In that process, DTSC issues a Priority Product Work Plan (Work Plan) identifying the product categories to evaluate over a three-year period. DTSC then considers the product categories through the lens of the Work Plan’s stated policy goals (Figure 1).

In considering the product categories in the Work Plan and our policy goals, DTSC identified BPA, as well as some of its analogues and alternatives, as Candidate Chemicals that may warrant further research regarding their use in food packaging products. This research would address two of the policy goals outlined in the Work Plan:to protect children from exposure to harmful chemicals, especially carcinogens, mutagens, reproductive toxicants, neurotoxicants, developmental toxicants, and endocrine disruptors; andto protect Californians from chemicals that migrate into food from food packaging.BPA is one of the most studied environmental contaminants in the world and has been classified as an endocrine disrupting chemical due to its ability to disrupt estrogen, androgen, and thyroid-hormone mediated biological pathways. One of the major uses of BPA is to manufacture epoxy-based resins that coat the interior of aluminum and steel food and beverage cans. BPA may also be used in other food packaging liners, such as jar lids and bottle caps (collectively referred to as “lids” within this document). Liners protect the metal packaging from corrosion, act as inert barriers to a wide variety of food types, and are sufficiently flexible and adhesive for use during can/lid manufacturing processes. It has been well documented that, under certain conditions, BPA is capable of migrating out of these liners and into food items, leading to the potential for subsequent dietary exposure in humans.Public awareness concerning the risks associated with BPA exposure has created market pressure to remove it from food packaging applications. Many food packaging manufacturers have proactively removed BPA from their products, even though the U.S. Food and Drug Administration considers its use in food packaging materials as safe. However, other bisphenols, such as bisphenol F (BPF), bisphenol S (BPS), and bisphenol AF (BPAF), which are all on DTSC’s Candidate Chemical List, may be used as drop-in replacements for BPA, and many of these compounds exhibit similar endocrine disrupting properties as BPA. Non-bisphenol chemicals may also be used to manufacture can and lid liners, such as glycidyl methacrylate, a possible BPA replacement. Glycidyl methacrylate has been classified as a Category 1B carcinogen and reproductive toxicant by the European Chemicals Agency (ECHA), and is also on DTSC’s Candidate Chemical List. At this time, the prevalence and application of BPA and its chemical alternatives that manufacturers may be using in liners for food and beverage cans and lids are unknown to DTSC. DTSC is requesting additional information from stakeholders about the specific use of bisphenols in food packaging products, the adverse impacts associated with the life cycle of these products, and the availability and feasibility of alternatives. Please see the Questions to Stakeholders section below.Preliminary Screening ResultsHazard TraitsThe hazard traits of BPA are well defined in the scientific literature and include developmental toxicity, reproductive toxicity, endocrine toxicity, immunotoxicity, and neurodevelopmental toxicity.

This compound is also found in an enormous number of other products that we come into contact with daily, and therefore it is not surprising that it has been detected in the majority of individuals examined. BPA is a known endocrine disruptor. Although initially considered to be a weak environmental estrogen, more recent studies have demonstrated that BPA may be similar in potency to estradiol in stimulating some cellular responses. Moreover, emerging evidence suggests that BPA may influence multiple endocrine-related pathways. Studies in rodents have identified adverse effects of BPA at levels at or below the current acceptable daily intake level for this compound. The various reported adverse effects of BPA are reviewed, and potential mechanisms of BPA action are discussed. Much more investigation is needed to understand the potential adverse health effects of BPA exposure in humans and to understand the multiple pathways through which it may act. Although many questions remain to be answered, it is becoming increasingly apparent that exposure to BPA is ubiquitous and that the effects of this endocrine disruptor are complex and wide-ranging.","DOI":"10.1016/j.jsbmb.2011.05.002","ISSN":"0960-0760","shortTitle":"Bisphenol A","journalAbbreviation":"The Journal of Steroid Biochemistry and Molecular Biology","author":[{"family":"Rubin","given":"Beverly S."}],"issued":{"date-parts":[["2011",10,1]]}}},{"id":2312,"uris":[""],"uri":[""],"itemData":{"id":2312,"type":"article-journal","title":"Prenatal exposure to bisphenol A and hyperactivity in children: a systematic review and meta-analysis","container-title":"Environment International","page":"343-356","volume":"114","source":"PubMed","abstract":"BACKGROUND: Attention-deficit hyperactivity disorder (ADHD) has increased in prevalence in the past decade. Studies attempting to identify a specific genetic component have not been able to account for much of the heritability of ADHD, indicating there may be gene-environment interactions underlying the disorder, including early exposure to environmental chemicals. Based on several relevant studies, we chose to examine bisphenol A (BPA) as a possible contributor to ADHD in humans. BPA is a widespread environmental chemical that has been shown to disrupt neurodevelopment in rodents and humans.\nOBJECTIVES: Using the Office of Health Assessment and Translation (OHAT) framework, a systematic review and meta-analysis was designed to determine the relationship between early life exposure to BPA and hyperactivity, a key diagnostic criterion of ADHD.\nDATA SOURCES: Searches of PubMed, Web of Science, and Toxline were completed for all literature to January 1, 2017.\nSTUDY ELIGIBILITY CRITERIA: For inclusion, the studies had to publish original data, be in the English language, include a measure of BPA exposure, and assess if BPA exposure affected hyperactive behaviors in mice, rats or humans. Exposure to BPA had to occur at <3?months of age for humans, up to postnatal day 35 for rats and up to postnatal day 40 for mice. Exposure could occur either gestationally (via maternal exposure) or directly to the offspring.\nSTUDY APPRAISAL AND SYNTHESIS METHODS: Studies were evaluated using the OHAT risk of bias tool. The effects in humans were assessed qualitatively. For rodents exposed to 20?μg/kg/day BPA, we evaluated the study findings in a random effects meta-analytical model.\nRESULTS: A review of the literature identified 29 rodent and 3 human studies. A random effects meta-analysis showed significantly increased hyperactivity in male rodents. In humans, early BPA exposure was associated with hyperactivity in boys and girls.\nLIMITATIONS, CONCLUSIONS, AND IMPLICATIONS OF KEY FINDINGS: We concluded that early life BPA exposure is a presumed human hazard for the development of hyperactivity. Possible limitations of this systematic review include deficiencies in author reporting, exclusion of some literature based on language, and insufficient similarity between human studies. SRs that result in hazard-based conclusions are the first step in assessing and mitigating risks. Given the widespread exposure of BPA and increasing diagnoses of ADHD, we recommend immediate actions to complete such risk analyses and take next steps for the protection of human health. In the meantime, precautionary measures should be taken to reduce exposure in pregnant women, infants and children. The present analysis also discusses potential mechanisms by which BPA affects hyperactivity, and the most effective avenues for future research.\nSYSTEMATIC REVIEW REGISTRATION NUMBER: Not available.","DOI":"10.1016/j.envint.2017.12.028","ISSN":"1873-6750","note":"PMID: 29525285","shortTitle":"Prenatal exposure to bisphenol A and hyperactivity in children","journalAbbreviation":"Environ Int","language":"eng","author":[{"family":"Rochester","given":"Johanna R."},{"family":"Bolden","given":"Ashley L."},{"family":"Kwiatkowski","given":"Carol F."}],"issued":{"date-parts":[["2018"]]}}}],"schema":""} 2,3.

The results showed that two receptors, estrogen receptor alpha (ERα) and androgen receptor (AR), are affected by BPA in opposite direction. To confirm the observed effects of BPA on ERα and AR, we performed transient transfection experiments with full-length receptors and their corresponding response elements linked to luciferase reporters. We also included in this study two BPA analogs, bisphenol AF (BPAF) and bisphenol S (BPS). As seen in African green monkey kidney CV1 cells, the present study confirmed that BPA and BPAF act as ERα agonists (half maximal effective concentration EC50 of 10-100 nM) and as AR antagonists (half maximal inhibitory concentration IC50 of 1-2 μM). Both BPA and BPAF antagonized AR function via competitive inhibition of the action of synthetic androgen R1881. BPS with lower estrogenic activity (EC50 of 2.2 μM), did not compete with R1881 for AR binding, when tested at 30 μM. Finally, the effects of BPA were also evaluated in a nuclear translocation assays using EGPF-tagged receptors. Similar to 17β-estradiol (E2) which was used as control, BPA was able to enhance ERα nuclear foci formation but at a 100-fold higher concentration. Although BPA was able to bind AR, the nuclear translocation was reduced. Furthermore, BPA was unable to induce functional foci in the nuclei and is consistent with the transient transfection study that BPA is unable to activate AR.","DOI":"10.1016/j.cbi.2013.03.013","ISSN":"1872-7786","note":"PMID: 23562765\nPMCID: PMC3722857","journalAbbreviation":"Chem.

BPA has traditionally been regarded as a primarily estrogenic EDC, and this perspective is often what guides research into the effects of BPA.

Such environmental compounds are known as 'obesogens'. Among them, bisphenol-A (BPA) is the most widespread and ubiquitous compound affecting humans and animals. Laboratory animal work has provided conclusive evidence that early-life exposure to BPA is particularly effective in predisposing individuals to weight gain. Embryonic exposure to BPA is reported to generate metabolic disturbances later in life, such as obesity and diabetes. When BPA administration is combined with a high-fat diet, there is an exacerbation in the development of metabolic disorders. Remarkably, upon BPA exposure of gestating females, metabolic disturbances have been found both in the offspring and later in life in the mothers themselves. When considering the metabolic effects generated by an early developmental exposure to BPA, one of the questions that arises is the role of precursor cells in the etiology of metabolic disorders. Current evidence shows that BPA and other endocrine disruptors have the ability to alter fat tissue development and growth by affecting the capacity to generate functional adipocytes, as well as their rate of differentiation to specific cell types. Epigenetic mechanisms seem to be involved in the BPA-induced effects related to obesity, as they have been described in both in vitro and in vivo models. Moreover, recent reports also show that developmental exposure to BPA generates abnormalities that can be transmitted to future generations, in a process called as transgenerational epigenetic inheritance.","DOI":"10.1093/eep/dvw022","ISSN":"2058-5888","note":"PMID: 29492299\nPMCID: PMC5804535","shortTitle":"Bisphenol-A and metabolic diseases","journalAbbreviation":"Environ Epigenet","language":"eng","author":[{"family":"Alonso-Magdalena","given":"Paloma"},{"family":"Rivera","given":"Francisco J."},{"family":"Guerrero-Bosagna","given":"Carlos"}],"issued":{"date-parts":[["2016",8]]}}},{"id":2762,"uris":[""],"uri":[""],"itemData":{"id":2762,"type":"article-journal","title":"Bisphenol A at Environmentally Relevant Doses Inhibits Adiponectin Release from Human Adipose Tissue Explants and Adipocytes","container-title":"Environmental Health Perspectives","page":"1642-1647","volume":"116","issue":"12","source":"Crossref","abstract":"BACKGROUND: The incidence of obesity has risen dramatically over the last few decades. This epidemic may be affected by exposure to xenobiotic chemicals. Bisphenol A (BPA), an endocrine disruptor, is detectable at nanomolar levels in human serum worldwide. Adiponectin is an adipocyte-speci?c hormone that increases insulin sensitivity and reduces tissue in?ammation. Thus, any factor that suppresses adiponectin release could lead to insulin resistance and increased susceptibility to obesity-associated diseases.\nOBJECTIVES: In this study we aimed to compare a) the effects of low doses of BPA and estradiol (E2) on adiponectin secretion from human breast, subcutaneous, and visceral adipose explants and mature adipocytes, and b) expression of putative estrogen and estrogen-related receptors (ERRs) in these tissues.\nMETHODS: We determined adiponectin levels in conditioned media from adipose explants or adipocytes by enzyme-linked immunosorbant assay. We determined expression of estrogen receptors (ERs) α and β, G-protein–coupled receptor 30 (GPR30), and ERRs α, β, and γ by quantitative realtime polymerase chain reaction.\nRESULTS: BPA at 0.1 and 1 nM doses suppressed adiponectin release from all adipose depots examined. Despite substantial variability among patients, BPA was as effective, and often more effective, than equimolar concentrations of E2. Adipose tissue expresses similar mRNA levels of ERα, ERβ, and ERRγ, and 20- to 30-fold lower levels of GPR30, ERRα, and ERRβ.\nCONCLUSIONS: BPA at environmentally relevant doses inhibits the release of a key adipokine that protects humans from metabolic syndrome. The mechanism by which BPA suppresses adiponectin and the receptors involved remains to be determined.","DOI":"10.1289/ehp.11537","ISSN":"0091-6765, 1552-9924","language":"en","author":[{"family":"Hugo","given":"Eric R."},{"family":"Brandebourg","given":"Terry D."},{"family":"Woo","given":"Jessica G."},{"family":"Loftus","given":"Jean"},{"family":"Alexander","given":"J.

There is well-documented and broad human exposure to BPA. The potential risk that BPA poses to the human health has attracted much attention from regulatory agencies and the general public, and has been extensively studied. An emerging and rapidly growing area in the study of BPA's toxicity is its impact on the cardiovascular (CV) system. Recent epidemiological studies have shown that higher urinary BPA concentration in humans is associated with various types of CV diseases, including angina, hypertension, heart attack and coronary and peripheral arterial disease. Experimental studies have demonstrated that acute BPA exposure promotes the development of arrhythmias in female rodent hearts. Chronic exposure to BPA has been shown to result in cardiac remodeling, atherosclerosis, and altered blood pressure in rodents. The underlying mechanisms may involve alteration of cardiac Ca2+ handling, ion channel inhibition/activation, oxidative stress, and genome/transcriptome modifications. In this review, we discuss these recent findings that point to the potential CV toxicity of BPA, and highlight the knowledge gaps in this growing research area.","DOI":"10.3390/ijerph110808399","ISSN":"1660-4601","note":"PMID: 25153468\nPMCID: PMC4143868","journalAbbreviation":"Int J Environ Res Public Health","language":"eng","author":[{"family":"Gao","given":"Xiaoqian"},{"family":"Wang","given":"Hong-Sheng"}],"issued":{"date-parts":[["2014",8,15]]}}}],"schema":""} 14, and immunological diseases ADDIN ZOTERO_ITEM CSL_CITATION {"citationID":"EZwYFGf1","properties":{"formattedCitation":"\\super 15\\nosupersub{}","plainCitation":"15","noteIndex":0},"citationItems":[{"id":2704,"uris":[""],"uri":[""],"itemData":{"id":2704,"type":"webpage","title":"Assessment of recent developmental immunotoxicity studies with bisphenol A in the context of the 2015 EFSA t-TDI. - PubMed - NCBI","abstract":"Reprod Toxicol. 2016 Oct;65:448-456. doi: 10.1016/j.reprotox.2016.06.020.

It is well documented that these groups may have an increased susceptibility to certain toxicants during development, and so exposure to these types of chemicals should be limited.Structural analogues of BPA, such as BPF and BPS, have also been shown to be endocrine disrupting chemicals and to be as hormonally active as BPA, indicating that these are not suitable chemical replacements for BPA in food packaging applications ADDIN ZOTERO_ITEM CSL_CITATION {"citationID":"8gIQ9lCQ","properties":{"formattedCitation":"\\super 19,20\\nosupersub{}","plainCitation":"19,20","noteIndex":0},"citationItems":[{"id":166,"uris":[""],"uri":[""],"itemData":{"id":166,"type":"article-journal","title":"Bisphenol S and F: A Systematic Review and Comparison of the Hormonal Activity of Bisphenol A Substitutes","container-title":"Environmental Health Perspectives","page":"643-650","volume":"123","issue":"7","source":"PubMed Central","abstract":"Background\nIncreasing concern over bisphenol A (BPA) as an endocrine-disrupting chemical and its possible effects on human health have prompted the removal of BPA from consumer products, often labeled “BPA-free.” Some of the chemical replacements, however, are also bisphenols and may have similar physiological effects in organisms.

These have been detected in foodstuffs, house dust, environmental samples, human urine or blood, and consumer products. Compared to BPA, relatively little is known about potential toxicity of these compounds. This scoping review aimed to summarize the human, animal, and mechanistic toxicity data for 24 BPA analogues of emerging interest to research and regulatory communities. PubMed was searched from March 1, 2015 to January 5, 2019 and combined with the results obtained from literature searches conducted through March 23, 2015, in The National Toxicology Program’s Research Report 4 (NTP RR-04), “Biological Activity of Bisphenol A (BPA) Structural Analogues and Functional Alternatives”. Study details are presented in interactive displays using Tableau Public. In total, 5748 records were screened for inclusion. One hundred sixty seven studies were included from NTP RR-04 and 175 studies were included from the updated literature search through January 2019. In total, there are 22, 117, and 221 human epidemiological, experimental animal, or in vitro studies included. The most frequently studied BPA analogues are bisphenol S (BPS), bisphenol F (4,4-BPF), and bisphenol AF (BPAF). Notable changes in the literature since 2015 include the growing body of human epidemiological studies and in vivo studies conducted in zebrafish. Numerous new endpoints were also evaluated across all three evidence streams including diabetes, obesity, and oxidative stress. However, few studies have addressed endpoints such as neurodevelopmental outcomes or impacts on the developing mammary or prostate glands, which are known to be susceptible to disruption by BPA. Further, there remains a critical need for better exposure information in order to prioritize experimental studies. Moving forward, researchers should also ensure that full dose responses are performed for all main effects in order to support hazard and risk characterization efforts. The evidence gathered here suggests that hazard and risk characterizations should expand beyond BPA in order to consider BPA structural and functional analogues.","DOI":"10.1016/j.tox.2019.06.006","ISSN":"0300-483X","journalAbbreviation":"Toxicology","author":[{"family":"Pelch","given":"Katherine"},{"family":"Wignall","given":"Jessica A."},{"family":"Goldstone","given":"Alexandra E."},{"family":"Ross","given":"Pam K."},{"family":"Blain","given":"Robyn B."},{"family":"Shapiro","given":"Andrew J."},{"family":"Holmgren","given":"Stephanie D."},{"family":"Hsieh","given":"Jui-Hua"},{"family":"Svoboda","given":"Daniel"},{"family":"Auerbach","given":"Scott S."},{"family":"Parham","given":"Fredrick M."},{"family":"Masten","given":"Scott A."},{"family":"Walker","given":"Vickie"},{"family":"Rooney","given":"Andrew"},{"family":"Thayer","given":"Kristina A."}],"issued":{"date-parts":[["2019",8,1]]}}}],"schema":""} 19,20.Exposure and Presence in ProductsDiet is the main route of BPA exposure in humans. BPA may migrate out of can and lid liners into food and beverages, leading to dietary exposures. Many variables contribute to the migration rates of BPA, such as food and beverage pH, storage time, temperature, and fat content. Because epoxy-based liners represent such a large portion of the food packaging landscape, exposure to these chemicals is a potential problem for a significant proportion of the general population. Food and beverage cans are widely available in California.
