrier for risk assessment by regulatory agencies (7)(8)(9) . While recent epidemiological data suggest that BPA may be associated with alterations in sex and thyroid hormone levels (10)(11)(12)(13)(14)(15)(16)(17)(18) , infertility and polycystic ovary syndrome (19)(20)(21) , obesity (18,(22)(23)(24)(25)(26)(27)(28)(29) , pre-diabetes/type 2 diabetes (23,(30)(31)(32) and CVD (23,31,(33)(34)(35) , most are crosssectional analyses with important limitations, such as lack of long-term exposure data which are more relevant for chronic disease risk (36) . Diet has been considered the primary source of BPA exposure (37)(38)(39)(40)(41)(42)(43) and previous studies support diet as the major route of human BPA exposure (44)(45)(46)(47)(48)(49)(50) . The use of polycarbonate plastics in the production of food and beverage storage containers has been largely phased out in the USA. However, BPA is still used in epoxy resin linings of metal cans and lids (1,2,6,51...
